well cocome all of you watc us here, in the united states, canada and around the world. i'm kim brunhuber. it is shaping up to be a very uncomfortable labor day, the western u.s. experiencing record-breaking heat that could put a strain on holiday weekend activities. and the start of a new school year is a time of exciting new experiences, but for children in ukraine, it is marred by the ongoing war. and china warns of retaliation if the taiwan arm sale package a isn't revoked.

we'll discuss the implications on u.s. relations with beijing. live from cnn center, this is c"cnn newsroom" with kim brunhuber. >> we begin with two major weather events unfolding right now. the first here in the united states, a dangerous and blistering heatwave continues its stranglehold in the western part of the country. more than 40 million people are under heat alerts as temperatures soar 10 to 20 degrees above normal and electric companies in california are asking companies to turn off unnecessary lights addrend appliances in order to save energy. and in asiain, a powerful typho is bathering the southern islands with strong gusty winds and heavy rains. luckily it skirted past taiwan

without making a direct hit, but waves hit the northeastern coast. and there is a heavy rain advisory for northern parts of the island. joining us now with the latest on both these stories is meteorologist derek van dam. so records being shattered across the western u.s. and typhoon across east asia. >> yeah, let's start with the heatwave across the western u.s. because this is shattering records, over 155 records, potential high records possible from today right through the middle of this week. just incredible amounts of heat. take salt lake city for example, we have 40 million people under the heat alerts including much of southern and central california and even nevada and parts of utah as well. salt lake city had a record high temperature yesterday of 103 degrees. previous record in the month of september setting 102 was the day before that, so just incredible to see that we're experiencing day after day of monthly record high temperatures

and daily record high temperatures in the same location. so that shows you just how expensive and long duration this heatwave actually is. triple digits across the board for many locations, bakersfield, sacramento, palm springs, vegas, salt lake city and of course death valley. the heat dome responsible for this continues to expand in coverage and we'll see the heat move toward the upper midwest and into the northern plains as well. check out these temperatures, we're expecting daytime highs in the upper 90s to lower triple digits for billings. salt lake city, bismarck as well. i want to bring you to the other side of the planet, another top weather headline, we're monitoring this typhoon that is just off the east coast of china. and it is now still churning over the east china sea. but one thing is for sure, it is regathering some strength. there is the indicator with that little tiny pin hole eye that is the center of the circulation,

the most powerful of the winds currently at 120-mile-per-hour or roughly 195 kilometers per hour. this particular area will side swipe eastern sections of china including shanghai. but the bulk of the strongest winds are on the eastern side. so we'll spare the area with the worst of the typhoon, but we're not done just yet because it will pick up in forward trajectory and move into the southern coronkorean peninsula. so we anticipate a near landfall or direct landfall for this particular area. not only is the wind concerning but also the potential for extreme flooding across this area as the official forecast track crosses right over south korea. >> and we'll be monitoring both of these stories throughout the weekend. derek, thank you so much. new launch date could be weeks away or even longer after a second failed attempt to send the unmanned artemis 1 rocket beyond the moon and back.

engineers couldn't fix liquid hydrogen leak in time for a safe saturday liftoff, so technical forces nasa to scrub the launch for the second time. stakes are huge as nasa hopes future missions will return humans to the lunar surface, but the head of nasa says it is better to be safe than sorry. >> we do not launch until we think it is right. and these teams have labored over that, and that is the conclusion that they came to. so i look at this as a part of our space program of which safety is the top of the list. >> officials will decide in the coming day what is do next with arrtemis 1. next available launch period is more than two weeks away.

dangerous moment in the skies over tupelo, mississippi saturday. police have arrested and charged an airport worker that they say stole a plane and threatened to crash it. pete muntean has the details. >> reporter: this is quite possibly the best possible outcome of this incredible story in tupelo, mississippi where an employee of a local airport was able to get out on to the ramp, get into a twin engine beachcraft king era commuter plane that seats about six people, take off and then he said that he was going to crash into a local walmart. police in tupelo finished a briefing in which they laid out the scenario. around 5:00 a.m., they say that cory wayne patterson called 911, laid out that he was going to crash the plane into a local walmart. police were able to put negotiators on the phone with him and then they brought in another pilot who attempted to talk patterson back to the

tupelo regional airport and try and have him make a landing. what is so interesting is that police say patterson came within 100 feet of a successful landing but he went back around again, flew up to the northwest, they thought that he was going to run out of fuel, they lost contact with him via phone. and then they regained contact with him via phone when he said that he was in a farmer's field and the plane had crash landed. police showed up in in gravesto mississippi, they say that they were able to detain him without much incident and the plane is relatively intact. what is so interesting here, patterson was an employee of tupelo aviation where he was fueling planes for a living. so police say that he did have access to airplanes as part of his job. it is a harrowing story that he will now tell in a courtroom. patterson is charged with grand larceny and making terror istic

threats. pete muntean, cnn, washington. and most residents in jackson should have water pressure but it still remains unsafe to drink. city officials say that there have been significant gains at the water treatment plant. it has been nearly a week since the main water facility failed in part because of historic flooding. tens of thousands are struggling to access clean water and the white house says climate change denial has contributed to the problem. >> first of all, they have to beacknowledge that there is a problem. i think what has happened is that lot of the fixes that are being used are fixes that were probably would have worked 20 years ago but they won't work anymore. and we have to make sure that we build systems that can deal with flooding, deal with systems that can deal with rising water tables. and all of these issues are not being addressed currently especially in places that don't even acknowledge that climate change is real. and until they make that allege

knoc acknowledgement and make the adjustments with working with the bipartisan infrastructure plan to build systems that are resilient, then we'll continue to have these problems. but as long as they think that poor people and people of color can live with these mediocre systems, we'll continue to have these problems. >> jackson officials say repair teams from georgia and florida are also on site. death toll from massive flooding in pakistan has risen to almost 1300 people which leads to the question why are the floods so bad this year? pakistan's chief meteorologist says climate change is a part of the problem, and it is not just more intense monsoons, it is also element willing glaciers. jennifer gray has the story. >> reporter: pakistan is coping with its worst flooding tin living memory. more than 1100 people have died, hundreds of thousands are homeless and tens of millions of people are impacted.

pakistan's chief meteorologist is pinning the blame on climate change. >> translator: basically the reasons behind the floods were the factors supporting our rainfall. pacific ocean temperatures, indian ocean temperatures, and there has been excessive heat from march to june. and that excessive heating created low pressure and the monsoon access remained tilted to the south. which is why more rainfall occurred in southern pakistan. >> reporter: the south asian nation of 225 million people saw the heaviest rains on record with little relief since mid june. some areas have seen five times their normal levels of monsoonal rainfall and the most by far ever recorded in one season in the country. but climate change is not just affecting the monsoon. it is also melting glaciers which is adding more water to the floods. >> translator: this year in our

northern areas, 16 glacial lake outburst flood incidents took place. such incidents occur after glaciers melt due to rise in temperature. normally there are five or six such events, but this year there were 16. climate change is the basic reason for such things. >> reporter: the flooding has had a devastating impact on a country that is responsible for just 1% of the world's planet warming gases according to data by the european union. the global climate index found that pakistan is the eighth most vulnerable nation to the climate crisis. >> this is one of the world's hot spots. people living in the hot spots are 15 times more likely to die from climate impacts. as we continue to see more and more extreme weather events around the world,s it is climate protection is being put on the

back burner as greenhouse gases are still rising putting all of us everywhere in growing danger. >> reporter: officials say the estimated cost of the recovery efforts could be $10 billion. and it may take years to rebuild. jennifer gray, cnn. if you want to help the millions of people impacted by the definite investigation starting floods in being pa stand, you can go to cnn.com/impact. ukrainian students head back to school, but it is hardly a break from the war. have a look.

i'm lindsey vonn, and ever since i retired from skiing, i've had trouble falling asleep and staying asleep. you know, insomnia. before i found quviviq, an fda-approved insomnia medication for adults.

you would not believe the things i used to think about when i couldn't sleep. hey, linds. i need you to sign this business contract. all 114 pages. lindsey, lindsey!! hey, lindsey! it's workout time. hey, big man, we're in the middle of something here. yeah, it's called physical fitness. just a couple dozen more questions, lindsey. don't forget to pack your phone charger for tomorrow morning's flight. it's plugged in right over there. insomnia can impact both my days and my nights. that's why i take quviviq nightly. quviviq can help you fall asleep faster and stay asleep longer, and more sleep at night may mean feeling less tired during the day. quviviq works differently than medication you may have taken in the past. quviviq is thought to target one of the biological causes of insomnia. overactive wake signals. do not take quviviq if you have narcolepsy. don't drink alcohol while taking quviviq or drive or operate heavy machinery until you feel fully alert. quviviq may cause temporary inability to move or talk or hallucinations while falling asleep or waking up. quviviq may cause sleepiness during the day. quviviq may lead to doing activities

while not fully awake that you don't remember the next day, like walking, driving and making or eating food. worsening depression including suicidal thoughts may occur. the most common side effects are headaches and sleepiness. it's quviviq. ask your doctor if it's right for you. ukraine's largest nuclear plant has lost its main connection to the power grid again despite the presence of international inspectors. ukrainian officials say

artillery fire hit a working power line out of zaporizhzhia plant saturday. after that ukraine says one of the two operating nuclear reactors was shut down and emergency procedures were activated but the other reactor is still delivering a limited amount of electricity through a backup line. kyiv and moscow have blamed each other for shelling at the plant. the watchdog inspectors say a backup line can also deliver power into the plant which is needed to cool the reactors and prevent them from melting down. the facility temporarily lost connection to the grid last week as well for the first time in its history. ukraine says one person is wounded after a russian rocket strike in the east. this was the scene in the city of kramatorsk on saturday after russian rockets hit a local market. it also destroyed nine vehicles. and ukraine says that it is pushing ahead with its offensive in the south. military officials say they have been striking russian command

centers, supply lines and pontoon crossings across the region. there are indications that ukrainian troops have made modest gains despite russian counterattacks. president zelenskyy says ukraine is also scoring victories in the skies. here he is. >> translator: today our air force has a good result. down caliber missile and attack helicopter of the occupiers, drones, each such result of safe life of our citizens and opportunity not to be afraid for all our people. we will do everything so that ukraine can fully defend its skies from russian aviation. this is one of the fundamental issues for our country. ukrainian artillery is doing everything to destroy the viking potential of the occupiers so that every russian headquarters and all their ammunition depots all logistical routes in the occupied territory are neutralized. >> for more, melissa bell is joining from us kyiv.

first let's get the latest on the shelling from the nuclear plant. >> reporter: because the iaea inspectors are inside, that that might quite things along it, but yet it sits on the dnipro river which is the frontline, on the right side ukrainian forces and the left bank just to the south of zaporizhzhia itself lies that nuclear power plant which has found itself since march in the hands of russian forces. now, what had been imagined is that because those six inspectors are still there, and due to deliver their report early next week, that might calm things around the plant. sadly that has not been the case. so shelling once again shifting off that fifth reactor according to the ukrainian nuclear operator which continues to operate the site even though it is in russian hands. so again, exactly what the head

of the iaea mission had said when he was there thursday, it is that that has to stop given the dangers that are involved. and it is dangerous do with the power supply that people are really worried about because that is what has the potential to really cause those reactorst power supply that people are really worried about because that is what has the potential to really cause those reactors no longer to be cooled. we'll hear from the nuclear inspectors, the iaea inspectors, early next week. the idea is that permanent presence remains but clearly that has not been enough to stop the shelling around the plant. we don't know yet who is responsible. we're hearing this from the ukrainian nuclear authority. they say russian forces that are responsible. they had in the past been using the plant as something of a military base from which to launch attacks according to ukraine. we don't know exactly from where the shelling has taken place. >> so despite this nuclear threat, despite all of the

fighting, ukrainians across the country are trying their best to get back to some semblance of normality. is that right? >> reporter: that's right. it is quite a surreal situation where most of the country you wouldn't know was at war, apart from the odd siren. this has been the case for some time ever since really russian forces pulled back to their eastern positions and went on to take the south. the counter offensive continues in the south, but ukrainian authorities are being tight lipped about its progress saying that they are making progress, not really giving any access to journalists for the time being. but kyiv and to the north of kyiv that had known such violence at the start of the war, there was some return to normality for the country's schoolchildren. preparing for the first day of school is always nerve-racking especially in ukraine where hannah and max headed back to class on thursday for the first time since the war began.

>> reporter: the truth is you never know where the missile will hit, the school or the house. we went to the school several times and examined the bomb shelter. we believe that everything will be fine with our children in terms of safety. >> reporter: it was to a school rebuilt that the children headed. irpin was at the heart of it when the war began but now six months later, peace has been restored but the threat it might be shattered is never far. the drill, more troubling for the parents it seems than for the children themselves. here we have not forgotten that the war is going on. every day we see destroyed houses and it is difficult. the smily children i see today doesn't mean i'll having fun

inside. children should not see what we adults are going through, but our hearts are breaking. we're in a lot of pain. for the children it was return to life as it should be. ♪ there is a list of games to be played in sheltersrise to give of normality or at least as much as the war allows. and that for a lot of people matters a great deal, kim, that life can continue as though nothing were happening. and yet all eyes very much in cities like kyiv on what is happening in the south, that counteroffensive, a great deal of hope pinned on the possible advances of ukrainian forces. what we have been hearing from the head of the local military is that they believe that the offensive is happening in such a way that they are making progress. but most of all, they are p

preventing referendum from taking place that would lead to annexation of a fifth of ukraine that is now in russian hands. >> appreciate the reporting. melissa bell in kyiv, thanks so much. u.s. special envoy to the horn of africa is expected to travel to the region on sunday and then visit ethiopia in the coming days. the trip comes amid renewed clashes between ethiopian forces and tiggerian fighters. lara hlarry madowo has the latet on the conflict. >> reporter: this make shift aid center has become a daily task for these women in this town. this video was captured in june and july where the catholic missionary who runs the small center says that the situation has become even more dire since then. the missionary says hundreds

arrive daily as early as 3:00 a.m., children in tow, desperately seeking any food aid. but every day is the same. only small amounts of a porridge like drink are available here. the war has left more than 90% of the region in urgent need of assistance. in march, a fragile humanitarian truce finally allowed aid to start flowing in, but with little fuel to distribute supplies, what has arrived still has not translated in to increased humanitarian assistance. >> our colleagues are telling us that the humanitarian situation in northern ethiopia continues to be alarming. >> reporter: much of the aid has been in the capital far from the areas where it is needed the most. but fighting flared again last week raising new concerns about aid distribution. >> we of course renew our call

on the parties to the ckconflic to immediately facilitate the unimpeded passage of workers and supplies into all of northern eth ethiopia. >> reporter: one 38-year-old single mother told cnn that her kids are weak and prone to illness without regular meals. still they join the queue early hoping for whatever nourishment that they can get. on days there is not enough, they skip school to beg door to door. head of w.h.o. calls it the worst disaster. >> i can tell you that the humanitarian crisis is tegray is more than ukraine. without any exaggeration. and i said this many months ago many the reason is the color of the skin of the people in

states, canada and around the world. i'm kim brunhuber. we're following a developing story in the state of south carolina, police in charleston say at least six people were wounded following a shooting ove overnight. police responded to reports of gunshots in the downtown area and found multiple people had been hit. the victims are being treated at local hospitals, but the extent of the injuries are unknown. it is not clear if police have identified a suspect and the investigation is ongoing, so we'll bring you the latest as we learn more. a federal judge is expected to decide soon on donald trump's request for a special master to review classified materials seized from his home last month. but even trump's former attorney general says appointing a special master is unnecessary. marshall cohen has our report. >> reporter: new details in the mar-a-lago investigation, we're learning more about what the fbi recovered from former president

trump's south florida resort during the unprecedented fbi search last month. federal agents found 103 classified documents. that is a startling number because before the search, one of trump's attorneys told the doj in a sworn statement that there were not any documents, any classified documents, left on the premises. investigators also seized more than 11,000 nonclassified presidential records eve, and e though they are not classified, prosecutors say that they are government property and should not have been taken to trump's resort in the first place. and we're also learning that according to court filings the classified materials were found intermingled with news clippers, magazines, even gifts and clothes. this confirmed investigators' suspic

suspicions that they were not being secured at mar-a-lago. stw trump is still fighting to have a special master appointed. the judge in the case seems to be leaning in trump's favor. she asked some tough questions of the doj and she's already publicly signaled her preliminary intent to name a special master. but outside of court, the justice department found an unlikely ally in former attorney general bill barr. of course he was a true trump loyalist during his tenure. he has since been more critical of trump and in a fox news interview, barr backed up some of the justice department's main arguments in this case. take a listen to what he had to say. >> i think the whole idea of a special master is a bit of a red herring at this stage since they have already gone through the documents, i think it is a waste of time. >> reporter: but of course it is not up to barr, it is up to a federal judge down in florida. her name is eileen cannon.

she's a trump appointee, she is handling this case and she could hand down her decision at anytime. marshall cohen, cnn, washington. trump condemned the mar-a-lago search saturday, but he didn't stop there. here is what he said about u.s. president joe biden at a rally in pennsylvania. >> he is an enemy of the state. you want to know the truth. the enemy of the state is him and the group that control him which is circling around him, do this, do that, joe, you better do this, joe, right? >> that was the moment when a rmg for every u.s. president accused the current president of being an enemy of the state. trump's counterattack was in response to president biden calling trump and his maga allies an extremist threat. trump was in pennsylvania campaigning for senate mehmet oz and also gubernatorial doug mastriano. but a fcharlie dent spoke with

earlier here. >> it seems that the country is hopelessly polarized. you know, president trump is up in wilkes-barre criticizing the fbi. and i have to be honest with you, you know, any member of congress ob skounded with classified material, i can assure you that somebody from the fbi would have shown up at their honds and demanded had they return that information. so i'm not so sure that former president trump did anyone any good with that speech tonight. just by showing up in pennsylvania, he is making the election much more about himself and of course most republican candidates don't want anything to do with donald trump in this general election. they want this to be about joe biden and the democrat. but to the extent trump inserts himself into this conversation, he is giving the democrats a major gift right now.

>> that was former republican congressman charlie dent speaking with me earlier. voting is over and winner will be announced tomorrow in the race to become the next leader of the uk conservative party who will automatically become the new british prime minister. a broad field of contenders was whittled down to just liz truss and rishi sunak. boris bo boris johnson is expected to submit his resignation tuesday. scott mclean is joining us live from london. so tell us what we'll expect over the next two days. >> reporter: for the vast majority of the people in this country who will not be voting and have not voted for the new prime minister, this race is sort of sperk late management background over the last month or two. the most exciting part actually happened in the first few days when conservative party mps whittled down the field. quite a large field down to just

two. liz truss and rishi sunak, the man whose resignation arguably sparked the begins oning of thed of boris johnson in the first place. the criticism of the system is is that the wishes of mps don't necessarily reflect the wishes of the broader electorate and the conservative party members, don't necessarily reflect the electorate and in the uk more broadly. case in point, 2008 study found that 97% of members were white, 61% over 55. and these are the only people choosing the next prime minister and they make up just 0.4% of the overall uk electorate. what is interesting, the same study also found that the other major political parties had very similar numbers when it comes to being majority male, more than 95% white and also quite

affluent compared to the rest of the population as well. if you believe the polls, liz truss is likely to be named the new prime minister of the uk tomorrow. the talk shows in this country, political talk shows, are already talking about her as if this is sort of a done deal looking forward to what she might actually do. as for boris johnson, he has written a message to the country in a newspaper and he is really calling for party unity and he wrote this in part, this is the moment for every conservative to come together and back the new leader wholeheartedly, this is the time to put aside the disagreements of the last few weeks fascinating though they may have been and put the national interests first. after often exhilarating years, i know how big and demanding this job is and i also know that either candidate is more than capable of delivering for the people of this country and kim i have to tell you the challenges are enormous. not only do you have inflation

but you also have the rising cost of energy which is dominating the headlines here. you have unions going on strike, of course you have war going on in ukraine, you have the state of the health care system, the list goes on and on. what we're expecting from liz truss according to the british press, that she will make an announcement quite early on as to what she will do about the cost of -- rising cost of energy really hitting british households quite hard, an issue very likely that will one of the defines points of her leadership as prime minister. >> if she wins. >> reporter: of course, yes. >> scott mclean, thanks so much. polls open in chile in just a few hours. on the ballot a sweeping new constitution described by some as a christmas tree of guaranteed rights for virtually everyone. voting is mandatory and officials say there is no reason not to participate. >> translator: all the schools are ready. as you can see, there is order and tranquility in the polling

stations as there should be. we guarantee that citizens can exercise their right to vote which is the right thing to do in a democracy. >> existing constitution was imposed during the dictatorship more than 40 years ago. nearly 80% voted to scrap it in october of 2020, but polling suggests support for the proposed alternative has cooled off considerably with many people now concluding that its lofty goals are simply unrealistic. china is warning of consequences over a new u.s. arms deal with taiwan. we'll have detail on the deal and what it means coming up.

chooif ina threatening countermeasures after new arm sales to taiwan. the deal includes the sale of potentially hundreds of missiles

and it is after recent high profile officials met with taiwan. they say that it will seriously jeopardize america's ties with beijing. for more, i'm joined by professor of war and strategy in east asia at kings college london. thank you so much for being here with us. so this is the first arms sale to taiwan under the biden administration. how significant is this for taiwan? >> this is very significant. if anything, it is a powerful reminder of the fact that the military balance across the straight, it is a constantly moving target. and since 2020 when the president was reconfirmed with a landslide victory, the military tension has been consistently and constantly increasing. so the biden administration has played this very carefully to avoid precisely giving the

impression of stoking up the fires of tensions across the strait. but given what we're seeing this past summer, the sale announced now, it is a powerful statement in that sense of the important role that the united states has to play in maintaining that military balance across the strait with denial capabilities that are important in the air and concerns of the taiwanese defenses. >> yeah, i want to ask you about that denial capability. specifically the types of weapons that we're seeing. i understand there has been a bit of a shift in strategy to use smaller weapons that could be used to counter a larger force kind of like we've seen in ukraine for example, a focus on missiles and mobile artillery rockets, the himars systems. >> that is an excellent point. and the answer to your question has two elements to it. first of all, the taiwanese have changed if you want their strategic approach to their defense problem with the

so-called porcupine strategy. and it is exactly what you say, rather than pursuing fewer high end of the spectrum capabilities ideal for the high intensity kinetic context, what they are trying to do is to sort of increase the distribution across a smaller capability which is are harder to detect so a lot more strain over the potential enemy but at the same time increase availability and therefore the denial effects which is really what you want to have there. so you've got that on the one hand. and the united states on the other has been sort of like playing a role in trying to support particularly sort of in light of what is happening in ukraine and what we've seen in ukraine, both this washington and taipei, there is a growing awareness that that change of that strategy that i mentioned, it is the right pathway and it is the one that really sort of

gives a new attention, a new focus in terms of the type of capabilities. and as you say anything that allows to increase that sort of anti-air and denial maritime sort of space and also much stronger surveillance and early detection capabilities. because these are the ones that will make beneficial effects of that sort of distribution over smaller denial capabilities. >> yeah, interesting how one conflict can inform another. let's pivot to china's reaction announcing that they will take countermeasures. what form could that take and are we talking sort of short term or longer term do you think? >> i think it will be both. and it must be said that the exercises that were conducted this summer, can which also were represented by the chinese as part of a response to the nancy pelosi visit, i think, you know, they were very large in scale, they deployed considerable

amount of -- critical amount of capabilities, but at the same time, they didn't cover a whole sort of spectrum of other actions that could have been undertaken. for example, there was no amphibious assault exercise during that period of time. this is to say what? that the chinese have been very strong with the their narrative but also relatively careful in the way that they opportunistically took advantage of the situation. so what we expect to see is more of the same. we now have an idea that they have been pushing across the median line with the incursion in areas that put a lot of strain on taiwanese defenses. more of that is likely to happen and we've seen also an increase in the naval maritime assets. and indeed around the island itself. what we can also see is greatest sort of stress on the offshore islands under taiwanese control which remain the next big step
