home of super bowl lviii between the 49ers and the chiefs, this is kpix cbs news bay area. just as advertised, the atmospheric river has arrived and the worst is yet to come. we are tracking when and where we will see the messiest conditions on this first alert weather day. two bay area sisters are making a difference in the fight against alzheimer's. how they are doing it with a message in a bottle. bay area unite. the warriors are showing love to our super bowl bound 49ers. thank you for joining us this afternoon. we are in the thick of the storm right now. let's get right to meteorologist darren peck, tracking the wind and rain from our virtual view studios. we are starting with the rain. this is moving through and starting to notice the rain. i want to show you why the rain will get more impressive over the next five

or six hours. we leave behind this latest frame on first alert doppler and there is so much rain on here, it is hard to get your bearings. you can see where san francisco is. i will switch this to futurecast and we will notice there is a line of rain that goes along with this. you can see the timestamp up there from 3:00. as we play this forward, we can march this across the bay through the evening commute. the thing that works out about this is just as most people are having to get on the roads through some of the most trafficked parts of the bay , we are going to be seeing some of the best of the rain from this whole system come across. you've got to plan on wet roads, slick surfaces, even some ponding of water on roadways. look at the 6:00 hour, right through the bay. it is still raining in the north bay but we have the most steady rain through here. this gets us to 7:00, 8:00 and that is where it is primarily in the santa clara valley. once we get toward 10:00, we will start to

clear out the widespread steady phase of the system and enter a second phase. there is a chance of rain for thursday or friday. you will see every day has a chance of rain on it on the 7-day forecast but today is unique in terms of the amounts and the totals. thursday and friday sprain will come in the form of isolated, on and off again, hit and miss showers. some of them will have localized brief downpours in them . we will also get plenty of breaks of blue sky on thursday and friday but then the sky will darken and you will see an isolated shower and a brief downpour. the main rainfall totals are coming between now and midnight. because of those, that is why we have the flood watch for the entire bay area but the northbay is always a special concern just because of the watersheds. here is the russian river. you can see the timestamp across the bottom. this gets us to friday morning. the black line shows you where we will crash. that is the most

detailed forecast. there is a lot of possibility in purple. look at the black line. the russian river, while coming close to monitor stage late thursday and friday, should not be exceeding it but we need to watch it. when you look at the rainfall totals, you can see why. this is still the rain to fall in the northbay. most of the rain still has not fallen yet from the city, south. those totals get you down into the santa clara valley. this is an atmospheric river. it is a pineapple express. you can see how why you. we are pulling and a warm tap of subtropical moisture. this is the official forecast on the intensity of this. let's just pull out the details and you can see it falling in the shades of green. this is a category 2 on a scale of one to five. this is a moderate atmospheric river from a rainfall standpoint. the wind is something different and

there is a high wind warning that stays in effect from now through tomorrow morning at 4:00 in the primary areas of concern, santa cruz mountains, the peninsula and now the east bay hills because the wind will be strong enough over those ridge tops that any vulnerability to weaken trees that could go down, that would be the biggest concern for now through 4:00 a.m. tomorrow. keep that in mind. it is really the communities right along skyline and those higher elevations. let's get into the 7-day forecast. there is another system coming our way after this one. you can see that coming through on sunday. a chance of scattered showers and isolated thunderstorms thursday and friday. saturday, the showers pick up more and sunday appears to be the day for the next widespread steady rainmaker with even more impactful wind. that will quickly become the fourth -- focus of the forecast. we will get you ready for sunday

throughout the course of the next two days. for now, back to you. we are seeing some storm damage in the santa clara county. this large tree toppled over a truck in saratoga. fire crews say a girl was trapped and they were able to get her out. she was taken to the hospital and is expected to be okay. the wind and rain are not stopping some folks from going about their day in santa rosa. this is what it looked like on fourth street. some stores had sandbags just to be precocious. state officials are doing their part in preparing for the storm. cal oes is preparing emergency crews for anything the weather brings across the state. >> what we are looking at is not just what will happen today and tomorrow but this is a longer duration event. one of the things we are concerned about is not just the rain but the wind. there is significant opportunities for widespread power outages. >> pg&e is ready to respond to

blackouts and downed power lines. they will be keeping a close eye on the santa cruz mountains. we will be tracking this storm and its impacts throughout the day and night with first alert weather updates anytime. just head to our website, www.kpix.com or watch us streaming on the free cbs news app . let's check in with anne makovec for a look at your news headlines. we are getting the latest on the federal investigation into that plane crash that we reported yesterday. it was a small plane that went down in concord. taking a live look now as the ntsb continues to give an update. basically they have said what we already know, the plane landed at the intersection of concord avenue and diamond boulevard. those streets remain closed today. crews say the plane dove into a car and the pilot died. the driver was hospitalized with minor injuries. if there are any significant developments coming out of this news conference, we will bring you them. tech leaders were in the hot seat in washington d.c. today. the ceo of meta,

discord and x were all on capitol hill and testified about what their companies are doing to protect children from sexual exploitation online. democrat and republican senators, along with victims' families levied heavy and emotional criticism against the ceos, saying they are not doing enough. meta ceo mark zuckerberg stood and apologized to all of the families in the room. police have arrested the suspect whom they believe fired shots into a church in south san francisco. it happened at saint augustine catholic church. nobody was hurt. the suspect, 22-year-old jabari augustine is facing charges including attempted murder. with 11 days until super bowl lviii here on cbs, uniting with the niners. members of the team are invited to last nights warriors game at chase center where they sat courtside and got hugs from steph curry and draymond green before the game.

they received custom dubbs jerseys. we are your station for super bowl lviii. you can watch the game right here on kpix and streaming on paramount+ on february 11. we will have much more coverage leading up to the super bowl around the bay area and in las vegas. on the healthwatch, more than 6 million americans are living with alzheimer's and an estimated one in three seniors will die of alzheimer's or another form of dementia. according to the alzheimer's association, it kills more people than breast cancer and prostate cancer combined. alzheimer's can be devastating to not only the person suffering from the disease but also the loved ones who are watching them fade away. i met up with two sisters who wanted to do something after their grandmother was diagnosed with dementia, proving you are never too young to make a difference. >> reporter: 15-year-old charlotte and 12-year-old alexandra share almost

everything, a competitive edge on the tennis court, a passion for music, taking care of their chickens, and a love for their grandmother, who they called oma . >> we always loved having her here. she is so sweet and so kind. she loves nature and the outdoors. i always remember her amber necklace. i really loved that one. she was very creative. >> the sisters would cherish her annual trip from germany to visit them over the holidays but a few years ago, they noticed something was different. >> we did not know what it was at the time but she would forget our names or makes us up. she would mix place the utensils will repeat the same question. >> when we say that there is no cure, oma will get worse, they did not like that very much and they wanted to know , who is

out there helping? >> they remembered the analogy their parents used when explaining what was happening to their oma. >> they used the analogy of a bottle and they said people's memories and experiences are like messages in a bottle and sometimes you get older over time and the content inside the bottle changes. >> they got to work, making arrangements inside used wine bottles. the girls get their hands dirty working with the plans, their mom tries to keep her is intact. >> i still have 10 fingers, which is good. a lot of cuts but we don't let the kids handle it. i cut and i send and they just use it. >> the arrangements are different each year but oma is always there inspiration. this year, the sisters used succulents to honor their grandmother's resilience. >> last october, she broke her hip and this year, she is using a walker and doing well. she is

physically fit. we wanted to do something that would be like that. >> they hand deliver each arrangement. >> thank you so much! >> hoping their message in a bottle could not only spread joy but also change. >> the sisters come up with a theme for their arrangements in september and then they deliver them through the holidays. they raise over $2000 a year and all the proceeds go to the alzheimer's foundation. potential advances in detecting alzheimer's. how a new blood test may be a step

when it comes to alzheimer's disease, the earlier the detection of this disease, the better. now, a new study said tests a simple blood test that screens for alzheimer's maybe a step closer to reality. researchers say the test is much less invasive, less expensive and potentially more accessible than traditional screening tools and they say it has high accuracy not only in detecting alzheimer's but also catching

the disease even before symptoms begin to show. for now, the test is only available for research use. joining me like now is dr. sharon shaw . thank you so much for joining us, dr. shaw. >> let's talk about alzheimer's diagnosis. what is the rate now you are seeing compared to five years ago? >> it is definitely increasing and we know that alzheimer's has a risk of developing it and increases as we get older. as we live longer, the likelihood of developing alzheimer's disease increases. as you said earlier, 6.7 million americans have alzheimer's disease and that number is rising every time we report on these numbers. >> what do we know about the causes of alzheimer's? it differs from person to person. sometimes it is genetic, sometimes they think it might be caused by something in the environment. what are they

finding now? >> we know about the pathology of alzheimer's disease where we confirm that the disease is what we think it is but the proteins that build up in the brain, that is the way that we confirm diagnosis at pathology. we don't do that for everybody while they are alive. why those developing certain people and at what age is not clear yet. there may be environmental factors. there may be genetic risk factors and the actual genetic cause that confers 100% certainty of developing alzheimer's disease is very, very rare. typically that occurs at age 45. it is unusual in the general population. what we know is age is the biggest risk factor. there is genetic risk factors . education, good sleep, all of those factors play into a role of reducing the risk of alzheimer's too. >> for people who have been

diagnosed, what is the latest in alzheimer's therapy and treatments? the alzheimer -- the fda approved a drug that is proven to slow the decline in the early stages. are we getting closer to having a cure? how far away are we? >> it is really exciting news that we have this new therapy. it is targeted toward amyloid, one of the proteins that builds up in alzheimer's disease. is trying to remove amyloid. it develops in the brain 15 to 20 years before we have symptoms. that is why it is for people who only have early disease. people who are mild in their symptoms, but it is not for everybody. their risk factors, associated with getting any treatment, we are getting a lot closer. as we said, this treatment is not a cure . it is really only removing the amyloid and hopefully slowing down the progression. we are not seeing a removal of memory symptoms at all. we are getting so much closer than we have before but we really need to

continue to develop other therapies that may be targeting other proteins and other things we have yet to discover. >> there has been so much progress in the past five years. where do you see us in the next five years or 10 years? are we getting closer to curing it? >> so much closer. this is a time where we should be excited. we are not at the point of cure yet but in the next 10 years, we are getting closer to what we have seen in oncology or cancer treatment where we might say that you have this genetic risk, these types of metabolic factors, these blood tests and then we will have a better treatment. we are not yet there yet and we are treating all alzheimer's disease is the same. in the next 10 years, i think we can do blood tests, guidance of certain types of pet scans or mri scans and then help us figure out which drug is best for you. >> dr. sharon shaw of

stanford, thank you so much. still ahead, as we gear up for super bowl lviii, we are looking at some las vegas experiences to check out before the big game. see how this one takes you back in time.

looking live at allegiant stadium in vegas as we countdown to super bowl lviii right here on cbs . the 49ers

facing the chiefs. brock purdy will become the third youngest quarterback to ever start a super bowl. vern glenn takes a deep dive into the 49ers' qb one. >> this is the volkswagen red and gold report. >> while some members of the national keep waiting for brock purdy to fail, the quarterback keeps on winning and letting his play do the talking. >> i have never been the biggest, the fastest, the strongest or any of that. i have always had to fight for what i get and work for what i get. >> for the second straight week, purdy shook off a rough first half and played his best when it mattered most. he played 13 of 15 passes, ran for 49 yards. while he is not the type to respond to his critics, his teammates always have his back. >> we are lucky he is our quarterback. he takes a lot of heat for no reason. he has been a great leader, a great player.

>> brock has been brock for this entire season. he is the reason why we are going to the super bowl. he is the reason why we are in the nfc championship. we live and die with him. >> you guys have been questioned left and right. what do you say now? >> scoreboard. so proud of brock. i keep saying it. sooner or later, people will say it. as the niner faithful plan their trips to las vegas, there are some off the beaten path experiences that you cannot miss like this one. these dazzling displays are all part of the neon museum. it is dedicated to collecting and preserving iconic las vegas signs from the past. dozens of signs are on display outside of what the museum calls the neon boneyard. one couple who is in town for the super bowl says walking around the glowing neon feels like they're going back

in time. our reed cowin will be in las vegas for the super bowl. everyone has got their take on who will win the super bowl and by how much. we get the pr

you may know adam schiff's work to protect the rule of law, or to build affordable housing, or write california's patients bill of rights. but i know adam through the big brother program. we've been brothers since i was seven. he stood by my side as i graduated from yale, and i stood by his side when he married eve, the love of his life. i'm a little biased, but take it from adam's little brother.

he'll make us all proud as california senator. i'm adam schiff and i approve this message.
