rebecca stevenson joining us very intense storms and not over yet. >> stretching across the northeast, lit up with lightning on the east coast. but it is the southwest that we've got big concerns because we're tracking hurricane norbert here. hurricane norbert went from a category 3 early in the morning down to a category 1 now and it's pumping up so much moisture into arizona and new mexico, near record moisture in the air. you can see from the video already what kind of damage that this has caused all along the mexico coastline. we have had a lot of flooding here, a lot of beach erosion too, but the flood concerns turned into flash flooding in places a little further inland. because it's a number of thunderstorms that are whipping through with wind damage. we've had a lot of folks coming in and getting some rest accuse from this particular hurricane. which has not moved onshore. it has just been spinning bands of very, very heavy rainfall and strong gusty winds right across the baja peninsula. now it will continue its track up towards the north but as it turns inland it's not going

. >> rebecca stevenson is here with more of your weather. lot going on. >> yes, the hurricanes, tropical tomorro storms. the first, odile, still lingering around the south-west, from texas to nevada. and so much moisture is hanging in the air that once the showers and thunder storms roll through, it doesn't take much to lift it up and bring 2-4 inches of rainfall quickly. within a matter of hours. as we look closely here, you see the showers, thunder storms, and the rain rates up to an inch and a half per hour. that's how much water is coming down in this large area. we total up the rain fall. corpus kristi, 2.5 inches of rain, and we are accumulating it now into west texas and parts of south-east new mexico. that's where flash floods are in effect and flash flood watches. that stretches up through nevada, and comes close to the california border. it would be great to get rain fall popping up around the copying fire, the wildfire. we are not seeing that at this point. we are getting gusty winds. that's what we have here. 30-40 miles per hour

. >>> rebecca stevenson is here with the latest. rebecca. >> we watched really heavy rainfall pass through, half an irch evere inch o -- half an inf rain in an hour. continuing philadelphia to washington, d.c. as well. the rain totals last 24 hours are impressive. not just for new york city at half an inch but for philadelphia, coming in over an inch and quarter of an inch for d.c. in the last few hours. midwest is where our strongest most powerful storms have pen with. heaviest rains stretching kansas iowa, we have seen that area being watched become smaller but look at all the hail and wind reports. we've had a lot of flash flooding going on with the storm system and winds, we are still clocking wind gusts at 51 miles an hour in central iowa, around des moines, and storms bringing blustery winds around oklahoma as well. the storms are going to slowly ease a little bit. we still have to keep an eye to the sky even overnight. because look at how cold that air is behind this front. dropped 23° from the same time last night in rapid ci

rebecca stevenson is here. >> hitting record high in all parts of southern california.in fact, three areas reported record highs, near el cajon, yesterday it was 100, today it was 99. we also had it around laguna beach and a few other areas further south and into parts of arizona as well. hot weather, we have got hot weather advisories, so dry and you've got those gusty east winds, several places, all the way up the west coast, we've been dealing with smoke drifting in the air from the easterly, southeasterly winds. even into nevada and into western washington and oregon, 80s and 90s. this is up to 15 degrees above the normal this time of the year. where if you just head east of the rockies, ten to 15° below the normal for this time of year. so it's quite chilly for places around thunder bay, minneapolis and chicago, and going to stay on the cooler side. the morning hours will start off with one of the first profits in the season, around the great lakes and maine, it will be chilly into the low to mid 30s for you to start the day. but the biggest heat energy system that

rebecca stevenson joins us. >> it is tracking away from the baja peninsula, you can see it highlighted here. the high cloud tops in light green you can see them fade off to the west because it is starting to slowly, slowly, so slowly, can i say that one more time, how slow polo is falling apart? we are going to see rainfall still impacting part of the baja peninsula but it is the moisture we are watching, because of that moisture from not only tropical storm polo but hurricane odile all those days ago, churning up showers and thunderstorms that are so heavy. water in the atmosphere up to inch and a half to two inches hanging in the air waiting for a storm to push it up so it pripts precipitates down. causing problems into texas as well. it's so remarkable how much water is hanging in the atmosphere that we're seeing amounts for late september it's well above average. that's why we've got this heavy amount of rainfall coming down in such a dry area that's been dealing with drought all summer long. you can see on our hazards here we have high flood warning impacting nevada but also impac

meteorologist rebecca stevenson has that part of the story. >> when we talk about how to address climate change, let's talk about weather, day-to-day forecasts, how it impacts us. many tiles we look at the rain, but more often we look at much smaller scale forecasts. if you live in florida, you want to know where the heavy rain will hit. this day tomorrow, around tampa and tampa bay, lighter scattered showers elsewhere. president obama's addressing climate change, and asking us to develop a strategic plan, bringing into partnership government agencies, and we see them bringing together data, detailed maps. they'll train nations, how to use them, to send out warnings to clear out of the areas where natural disaster could occur. rather than getting a 3-day warning to evacuate, you'll get an 8-day warning. that's the goal. we look at 90 meter of revolution around the niger river delta. what we have now is fuzzy. we go to the recent release. africa is the first nation included, and will be used to have a better tell - high elevation to low elevation. that will give you a better idea of where

for the latest on the forecast rebecca stevenson joins us. >> it hasn't lost strength. it's 40 miles per hour, but in 24 hours, like you said, i think it will die off. it's heading to the west and will be falling apart. we have seen a lot of thunder storms circulating around the center die off. there hasn't been as many. it's becoming a confirmed forecast that this is going to move out of the picture. the moisture that is within this storm, and the moisture that was from the old hurricane odile is impacting the south-west, bringing flooding, rain fall throughout the night and we have seen incredibly heavy amounts of rain - 2-4 inches in short periods of time. what is most notable about this particular set up is that many of the service office forecasters is looking at the amount of moisture on the air, it's anywhere from 1.5 to 2 inches, it's near the highest percentage they have seen in late september. incredible amount of rainfall brought out by lifting up the air, and all the moisture. it will come down fast. the totals here impressive. salt lake city, you had a roug

rebecca stevenson has that and the rest of the forecast coming up on al jazeera america. >>> firefighters stopped the spread of a wildfire that covered 250 acres in northern california. dozens of families had to leave their homes, the evacuation orders have been lifted. two dozen homes have been damaged by the flames, and there's two square miles. that fire is 20% contained this afternoon. >>> united states has two extremes on one side, one 15 degrees normal, 15 degrees cooler than normal. record heat in california. temperatures soaring into the upper 90s, a record set for canmario, san berg and other areas 100 degrees. warnings and advisories continuing for the heat tomorrow. it's not going anywhere soon, it's hot, dry, windy. and soaring into the north-west. tracking up to seattle, and in to vancouver. you can see the heat, but the dry, hot windy conditions are a big concern for fire starts. we are so tinter dry here that all you need is the bark. we are watching closely. across the rockies, temperatures 15 below normal. it was a chilly start for the folks at the canadian border. in okl

. >>> rebecca stevenson joins us for a look at the forecast. it mays a factor? >> you talked of steep terrain and the drought. tomorrow and tonight flash flooding into california, arizona, utah and nevada. there's a lot of water coming up. the south-west used to having monsoon season, but now the moisture is coming not so much because of monsoonal wind, but because of an old hurricane that is falling apart. it's no longer a hurricane, it's a tropical storm getting weaker, but is sending record amounts of moisture into the atmosphere so by the time we get a storm, it dumps out 2 inches of rain. this will continue as we get through the next two days, until timely the storm system's moisture works eastward to the south. north, it's a different story, because fall is knocking on the door. september 22nd, officials start. snow coming down in the british columbia mount ans, it's like moisture coming off the pacific, slamming into a cool air mass. we'll get several inches of snow. it will stretch down by tomorrow night into the north-east rockies. it looks like most of

rebecca stevenson is here to tell us just how close we're going to get. >> some folks get to see it ande don't. it of course depends on the weather. first what i want to show you is what we had february 15, 2013 over russia. listen to this. you can see it, it caused a lot of damage, listen to some of the damage this massive asteroid caused when it hit the earth's atmosphere. car alarms went off, windows shattered, 15,000 injuries reported with this, as the asteroid blasted into earth's atmosphere, it was undetected by nasa. nasa is watching 11 million asteroids usually between mars and jupiter. now, we've been watching this particular asteroid, because it didn't become detected until last week. in fact, the size of it, it's only the size of a 60-foot house, so really in the scheme of things, it's not that big, but what's interesting is how close it will come to earth. the moon on average is about 239,000 miles away from the earth, but the asteroid is going to pass closer, 23 million miles -- 23 -- got to get those numbers straight. it is the sheer size, massive, yet looks so little. whe
