Transcript for September Weather Starts Off With Summer Heat
Massive storms on both coasts, flash flooding trapping drivers. Abc meteorologist ginger zee with the pictures and the forecast for the millions hitting the roads to return home after the holiday weekend tomorrow. Reporter: Holiday weekend washout. In boston, flash flooding closing highways. Up to three inches of rain falling in less than two hours. And more than 2,500 miles west, at least a dozen water rescues. Watch as this car plows into the muddy flood water in california. The driver getting out just in time as wave after wave buries his car. Severe storms smothering the midwest. Dropping tennis ball-sized hail in south dakota and a tornado in north dakota. And ginger zee is with us now. And ginger, tomorrow, millions will be back on the road returning home from their labor day weekend and it's going to be very dangerous. Reporter: Right. Unsettled for so many. I want to show you who and how much. We're talking rain, and it will be scattered, so, this is not an all-day rain everywhere. But in blue, that's up to a half inch of rain and some of the areas in new england getting more than an inch. Something to watch for. So, give yourself a lot of time to get to where you are going. Out west, the danger remains, too, with the flash flooding there which has been deadly. Reporter: Right. And this has been weeks on end that we've had this. Very different for them. We still have flood watches and warnings for several states out in the west and close to the pacific northwest. I also want to tell you why this is happening. And why it's not going to stop. You have that high pressure system, it's pumping moisture, it rotates clockwise, so the back side pumps moisture right up against that stationary front. It gets stuck and you get flash flooding.
