The hottest temperatures of the year will roast much of the East Coast on Monday as a flood threat goes out for the West from monsoonal moisture.
Heavy rain is possible over parts of the Southwest and Rockies over the next few days, which will cause additional flooding across the region.
Much of this heavy rain is due to the monsoonal flow, which is typical for this time of year.
Flood advisories, watches and warnings remain in effect from the Rockies to the Central Plains.
There’s also a front helping to enhance showers and thunderstorms across the region, adding to flooding problems.
Behind the front, some relief from the heat in terms of cooler temperatures for the central U.S.
