Showers and drenching, locally gusty thunderstorms will focus in the South, central Plains and Southwest into Wednesday night, while a few storms will also ignite in the Northeast.
Atlanta; Charlotte, North Carolina; Richmond, Virginia; Columbia, South Carolina; Jackson, Mississippi; Monroe, Louisiana; and Texarkana, Arkansas, are among the Southern cities that will be hit by one or more thunderstorms into Wednesday night.
According to Senior Meteorologist Mark Mancuso, "The storms in the South will bring an elevated risk of flash flooding as some areas will be hit by multiple slow-moving downpours."
In addition to the risk of frequent flash flooding, the storms will can bring extensive travel delays as they hit major highways and airport hubs in the region. Some communities can be also hit by frequent lightning strikes and downed trees.
A few locally drenching showers and isolated strong thunderstorms are in the offing in the Northeast including from Washington, D.C., to Philadelphia, New York City and Boston.
Overall, the storms in the Northeast into Wednesday evening will be much less intense when compared to the storms from Tuesday. The bulk of the storms will occur during the late afternoon and evening hours in these areas and can bring brief disruptions to travel and outdoor activities.
Meanwhile, storms will erupt in portions of Nebraska, Kansas, Oklahoma and Texas as well.
The strongest storms will focus over Nebraska and Kansas, where there is the potential for large hail, damaging wind and a couple of tornadoes. Storms that erupt over Texas and Oklahoma will bring locally drenching rainfall.
As the Southwest Monsoon continues, thunderstorms that develop during the afternoon and evening hours will bring isolated incidents of flash flooding, gusty winds and blowing dust. The spotty storms are forecast over parts of Arizona, New Mexico, Utah, Nevada, Colorado and interior California, while heat builds over the Northwest.
It is never safe to attempt to drive through a flooded roadway. A foot of water can cause your vehicle to float. There is the chance the road surface may have been washed out beneath.
In the United States, 50 percent of flood fatalities are vehicle-related, according to FloodSafety.com.
