Along the Gulf Coast, warm, moist air contributes to the threat of severe storms, including strong tornadoes and damaging winds.
Severe Storm Threat and Flooding Concerns
More than 15 million people face a severe storm threat from Texas to Florida on Monday.
An estimated 35 million under the same threat on Tuesday from the Florida Panhandle to the Outer Banks of North Carolina.
Widespread river and flash flooding are anticipated from the central Gulf Coast through much of the Eastern U.S. Rainfall totals of 1 to 3 inches, with isolated locations exceeding 4 inches, are expected from the Gulf Coast to New England.
Flood Risk and Snowmelt in the Northeast
The Northeast, still recovering from the previous snowstorm, faces a Level 3 out of 4 risks for flooding in parts of New Jersey, New York, and Pennsylvania on Tuesday.
Heavy rain exacerbates snowmelt, raising flood potential. Wind adds to concerns, making trees susceptible to toppling, potentially causing power outages.
High Winds South and East
Louisiana and Mississippi, dealing with droughts, face potential flooding due to the saturated ground. Winds exceeding 50 MPH may cause damage from the Appalachians to the East Coast.
