Thunderstorms with strong winds will threaten lives and property in parts of the eastern United States into Wednesday evening.
The greatest risk of thunderstorms with gusts between 40 and 60 mph will extend from southeastern Louisiana to the western part of the Florida Panhandle, northward to western and central North Carolina.
People in these areas should seek shelter as the storms approach.
The storms will not be as intense as those which struck areas from Louisiana to Alabama and Tennessee on Tuesday, according to AccuWeather Senior Meteorologist Henry Margusity.
Storms from late Tuesday afternoon through Tuesday night were fatal in some communities. The storms generated more than 100 severe weather incidents, including more than two dozen reports of tornadoes.
"Winds can be strong enough to knock down trees and large tree limbs and cause property damage into Wednesday evening," Margusity said.
A couple of the strongest storms could also produce a brief tornado.
The most far-reaching impact of the storms will be downpours that can lead to urban and poor drainage area flooding.
Some of the downpours as far to the northeast as New York state and New England can be accompanied by brief gusty winds.
The sudden downpours and wind can blind some motorists and cause low enough visibility to lead to brief airline delays at the major hubs from Atlanta and Charlotte, North Carolina, to Washington, D.C., Philadelphia, New York City and Boston.
People heading to Rockefeller Center in New York City for the tree lighting during Wednesday evening should be prepared for wet but mild conditions.
During Wednesday night and Thursday, from west to east, a push of drier and chillier air will arrive and sweep clouds and storms away from much of the Appalachians and the Atlantic and Gulf coasts.
