Violent thunderstorms will continue to threaten communities from Norfolk, Va., to Charleston, S.C., into this afternoon.
Damaging winds and downpours are the greatest dangers from the powerful thunderstorms targeting far southeastern Virginia and the eastern Carolinas.
The strength of the winds could lead to tree and structural damage. Falling trees bring additional damage and bodily harm risks depending on where they land. Meanwhile, downpours pose hazards to both residents and motorists.
Driving will become difficult as the heavy bursts of rain dramatically reduce visibility and cause water to pond on roadways, which heightens the risk of vehicles hydroplaning at highway speeds.
Low-lying and poor drainage areas are susceptible to flash flooding problems.
A few of the thunderstorms will drop hail, as one did earlier this morning north of Roanoke Rapids, N.C. Penny-sized hail fell.
The stage is also set for one or two tornadoes to touch down and cause destruction.
In addition to Norfolk and Charleston, other communities at risk for today's strong thunderstorms include Rocky Mount, Fayetteville and Wilmington, N.C., and Florence and Myrtle Beach, S.C.
