In the wake of the complex of thunderstorms that hit the mid-Atlantic Thursday morning, the threat of tornadoes and widespread damaging wind continues from the mid-Atlantic to part of the South into Thursday evening.
Blazing sunshine heated the atmosphere to volatile levels in southern Virginia, southern Maryland, Delmarva, eastern Tennessee, North Carolina and parts of South Carolina and Georgia Thursday afternoon.
A squall line has developed and was moving swiftly southeastward with many incidents of downed trees and power outages. Some of the thunderstorms within the squall line were also capable of producing tornadoes.
Along and east of this squall line, there is an ongoing threat for brief tornadoes, frequent lightning strikes, powerful straight-line wind gusts, flash flooding and large hail.
At this time, the area of concern for damaging wind and a brief tornado stretches from Atlantic City, N.J. to Easton Md., Dover and Rehobeth Beach, Del., Norfolk, Va., to Raleigh and Elizabeth City, N.C., Florence and Myrtle Beach, S.C. and Atlanta, Ga.
The storms bring a risk of straight-line wind gusts of 60 to 80 mph.
Winds of this magnitude can knock down trees and cause power outages and significant property damage.
The overall pattern fits into the AccuWeather.com forecast for the summer of 2013, described earlier in May.
Remember if you can hear thunder, you are at risk for being struck by lightning. Move indoors, away from windows at the first sign of approaching storms. Do not attempt to drive through flooded roadways. Doing so puts not only you and other occupants at risk, but also your would-be rescuers.
