A tornado watch issued Monday afternoon for Horry and Georgetown counties was canceled about 7 p.m., according to the National Weather Service in Wilmington, N.C.
Michael Caropolo, meteorologist with the NWS, said a warm front Monday morning brought increased moisture and assisted in destabilizing the atmosphere ahead of a cold front expected to push across the area Tuesday.
Strong gusty winds with gusts in excess of 60 mph, isolated tornadoes, small hail and heavy rain are possible from storms expected late Monday and early Tuesday, Caropolo said.
Storms are expected to reach the coast after 6 p.m. Monday bringing rainfall between three-quarters of an inch and 1.5 inches through Tuesday.
Isolated and possibly severe thunderstorms are likely after midnight with locally heavy rainfall and wind gusts up to 25 mph. Showers are likely into Tuesday morning with a slight chance of thunderstorms Tuesday afternoon. Temperatures in the lower 70s are expected Tuesday and rain chances continue throughout the day but will taper off into Wednesday. Clear skies are expected at the end of the work-week.
