COLUMBIA, S.C. (WIS) – Tropical showers and gusty winds continue tonight as Tropical Storm Idalia moves along the South Carolina coast. Rain will end overnight with winds dying down as Idalia moves out into the Atlantic.

First Alert Headlines

· Tropical showers and gusty winds continue tonight.

· Rainfall totals between 2-6″ leading to isolated flooding tonight.

· Drier weather arrives tomorrow and will last for several days setting up a beautiful Labor Day weekend.

First Alert Summary


For tonight steady showers will continue across much of the Midlands leading to some flooding as most of the region will receive between 2-6 inches of rain.

We will also encounter some very gusty winds up to 50 mph in spots, even higher closer to the coast, which could knock down tree, especially with the ground soaked.

Areas of Coastal South Carolina could see a storm surge greater than 3 feet tonight. With the king tide kicking in we see that increase to around 5 feet especially around Hilton Head, Beaufort, and Charleston.

After midnight and into the overnight hours the rain and winds will die down as the center of Idalia moves out into the Atlantic.


As Idalia slides out into the Atlantic on Thursday a cold front will sweep down over the Midlands pulling down some sun and drier weather.

Thursday and Friday look really nice with mostly sunny skies and highs in the lower to mid 80s with low humidity creating great weather to help the region dry out.

High pressure will then build over the Carolinas for the Labor Day weekend creating bright and mainly sunny days all weekend long, but it will get hotter again with highs topping out in the upper 80s to near 90 by Labor Day.

The high pressure will continue to dominate our weather much of next week creating more sunny and dry days with highs in the lower 90s.
