Every forecast across The Palmetto State, highway-clear.
Official National Weather Service forecasts for all 46 South Carolina counties — from the Upstate at Greenville and Spartanburg down I-26 through Columbia and the Midlands to Charleston, the Lowcountry, Hilton Head and the Grand Strand.
Every Carolinas region shares one system — the same maps, the same live radar, the same climate record. South Carolina sits where the Atlantic bends in, and it collects what the ocean sends. Hugo came ashore at Sullivan's Island, Matthew and the thousand-year flood of 2015 both parked over the Midlands, and the Lowcountry floods on a clear-sky king tide. Inland, the Upstate catches the tail of the southern Appalachians.
