Rounds of heavy rains to continue on Monday across South Carolina

Heavy rain will continue to fall across South Carolina at the beginning of the week. Periods of heavy rain will continue to stream mainly south to north as a low-pressure system passes just to our west. The positioning of this low-pressure system is pulling lots of deep tropical moisture across the Palmetto State, which will stay producing the chance for flash floods throughout the day. Some showers will still linger around on Tuesday; therefore, a few spots may develop flooding again.

Overall, we expect higher rainfall across Upstate and the Lowcountry. Across Upstate South Carolina, the rainfall will range between 2 and 4 inches, with some spots that could receive up to 5 inches isolated. Across the Lowcountry, rain totals will range between 2 and 4 inches, with some isolated spots accumulating up to 5 inches. The Midlands and the Pee Dee rainfall will vary between 1 and 3 inches. Some models hint at rain in the higher range across the northern portions of the Midlands.

Please avoid flooded roads. Remember, don’t drown. Six inches of water could cause your vehicle to stall, while six inches of standing water could cause it to float.

This rainfall could significantly reduce drought levels across South Carolina, especially along the coast. The next drought monitor update will be released on Thursday morning. We expect to see a big difference, as we’ve had a very slow-moving low-pressure system and a stationary front that has meandered and brought several rounds of rain since last Friday.

Expect the weather to improve by mid-week, with drier conditions across the state. Temperatures will remain slightly above normal for this time of year as a high-pressure system will be located to our east. By the end of the week, temperatures could reach the 90s statewide.
