Published

on

While Hurricane Sally has been downgraded to a tropical depression, the slow moving storm still packs plenty of power to wreak some havoc on South Carolina today — with several inches of rain, flash flooding and even a few tornadoes threatening the Midlands and the Upstate today.

On Thursday morning, Sally‘s center was slowly creeping across eastern Alabama, while the storm system stretched all the way up the Carolinas, according to the National Hurricane Center.

Here’s a look at SC this morning:

Rain

Sally is expected to dump several inches of rain across the Midlands and Upstate, with lesser amounts in the Lowcountry.

The Midlands expects to see the most rain in South Carolina with 5-7 inches possible in some areas, and 4-6 inches in Columbia. Here’s a map showing total rainfall from the storm:

According to the NWS-Columbia, this amount of heavy rainfall throughout Thursday will likely lead to flash flooding across central South Carolina — especially across the Central Savannah River Area and western Midlands.

“Water may enter homes or businesses, especially in flood prone locations,” the NWS update said. “Small streams and creeks may rise
rapidly and overflow their banks.”

Here’s a map showing lesser amounts of rain in the Upsate, but significant enough to cause flash flooding in “urban areas, low-lying areas and
roads adjacent to streams,” likely to impact bridges and structures.

Tornadoes/ Wind

Isolated tornadoes are possible throughout Thursday afternoon in the Upstate and Midlands.

Forecasters predict maximum windgusts Thursday afternoon topping at around 22 MPH in Greenville and Columbia and 24 MPH in Augusta.

Wind is not expected to be a significant impact from this storm, NWS-Columbia officials said.
