Hurricane Helene brings dangerous winds, heavy rain, and tornado risks to South Carolina and Georgia.

Heavy Rain and Tornadoes Expected as Helene Targets Midlands

[COLUMBIA] — Issued by the National Weather Service at 5:24 AM EDT on September 26, 2024.

Hurricane Helene is set to impact the Midlands of South Carolina and the Central Savannah River Area (CSRA) of Georgia late tonight through Friday. A Tropical Storm Warning remains in effect, with conditions expected to deteriorate rapidly as the storm moves inland.

Significant Rainfall and Flooding to Impact Midlands

Helene is forecasted to bring heavy rain across the Midlands and CSRA, with rainfall totals reaching 3 to 5 inches and localized amounts exceeding 6 inches. Flash flooding is likely, particularly in low-lying areas and near rivers and creeks. Residents in flood-prone zones should prepare for possible evacuations.

Tornado Threat High South of I-20

The risk of tornadoes is substantial, especially south and east of the I-20 corridor. The greatest threat will be late Thursday into Friday morning. Tornadoes spawned by the outer bands of Helene could cause severe damage, power outages, and communication failures. Those in mobile homes or temporary shelters are advised to seek sturdier protection.

Damaging Winds Across the Midlands and CSRA

Winds of 15-25 mph with gusts up to 45 mph are expected in the Columbia area, while southern regions of the Midlands could see stronger gusts approaching tropical storm force. These winds could result in damage to porches, trees, and power lines, leading to scattered outages. Road conditions will be hazardous, particularly on bridges and elevated roadways.

Flooding Rain Threatens South Carolina Rivers

The heavy rainfall will stress local rivers and tributaries, with the potential for significant flooding. The region’s flood control systems may struggle to manage the high water levels, increasing the risk of overflow and inundation in adjacent communities. Rapidly rising waters can be deadly—avoid driving through flooded areas and move to higher ground if necessary.
