McCormick, South Carolina Faces Flash Flooding Threat

The National Weather Service has issued a Flash Flood Warning for Central McCormick County in South Carolina, effective from Tuesday, August 5, at 6:38 AM EDT until 8:30 AM EDT. The warning comes as heavy rainfall has already impacted the region, with Doppler radar and automated rain gauges registering rainfall amounts between 2 and 2.5 inches. Flash flooding is either currently ongoing or is expected to begin shortly.

Residents in the affected areas can expect additional rainfall rates of between 0.5 to 1 inch per hour, with total precipitation potentially reaching 1 to 2 inches beyond the current levels. This significant rainfall poses a serious risk of flash flooding in various locations, including small creeks, urban environments, highways, streets, underpasses, and other areas with poor drainage or low-lying topography.

Areas at Risk

Specific locations forecasted to experience flash flooding include McCormick, McCormick County Airport, Plum Branch, Whitetown, and Hawe Creek Campground. With the anticipated rainfall, not only will roads be affected, but there is also a possibility of minor flooding in low-lying areas that typically struggle with drainage issues.

Driving Safety Concerns

Authorities emphasize the dangers associated with flooding, advising residents that most flood-related deaths occur in vehicles. Individuals are urged not to drive through flooded roadways or around barricades. The simple reminder of “turn around, don’t drown” is critical for ensuring safety during this hazardous weather situation.

Additional Weather Advisories

A Flood Advisory is also in effect for portions of east-central Georgia, including Lincoln County and central South Carolina (McCormick), until 7:45 AM EDT. This advisory supports the existing flash flood warning, with expectations of minor flooding due to excessive rainfall and an additional anticipated 1 to 2 inches.

Similar locations under this threat include areas such as Knox Scout Reservation, Double Branches, New Hope, Cherokee Boat Ramp, and other sites recognized for poor drainage. Communities are strongly encouraged to prepare for potential impacts and take necessary precautions.

Previous Warnings

Earlier today, a similar Flash Flood Warning had been issued for Eastern Abbeville County and Northwestern Greenwood County, with reports of 2 to 3.5 inches of rain recorded since 3 AM. This ongoing weather event points to the severity of conditions in the region and contributes to the overall risk of flooding.

Continued Monitoring

A Flood Watch remains in effect until 8:00 PM EDT for portions of central and northeast Georgia. This watch highlights the ongoing risk of flooding, considering expected rainfall quantities and saturated soil conditions. Authorities have stated that excessive runoff could significantly flood nearby rivers and streams, leading to the potential for major flooding in certain locations.

Residents are encouraged to stay informed and remain vigilant as the rainfall continues. Precautious measures should be taken to safeguard homes and properties from potential water damage, and regular updates should be monitored from reliable weather sources as conditions evolve.
