Aiken, SC Issues Flash Flood Warning Amid Severe Thunderstorms
A flash flood warning has been issued for Aiken and Barnwell counties by the National Weather Service (NWS) Columbia SC on Saturday, effective until 3 p.m. The warning was prompted by severe thunderstorms producing heavy rainfall in the region, with Doppler radar indicating already fallen precipitation between 1.5 to 3 inches. Additional rainfall of 1 to 3 inches is anticipated, triggering ongoing flash flooding expected to begin shortly.
Areas most likely to experience flooding include Aiken, North Augusta, Barnwell, as well as notable locations such as the Savannah River Site, Aiken Mall, Clearwater, Belvedere, New Ellenton, and Jackson, among others. Highways at risk of flooding include portions of Interstate 520 and Interstate 20 between specific mile markers.
The NWS emphasizes that most flooding-related fatalities occur in vehicles and advises drivers to avoid traversing flooded roadways or circumventing barricades. Residents are urged to heed the cautionary advice: “turn around, don’t drown.” Those living in flood-prone areas should seek higher ground immediately.
Safety Instructions During Flash Flood Scenario
Evacuation is encouraged if authorities issue explicit instructions. Residents should lock their homes when leaving and disconnect utilities if time permits. Those in basements or rooms with submerged electrical outlets or cords should refrain from entering. Additionally, if unusual sounds or sparks are observed from electrical devices, evacuation is advised.
It is crucial to avoid contact with water that may conduct electricity and to stay clear of walking through floodwaters, which can be deceptively powerful; even 6 inches of moving water can knock an adult off their feet. In the event of being trapped by rising water, individuals should find the highest possible point for safety and contact emergency services at 911, if conditions allow.
The Risks of Flooding Explained
Heavy rain significantly raises the risk of flooding, particularly in low-lying areas susceptible to flooding. The NWS warns that as little as 12 inches of rapidly flowing water has the potential to sweep away most vehicles. Additionally, hydroplaning is a serious risk during these conditions, characterized by an uncontrollable slide of a vehicle on wet roads, caused by water pooling in front of tires, exceeding the weight that can be displaced by the vehicle. Past flood advisories confirm ongoing flooding concerns in the area.
Precautionary Measures for Residents
- Seek higher ground immediately.
- If instructed to evacuate, secure your home and utilities.
- Avoid walking through floodwaters and contact local authorities about flooding when safe.
- Stay updated on local weather conditions and heed instructions from emergency services.
This flood warning serves as a serious reminder of the inherent dangers of severe weather, necessitating immediate action from residents of Aiken and Barnwell counties.
