Charleston, SC Deals with Flash Floods: Heavy Rainfall Puts Residents on Alert
Oh, Charleston! The charming city known for its historic architecture and vibrant culture is facing a rather wet situation this weekend. The National Weather Service issued a Flash Flood Warning at 10:14 p.m. on Saturday, leaving residents bracing for some serious rainfall that could lead to flooding. This alert is set to remain effective until midnight Sunday, so it’s time to keep an eye out!
According to the latest updates, thunderstorms have unleashed a deluge, with rain amounts soaring between 3 and 5.5 inches in various parts of the city. Some weather stations, particularly those located in Folly Beach, Johns Island, and Wadmalaw Island, have reported soaking amounts of between 4.00-5.50 inches thus far. And if that wasn’t enough, forecasters are warning that we could see another 0.2 to 0.4 inches of rain as a cherry on top of this soaking cake!
As these heavy rains continue, flash flooding is not just a possibility – it’s currently happening or expected to commence shortly. While rainfall rates are starting to taper off a bit, key areas that experience the brunt of this weather are mostly along Main Road, Maybank Highway, River Road, Plow Ground Road, and Savannah Highway.
Areas Affected
If you are living in Johns Island, West Ashley, James Island, or places like Folly Beach, Ravenel, and even Kiawah Island, you’re right in the heart of the impacted zones. Flooding could potentially affect small creeks and streams, urban areas, highways, streets, underpasses, and other low-lying places. It’s safe to say that Charleston is in for a bumpy ride!
Safety Tips for Residents
Additionally, if you find yourself navigating floodwaters, do so with extreme caution. Even just 6 inches of swiftly moving water can knock you off your feet, and it’s scary to think that 12 inches of rushing water is enough to sweep away most vehicles! If you happen to get trapped in moving water, your best bet is to find the highest point possible and contact emergency services for assistance.
Changes in Flood Warnings
That being said, we can all agree that Charleston has seen a noticeable uptick in flash flooding events over the past 30 years. So gear up, stay dry, and keep safety the priority!
