Charleston, SC
An updated severe thunderstorm warning has been issued by the National Weather Service (NWS) in Charleston, SC, effective until 2 p.m. on Saturday. The warning encompasses both Dorchester and Charleston counties, with expected wind gusts approaching 50 mph.
At 1:30 p.m., Doppler radar indicated a strong thunderstorm near Magnolia Gardens, moving northwest at a speed of 15 mph. Residents in the affected regions should remain cautious as gusty winds from the storm could lead to tree limb damage and the displacement of unsecured outdoor objects.
The advisory specifically outlines several locations likely to be impacted by the storm, including:
- North Charleston
- West Ashley
- Johns Island
- Hollywood
- Ravenel
- Magnolia Gardens
- Red Top
- Rantowles
- Middleton Place
- Shadowmoss
Residents are encouraged to stay informed through NOAA Weather Radio All Hazards, local television, or news sources for the latest updates from the NWS.
According to statistics, approximately 25 million lightning strikes hit the U.S. each year, predominantly during the summer months. Tragically, annual lightning-related fatalities average around 20 individuals, a risk that increases significantly as thunderstorms approach, peaking when storms are overhead.
To ensure safety during thunderstorms, the NWS alert provides essential recommendations. One crucial safety concern involves hydroplaning, defined as the uncontrolled sliding of a vehicle when water accumulates underneath tires. Key factors contributing to this phenomenon include tire tread depth, speed, and water depth on roadways. Drivers are advised to be especially cautious under wet conditions to avoid accidents.
Further risk evaluations reveal ongoing severe storm threats in nearby counties. Recent observations indicate that the bulk of severe storms have moved out of the immediate area; nonetheless, isolated severe thunderstorms remain a possibility, leading to damaging winds that can cause significant harm to roofs, siding, and nearby trees.
Furthermore, storm damage reports and photographs can be submitted by residents to assist local authorities in addressing any issues stemming from the severe weather.
In relation to past alerts, it’s notable that the severe thunderstorm warning for Charleston, Berkeley, Dorchester, and Colleton counties officially expired at 10:45 a.m. on the same day. Previously, a tornado warning affecting Charleston, Colleton, and Beaufort counties was lifted shortly after 10 a.m.
