Severe Thunderstorms Expected in Charleston Area with High Winds and Heavy Rainfall
Charleston is bracing for severe thunderstorms today, with forecasts predicting high winds and heavy rainfall. The National Weather Service (NWS) issued a severe thunderstorm warning for Charleston County, effective until 8 p.m. local time. Residents are advised to prepare for wind gusts reaching up to 60 mph, along with heavy rain and potential flash flooding.
Daytime temperatures are expected to rise to a high of around 80°F, while overnight lows will drop to approximately 76°F. A chance of rain is significant, at 70%, with occasional heavy rainfall possible as the day progresses. Winds are anticipated to come from the southeast at speeds of 5 to 10 mph.
Severe thunderstorms have already been observed along a line stretching from Meggett to Kiawah Island, moving northeast at a speed of about 25 mph. Areas particularly at risk include Johns Island, West Ashley, James Island, Hollywood, Folly Beach, Ravenel, Seabrook Island, Kiawah Island, Meggett, and Rockville. With winds capable of damaging roofs, siding, and trees, residents are urged to seek shelter in sturdy structures during the storm.
Warnings from the NWS include considerable concerns about flash flooding resulting from torrential rainfall. Residents are cautioned not to drive through flooded roadways. Furthermore, it is advisable for individuals in the affected areas to report any storm damage once it is safe to do so by contacting the NWS at 888-383-2024.
The NWS alerts that summertime thunderstorms can lead to dangerous conditions. Statistics reveal that lightning strikes approximately 25 million times annually in the U.S., contributing to an average of 20 fatalities each year. Residents should note that if they can hear thunder, they are close enough to be struck by lightning.
In related news, the thunderstorms have already caused power outages, affecting nearly 3,000 customers of Dominion Energy and over 800 from Berkeley Electric Cooperative. Wind gusts have reached up to 55 mph, increasing the risk of further damage to properties and infrastructure. Cloud-to-ground lightning activity has also been reported continuously during storm conditions.
In addition to the primary warning, a special weather statement remains in effect regarding storm activity and potential hazards throughout the day. Afternoon showers are expected with a high temperature of around 81°F and a 60% chance of rain, with scattered thunderstorms anticipated to develop later in the night, maintaining a 40% chance of further rain.
Hydroplaning Risk
With wet conditions expected to persist, the risk of hydroplaning on roadways increases. Hydroplaning occurs when a vehicle loses control because of water buildup in front of its tires. Dangerous conditions can arise when factors such as speed, tire quality, and water depth interact negatively. Local drivers should stay vigilant and drive with caution during heavy rain.
Storm Preparation Recommendations
- Seek shelter inside a well-built structure during severe weather.
- Avoid windows and glass doors to minimize injury risk.
- Do not drive through flooded areas; turn around, don’t drown.
- Report any storm damage safely to local authorities.
