Severe Thunderstorm Warnings Hit Charleston County!

Charleston, South Carolina, is in for a wild ride as the National Weather Service has issued a serious severe thunderstorm warning at 7:49 p.m. on a Tuesday evening. This warning is in effect until 8 p.m. tonight, and it’s time for residents to take it seriously!

What to Expect

Get ready for some intense weather folks, as residents should brace themselves for wind gusts of up to 60 mph. These gusts can turn a calm evening into a chaotic night in no time! The storms are currently moving northeast at about 25 mph and are reported as active along a line from Meggett to near Kiawah Island.

Those living in affected areas, such as Johns Island, West Ashley, James Island, Hollywood, Folly Beach, Ravenel, Seabrook Island, Kiawah Island, Meggett, and Rockville, should be on high alert! This storm system has a reputation for packing some punch and could lead to damage to roofs, siding, and even trees.

Safety Precautions

Now is the time to make a safety plan! Residents are advised to *seek shelter indoors* and **avoid windows** as the threat of damaging winds rises. With torrential rain accompanying the storm, there’s also a high risk of flash flooding. If you’re out and about, remember: never drive through flooded roadways. Your safety comes first!

Lightning Strikes: A Serious Concern

On top of everything, keep in mind that thunderstorms bring increased lightning strikes. In the U.S. alone, around 25 million lightning strikes happen each year, especially during summer. On average, this results in about 20 fatalities annually. So, as the storm approaches, stay indoors and keep safe.

Hydroplaning: Know the Risks!

If you do have to go out during this storm, be cautious! Hydroplaning can be a risk when the roads get slick. It’s when your vehicle slides uncontrollably over a layer of water that builds up under your tires. Understanding this danger is key in keeping safe on the road!

Earlier Alerts

It’s also worth mentioning that an earlier severe weather alert was issued for parts of Charleston County until 4:15 p.m., warning of similar conditions, including wind gusts of up to 60 mph and the potential for some pea-sized hail. So, it seems the weather gods are not being too kind to Charleston lately!

Stay Safe, Charleston!

As the storm nears, take every precaution necessary to ensure the safety of yourselves and your loved ones. Remember to report any storm damage to the Charleston NWS at 888-383-2024 when it’s safe to do so. Nature can be unpredictable, but with awareness and preparation, we can face whatever Mother Nature throws our way!
