On Tuesday at 3:17 p.m. an updated severe thunderstorm warning was released by the NWS Charleston SC in effect until 3:45 p.m. for Charleston County.

Residents should prepare for wind gusts of up to 60 mph.

"At 3:17 p.m., severe thunderstorms were located along a line from 10 miles northeast of Santee Coastal Reserve to 6 miles west of McClellanville, moving east at 15 mph," describes the NWS. "Expect damage to roofs, siding, and trees."

Locations impacted by the warning include McClellanville, Awendaw, Lighthouse Island, Hampton Plantation State Park, Cape Romain, Santee Coastal Reserve, Cape Island, Tibwin, Buck Hall and South Santee.

The NWS comments, "Seek shelter inside a well-built structure and stay away from windows. These storms are capable of producing damaging winds. Continuous cloud to ground lightning is occurring with these storms. Lightning is one of nature's leading killers. Remember, if you can hear thunder, you are close enough to be struck by lightning."

This warning is in effect until 3:45 p.m.

How to react when facing a lightning hazard?

Lightning strikes the United States about 25 million times a year. Most of the strikes occur in the summer, killing 20 people each year, according to the NWS. Chance of lightning increases as a thunderstorm approaches and peaks when the storm is overhead. It diminishes as the storm moves away.

Here are recommendations for maintaining safety during a thunderstorm:

• To minimize risk of being struck by lightning, when going outside, have a plan to get to a safer place.
• If the sky becomes threatening and thunder can be heard, find a safe place to shelter.
• Once indoors, avoid touching corded phones, electrical equipment, plumbing, and windows and doors.
• Wait for 30 minutes after the final lightning or thunder before heading outside again.

If finding indoor shelter is not an option:

• Avoid open fields, the top of a hill, or a ridge top.
• Keep a distance from tall, solitary trees or other elevated structures. When in a forest, stay in proximity to shorter tree groupings.
• When in a group, space out to prevent the current from transferring between individuals.
• When camping in an open environment, select a campsite in a valley, ravine, or low region. Just remember, tents do not offer protection from lightning.
• Keep a distance from water, wet articles, and metal objects. While water and metal do not draw lightning, they are proficient conductors of electricity.

Rainy weather driving tips

• Turn on headlights - Even in daylight, using headlights can help improve visibility and let other drivers know where you are.
• While on the road - Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along the road edges.
• Avoid puddles - Driving into puddles or low rainwater areas can lead to vehicles hydroplaning or losing control.
• Maintain a safe distance from large vehicles - Trucks or buses can produce a water spray that hampers visibility.
• Steer clear of flooded areas - When coming to a flooded road, turn around and head back. Flash flooding currents are strong and can sweep drivers off roadways. Driving through deep water can also affect a vehicle's mechanical and electrical systems.

What is hydroplaning?

Hydroplaning is the term for when a vehicle begins sliding uncontrollably on wet roads.

This happens when water in front of the tire builds up faster than the vehicle's weight can push water out of the way. The water pressure then causes the vehicle to rise and slide on a thin layer of water between the tires and the road, making the driver lose control. The three main causes of hydroplaning are:

1. Vehicle speed - When a vehicle's speed increases, the tire-traction grip and ability to control the vehicle decreases. Drive at a reduced speed during wet weather.
2. Water depth - The deeper the water, the sooner a vehicle loses traction on the road. It doesn't matter how deep the water is, even a thin layer can lead to hydroplaning.
3. Tire tread depth - Checking your tire tread before hitting the road is important, as low or no tread can lead to sliding.

In the event of your vehicle hydroplaning, here's what to know:

• Ease off the accelerator - Step off the gas to slow down the vehicle until the tires find traction.
• Turn into the skid - Turning into the skid can help the vehicle's tires realign to regain control.
• Make sure the tires reconnect with the road - During the skid, wait until the tires reconnect with the road and then gently straighten the wheels to regain control.
• Brake gently as needed - Brake normally if the vehicle has anti-lock brakes and pump brakes gently if in an older vehicle.
