The NWS states, "Seek shelter inside a well-built structure and stay away from windows. These storms have produced damaging winds. Wind damage with these storms will occur before any rain or lightning. Do not wait for the sound of thunder before taking cover. Seek shelter immediately inside a sturdy structure and stay away from windows. Report severe weather to your nearest law enforcement agency or the National Weather Service office in Charleston SC."

This warning is in effect until 5:30 p.m.

Actions to take when lightning threat is imminent

Lightning hits the United States approximately 25 million times annually. The majority of these strikes happen during the summer, causing around 20 fatalities each year, according to the NWS. The likelihood of lightning increases as a thunderstorm gets closer and reaches its highest point when the storm is directly overhead. This risk decreases as the storm moves away.

Here are suggestions for staying safe during a thunderstorm:

• To lower the risk of lightning strikes, when going outdoors, develop a plan to reach a safer spot.
• If the sky turns ominous and thunder can be heard, find a secure place for shelter.
• Once indoors, avoid touching corded phones, electrical equipment, plumbing, and windows and doors.
• Wait for 30 minutes after the most recent lightning or thunder before venturing outside.

If finding indoor shelter is not an option:

• Stay away from open fields, hill summits, or ridge tops.
• Keep a distance from tall, isolated trees or other elevated objects. If in a forest, stay close to lower trees.
• If you are with a group, fan out to stop the current from transmitting between members.
• If you are camping in an open area, set up camp in a valley, ravine, or other low area. Remember, a tent offers no protection from lighting.
• Stay away from water, wet items, and metal objects. Water and metal do not attract lightning but they are excellent 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 driving - Stick to the middle lanes and stay on elevated ground. Rainwater tends to accumulate at the road edges.
• Avoid puddles - Driving into puddles or low rainwater areas can lead to vehicles hydroplaning or losing control.
• Do not follow large vehicles closely - Large vehicles like trucks or buses can create a spray of water that can reduce your 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 when a vehicle starts uncontrollably sliding 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 top three contributors to 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.
