An updated report was issued from the NWS Charleston SC on Thursday at 2:02 p.m. for strong thunderstorms until 2:30 p.m. The alert is for Inland Berkeley and Tidal Berkeley as well as Charleston County.

"At 2:02 p.m., Doppler radar tracked a line of strong thunderstorms extending from near Hampton Plantation State Park to near Wadmalaw Island, moving east at 20 mph," describes the NWS. "Gusty winds could knock down tree limbs and blow around unsecured objects."

Locations impacted by the alert include North Charleston, Mount Pleasant, Goose Creek, Hanahan, McClellanville, Daniel Island, Fort Sumter, Downtown Charleston, I-26/I-526 Interchange and James Island. This includes the following highways: I-26 between mile markers 213 and 221. I-526 between mile markers 11 and 31.

The NWS states, "Stay tuned to NOAA Weather Radio All Hazards, TV or your local news source for the latest information from the National Weather Service. Excessive cloud to ground lightning is occurring with these storms. Lightning can strike 15 miles away from a thunderstorm. Seek safe shelter inside a building or vehicle."

This alert is in effect until 2:30 p.m.

What to do as threat of lightning approaches?

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 tips on how to stay safe 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 inside, avoid contact with 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:

• Avoid open fields, hill peaks, or ridge tops.
• Stay away from tall, isolated trees or other tall objects. If you are in a forest, stay near a lower stand of trees.
• If you are with a group, fan out to stop the current from transmitting between members.
• If you are camping in an open space, choose a valley, ravine, or low area for your campsite. Remember, tents do not shield you from lightning.
• Do not approach water, wet objects, or metal items. Although water and metal do not attract lightning, they conduct electricity effectively.

Rainy weather driving tips

• Turn on your headlights - Even when it's light outside, using headlights can improve visibility and alert other drivers to your presence.
• While on the road - Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along the road edges.
• Keep clear of puddles - Driving through puddles or low rainwater areas can cause vehicles to hydroplane or skid out of control
• Give ample space to large vehicles - Trucks or buses can create a water spray that diminishes 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 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.
