At 3:55 p.m. on Wednesday, the NWS Blacksburg VA issued an updated severe thunderstorm warning in effect until 5 p.m. for Caswell County.

Wind gusts of up to 60 mph and quarter-sized hail (1 inch) are predicted.

"At 3:55 p.m., a severe thunderstorm was located near Aiken Summit, or near Axton, moving east at 10 mph," states the NWS. "Hail damage to vehicles is expected. Expect wind damage to roofs, siding, and trees."

Locations impacted by the warning include Danville, Chatham, Gretna, Ingram, Mt Airy, Providence and Blairs.

The NWS states, "Prepare immediately for large hail and damaging winds, as well as deadly cloud to ground lightning. For your safety, move to an interior room on the lowest floor of a sturdy building. Stay away from windows. Locally heavy rain will quickly reduce visibility and result in ponding of water on roadways, standing water in low lying areas, and minor flooding of creeks, streams, and areas of poor drainage. Drivers are urged to slow down and use extra caution to avoid hydroplaning."

This warning is in effect until 5 p.m.

How to react when facing a lightning hazard?

Around 25 million lightning strikes occur in the United States every year, with most taking place during the summer months. The NWS reports that these strikes result in about 20 fatalities annually. The probability of lightning strikes rises as a thunderstorm approaches and peaks when the storm is directly above. As the storm moves away, this likelihood decreases.

Here are recommendations for maintaining safety during a thunderstorm:

• To decrease the risk of getting struck by lightning, when you go outside, establish a plan to reach a safer place.
• If the sky grows ominous and you hear thunder, seek out a safe place to take 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:

• Avoid open fields, the top of a hill, or a ridge top.
• 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 space, choose a valley, ravine, or low area for your campsite. Remember, tents do not shield you from lightning.
• Stay away from water, wet items, and metal objects. Water and metal do not attract lightning but they are excellent conductors of electricity.

What steps to follow when driving in the rain?

• Turn on your headlights - Even when it's light outside, using headlights can improve visibility and alert other drivers to your presence.
• While driving - Stick to the middle lanes and stay on elevated ground. Rainwater tends to accumulate at the road edges.
• Keep clear of puddles - Driving through puddles or low rainwater areas can cause vehicles to hydroplane or skid out of control
• Do not follow large vehicles closely - Large vehicles like trucks or buses can create a spray of water that can reduce your visibility.
• Avoid flooded zones - If you encounter a flooded road, make a U-turn and go back. The powerful currents of flash floods can carry drivers off the road. Driving through deep water can also damage 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.
