The NWS Greenville-Spartanburg SC issued a weather alert at 4:47 p.m. on Monday for strong thunderstorms until 5:30 p.m. The alert is for Caldwell Mountains and Greater Caldwell as well as Alexander County.

Wind gusts of up to 50 mph and penny-sized hail (0.75 inches) are anticipated.

"At 4:47 p.m., Doppler radar tracked a strong thunderstorm 4 miles north of Lenoir, or near Cedar Rock, moving east at 35 mph," states the NWS. "Gusty winds could knock down tree limbs and blow around unsecured objects. Minor hail damage to outdoor objects is possible."

Locations impacted by the alert include Lenoir, Gamewell, Cedar Rock, Kings Creek, Globe, Vashti, Collettsville, Patterson, Upton and Edgemont.

According to the NWS, "If outdoors, consider seeking shelter inside a building."

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

Actions to take when lightning threat is imminent

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 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 inside, abstain from touching corded phones, electrical devices, plumbing, and windows and doors.
• Wait for 30 minutes after the last lightning or thunder before going back out.

If finding indoor shelter is not an option:

• Steer clear of open fields, hilltops, or ridge tops.
• Avoid tall, isolated trees or other elevated objects. If you are in a forest, stick to areas with shorter tree cover.
• If you are in a group, spread out to avoid the current traveling between group members.
• If you are camping in an open setting, set up camp in a valley, ravine, or other low spot. Bear in mind, a tent does not protect 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 to do in the rain on the road?

• Turn on your headlights - Even when it's light outside, using headlights can improve visibility and alert other drivers to your presence.
• On the road - Drive in the middle lanes and stay on high ground. Rainwater tends to stockpile on the edges of roads.
• 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.
• Avoid flooded areas - When encountering a flooded road, do a U-turn and head back. The strong currents from flash floods can pull drivers off roadways. Driving through deep water can also negatively affect a vehicle's mechanical and electrical systems.

What is hydroplaning?

Hydroplaning occurs when a vehicle begins to slide 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. Hydroplaning is primarily caused by three factors:

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.
