Actions to take when lightning threat is imminent

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 decrease the risk of getting struck by lightning, when you go outside, establish a plan to reach 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 30 minutes after the last lightning or thunder before going back outside.

If finding indoor shelter is not an option:

• Avoid open fields, hill peaks, 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.
• 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.
• Do not approach water, wet objects, or metal items. Although water and metal do not attract lightning, they conduct electricity effectively.

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.
• Steer clear of puddles - Driving into puddles or low areas of rainwater 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. Hydroplaning is most commonly attributed to 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.
