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 recommendations for maintaining safety during a thunderstorm:

• To reduce the chance of being struck by lightning, when venturing outside, have a plan to get to a safer area.

• If the sky becomes menacing and thunder becomes audible, seek out a safe place to seek shelter.

• Once indoors, avoid touching corded phones, electrical equipment, plumbing, and windows and doors.

• Wait for 30 minutes after the final lightning or thunder before heading outside again.

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, solitary trees or other elevated structures. When in a forest, stay in proximity to shorter tree groupings.

• When in a group, space out to prevent the current from transferring between individuals.

• 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.

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

• Give ample space to large vehicles — Trucks or buses can create a water spray that diminishes 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 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.
