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 tips on how to stay safe 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 inside, abstain from touching corded phones, electrical devices, 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.

• 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, disperse to prevent the current from passing between group members.

• 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.

• Keep a distance from water, wet articles, and metal objects. While water and metal do not draw lightning, they are proficient conductors of electricity.

What steps to follow when driving in the rain?

• Turn on headlights — Even in daylight, using headlights can help improve visibility and let other drivers know where you are.

• 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

• Maintain a safe distance from large vehicles — Trucks or buses can produce a water spray that hampers 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 happens when a vehicle starts 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.
