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 National Weather Service 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 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, 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.

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

• 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.

• 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 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. 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.
