How to react when facing a lightning hazard?

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 minimize risk of being struck by lightning, when going outside, have a plan to get to a safer place.

• If the sky turns ominous and thunder can be heard, find a secure place for shelter.

• Once indoors, avoid touching corded phones, electrical equipment, 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:

• 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.

• 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 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 on the road — Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along the road edges.

• Avoid puddles — Driving into puddles or low rainwater areas can lead to vehicles hydroplaning or losing control.

• Don't tail large vehicles closely — Trucks or buses can kick up a water spray that obstructs 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 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.
