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 becomes threatening and thunder can be heard, find a safe place to shelter.
• Once inside, avoid contact with 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, 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 with a group, fan out to stop the current from transmitting between 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.
• Stay away from water, wet items, and metal objects. Water and metal do not attract lightning but they are excellent conductors of electricity.

Rainy weather driving tips

• Turn on headlights - Even in daylight, using headlights can help improve visibility and let other drivers know where you are.
• 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.
• Maintain a safe distance from large vehicles - Trucks or buses can produce a water spray that hampers 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 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.
