What to do as threat of lightning approaches?

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 tips on how to stay safe 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 turns ominous and thunder can be heard, find a secure place for 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:

• Steer clear of open fields, hilltops, or ridge tops.
• Avoid tall, isolated trees or other elevated objects. If you are in a forest, stick to areas with shorter tree cover.
• When in a group, space out to prevent the current from transferring between individuals.
• If you are camping in an open space, choose a valley, ravine, or low area for your campsite. Remember, tents do not shield 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 to do in the rain on the road?

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