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 decrease the risk of getting struck by lightning, when you go outside, establish a plan to reach a safer place.
• If the sky becomes menacing and thunder becomes audible, seek out a safe place to seek shelter.
• Once inside, avoid contact with 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.
• Stay away from tall, isolated trees or other tall objects. If you are in a forest, stay near a lower stand of 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.
• Maintain a safe distance from water, wet items, and metal objects. Water and metal do not attract lightning, yet they conduct electricity efficiently.

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.
• 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.
• 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.
