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 suggestions for staying safe 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 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:

• Avoid open fields, the top of a hill, or a ridge top.
• Keep a distance from tall, solitary trees or other elevated structures. When in a forest, stay in proximity to shorter tree groupings.
• If you are with a group, fan out to stop the current from transmitting between members.
• 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.
• Keep a distance from water, wet articles, and metal objects. While water and metal do not draw lightning, they are proficient conductors of electricity.

What to do in the rain on the road?

• Switch on headlights - Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.
• While driving - Stick to the middle lanes and stay on elevated ground. Rainwater tends to accumulate at the road edges.
• Steer clear of puddles - Driving into puddles or low areas of rainwater can cause vehicles to hydroplane or skid out of control.
• Don't tail large vehicles closely - Trucks or buses can kick up a water spray that obstructs 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.
