How to react when facing a lightning hazard?

Around 25 million lightning strikes occur in the United States every year, with most taking place during the summer months. The NWS reports that these strikes result in about 20 fatalities annually. The probability of lightning strikes rises as a thunderstorm approaches and peaks when the storm is directly above. As the storm moves away, this likelihood decreases.

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 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 final lightning or thunder before heading outside again.

If finding indoor shelter is not an option:

• Stay away from open fields, hill summits, 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.
• Keep a distance from water, wet articles, and metal objects. While water and metal do not draw lightning, they are proficient conductors of electricity.

Rainy weather driving tips

• Turn on your headlights - Even when it's light outside, using headlights can improve visibility and alert other drivers to your presence.
• 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.
• Give ample space to large vehicles - Trucks or buses can create a water spray that diminishes 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 when a vehicle starts uncontrollably sliding 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.
