What to do as threat of lightning approaches?

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 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 indoors, avoid touching corded phones, electrical equipment, plumbing, and windows and doors.
• Wait 30 minutes after the last lightning or thunder before going back 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.
• When in a group, space out to prevent the current from transferring between individuals.
• When camping in an open environment, select a campsite in a valley, ravine, or low region. Just remember, tents do not offer protection 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

• Switch on headlights - Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.
• While on the road - Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along the road edges.
• Keep clear of puddles - Driving through puddles or low rainwater areas 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.
• 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 occurs when a vehicle begins to slide 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.
