Actions to take when lightning threat is imminent

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 suggestions for staying 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 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 last lightning or thunder before going back out.

If finding indoor shelter is not an option:

• Avoid open fields, the top of a hill, or a ridge top.

• Avoid tall, isolated trees or other elevated objects. If you are in a forest, stick to areas with shorter tree cover.

• 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.

• Maintain a safe distance from water, wet items, and metal objects. Water and metal do not attract lightning, yet they conduct electricity efficiently.

What steps to follow when driving in the rain?

• Switch on headlights — Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.

• 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.

• Maintain a safe distance from large vehicles — Trucks or buses can produce a water spray that hampers 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. The three main causes of hydroplaning are:

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.
