How to react when facing a lightning hazard?

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 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:

  • Stay away from open fields, hill summits, or ridge tops.
  • Avoid tall, isolated trees or other elevated objects. If you are in a forest, stick to areas with shorter tree cover.
  • If you are in a group, spread out to avoid the current traveling between group members.
  • 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.
  • Do not approach water, wet objects, or metal items. Although water and metal do not attract lightning, they conduct electricity effectively.

Rainy weather driving tips

  • Turn on headlights - Even in daylight, using headlights can help improve visibility and let other drivers know where you are.
  • While on the road - Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along 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.
  • Do not follow large vehicles closely - Large vehicles like trucks or buses can create a spray of water that can reduce your 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 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. 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.
