Shielding yourself from approaching lightning: Expert safety guidelines

Lightning strikes the United States approximately 25 million times each year, with the bulk of these electrical discharges occurring during the summer months. Tragically, lightning claims the lives of about 20 individuals annually, as reported by the weather service. The risk of lightning-related incidents escalates as thunderstorms draw near, reaching its peak when the storm directly looms overhead. However, it gradually recedes as the tempest moves away.

To ensure your safety during a thunderstorm, keep these recommendations in mind:

1. Lightning safety plan:

  • When venturing outdoors, it's vital to establish a clear plan for seeking shelter in case of lightning.
  • Stay vigilant by monitoring the sky for ominous signs and listening for the telltale sound of thunder. If thunder is audible, it's a clear indication of nearby lightning.
  • Seek a safe place to shelter, preferably indoors.

2. Indoors safety measures:

  • Once you're indoors, avoid using corded phones, electrical devices, plumbing fixtures, and stay away from windows and doors.
  • These precautions help reduce the risk of electrical surges, as lightning can follow conductive pathways.

3. Wait for the all-clear:

  • After the last lightning strike or thunderclap, wait at least 30 minutes before resuming outdoor activities.
  • Lightning can strike even when a storm has seemingly passed, so exercise caution.

When indoor shelter isn't available:

If you find yourself outdoors with no access to indoor shelter during a thunderstorm, take these steps to maximize your safety:

  • Avoid open fields, hilltops, or ridge crests, as they expose you to greater lightning risk.
  • Steer clear of tall, isolated trees and other prominent objects. In wooded areas, stay close to lower stands of trees.
  • If you're in a group, ensure that individuals are spaced out to prevent lightning current from transferring between people.
  • Camping in an open setting during a thunderstorm is strongly discouraged. If you have no alternative, set up camp in a valley, ravine, or other low-lying areas. It's crucial to note that a tent provides no protection against lightning.
  • Do not approach water bodies, wet objects, or metal items. Although water and metal do not attract lightning, they conduct electricity effectively and can pose significant risks.

In summary, when facing the threat of lightning, vigilance and preparedness are your best allies. By following these guidelines, you can significantly reduce the chances of lightning-related accidents and prioritize your safety.

Navigating rainy roads: Safety tips for wet weather

Heavy rainfall may lead to flooding if prolonged or if there is excessive runoff. Excessive runoff can be a result of saturated ground and/or rainfall intensity. Follow these recommendations from the weather service to stay safe in heavy rain:

Beware of swollen waterways:

  • During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.

Maintain safe driving distances:

  • Adhere to the two-second rule for maintaining a safe following distance behind the vehicle in front of you. In heavy rain, allow an additional two seconds of distance to compensate for reduced traction and braking effectiveness.

Reduce speed and drive cautiously:

  • On wet roads, reducing your speed is crucial. Ease off the gas pedal gradually and avoid abrupt braking to prevent skidding.

Choose your lane wisely:

  • Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.

Visibility matters:

  • Enhance your visibility in heavy rain by turning on your headlights. Watch out for vehicles in blind spots, as rain-smeared windows can obscure them.

Watch out for slippery roads:

  • Be extra careful during the first half hour after rain begins. Grime and oil on the road surface mix with water to make the road slippery.

Keep a safe distance from large vehicles:

  • Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass them swiftly and safely.

Mind your windshield wipers:

  • Overloaded wiper blades can hinder visibility. If rain severely limits your sight, pull over and wait for conditions to improve. Seek refuge at rest areas or protected spots.
  • If the roadside is your only option, pull off as far as possible, preferably past the end of a guard rail, and wait until the storm passes. Keep your headlights on and turn on emergency flashers to alert other drivers of your position.

In the face of heavy rain, these precautions can make a significant difference in ensuring your safety on the road. Remember to stay informed about weather conditions and heed guidance from local authorities for a secure journey.
