Staying safe as lightning approaches: Expert advice

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 NWS. 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 guarantee your safety in the midst of a thunderstorm, take into account the following recommendations:

Lightning safety plan:

• When venturing outdoors, it’s crucial to have a lightning safety plan in place.

• Monitor the sky for threatening signs and listen for the sound of thunder. If thunder is audible, it’s an indication that lightning is nearby.

• Seek shelter promptly in a safe location, preferably indoors.

Indoors safety measures:

• Once you’ve found shelter indoors, abstain from using corded phones, electrical appliances, or plumbing fixtures, and refrain from approaching windows and doors.

• Lightning can follow conductive pathways, and these precautions reduce the risk of electrical surges.

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 without 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 forested 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 no alternative exists, set up camp in a valley, ravine, or other low-lying areas. Remember that a tent offers no protection against lightning.

• Do not approach water bodies, wet objects, or metal items. While water and metal don’t attract lightning, they conduct electricity effectively and can pose significant risks.

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

Navigating heavy rain: Essential safety measures for wet roads

When heavy rain pours, the risk of flooding and treacherous roads rises. Here’s your guide from the NWS to staying safe during downpours:

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, slowing down is paramount. Gradually ease off the accelerator and avoid abrupt braking to prevent skidding.

Choose your lane wisely:

Stay toward the middle lanes – water tends to pool in the outside lanes.

Visibility matters:

Turn on your headlights and be careful of other vehicles to the rear and in blind spot areas as they are especially difficult to see through rain-spattered windows.

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 impairs your vision, pull over and wait for conditions to improve. Seek refuge at rest areas or sheltered 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.
