When lightning looms: Expert safety tips for thunderstorms

Each year, lightning strikes the United States approximately 25 million times, mostly during the summer. It claims the lives of about 20 people annually, according to the NWS. The threat of lightning becomes more pronounced as thunderstorms draw nearer, peaking when the storm is directly overhead and gradually waning as it moves away.

To ensure your safety during a thunderstorm, consider 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 a safe place to shelter, 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, which 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 with a group, ensure individuals are spread 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. 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, 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 rainy roads: Safety tips for wet weather

Rain can turn roads into hazards. Stay informed and follow these tips from the NWS to ensure safety during heavy rainfall:

Beware of rapid water flow:

In heavy rain, refrain from parking or walking near culverts or drainage ditches, where swift-moving water can pose a grave danger.

Maintain safe driving distances:

The two-second rule for following distance is your ally in heavy rain. Extend it to four seconds to ensure safe spacing in adverse conditions.

Slow down and stay cautious:

On wet roads, reducing your speed is crucial. Ease off the accelerator 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:

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:

The initial half-hour of rain is when roads are slickest due to a mixture of rain, grime, and oil. Exercise heightened caution during this period.

Keep a safe distance from large vehicles:

Large trucks and buses can reduce your visibility with tire spray. Avoid tailgating and pass with caution.

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.
