When lightning looms: Expert safety tips for thunderstorms

Each year, lightning strikes the United States approximately 25 million times, with the majority of these electrifying events occurring during the summer months. Unfortunately, lightning is responsible for claiming the lives of approximately 20 people annually, as reported by 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, keep these recommendations in mind:

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 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.

• It’s important to remember that lightning can strike even when a storm seems to have 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 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 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, 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.

Rainy roadways ahead: Essential safety tips for heavy rain

When heavy rain sets in, the risk of flooding and hazardous driving conditions rises. Whether it’s prolonged rainfall or rapid runoff, being prepared is essential. Here are some valuable safety tips from the NWS to ensure you stay safe in heavy rain:

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.

Reduce speed and drive cautiously:

If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.

Choose your lane wisely:

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

Prioritize visibility

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

Keep a safe distance from large vehicles:

Don’t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Take care when passing them as well; if you must pass, do so quickly 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.

When stopping by the roadside is your only option, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate emergency flashers to alert other drivers of your position.

By following these safety measures, you can significantly reduce risks and ensure your well-being when heavy rain pours down. Stay informed about weather conditions and heed advice from local authorities to make your journey safe and sound.
