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 weather service. 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 vital to establish a clear plan for seeking shelter in case of lightning.
• 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, which 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 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. 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.

Navigating rainy roads: Safety tips for wet weather

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

Beware of rapid water flow:

Avoid parking or walking in close proximity to culverts or drainage ditches, as the swiftly moving water during heavy rain can potentially carry you away.

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:

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:

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

Prioritize visibility

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:

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:

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:

Heavy rain can overload the wiper blades. When visibility is so limited that the edges of the road or other vehicles cannot be seen at a safe distance, it is time to pull over and wait for the rain to ease up. It is best to stop at rest areas or other protected areas.

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.

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.
