Preparing for approaching lightning: Expert safety advice

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, keep these recommendations in mind:

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’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.

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 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 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 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. 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.

Rainy roadways ahead: Essential safety tips for heavy rain

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

Beware of swollen waterways:

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:

Use the two-second rule to maintain a safe distance from the car in front of you and allow an extra two seconds in heavy rain.

Slow down and drive with care:

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:

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:

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 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.

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.
