Prepare for sudden gusty winds. Secure loose objects and move to a safe shelter inside a building or vehicle.”

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, consider the following recommendations:

Lightning safety plan:

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

• 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’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 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 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. 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, 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 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:

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.

Slow down and drive with care:

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.

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:

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:

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.

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.
