Staying safe as lightning approaches: Expert advice

Lightning strikes the United States approximately 25 million times each year, with the bulk of these electrical discharges occurring during the summer months. Tragically, lightning claims the lives of about 20 individuals annually, as reported by the NWS. The risk of lightning-related incidents escalates as thunderstorms draw near, reaching its peak when the storm directly looms overhead. However, it gradually recedes as the tempest moves away.

To protect yourself during a thunderstorm, take these recommendations into consideration:

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’re indoors, avoid using corded phones, electrical devices, plumbing fixtures, and stay away from 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 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 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 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.

Mastering wet roads: Safety tips for heavy rainfall

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:

During heavy rain, avoid parking or walking near culverts or drainage ditches, where swift-moving water can pose a serious risk.

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 stay cautious:

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:

Stick to the middle lanes on multi-lane roads to minimize the risk of hydroplaning, as water tends to accumulate in outer lanes.

Prioritize visibility

Enhance your visibility in heavy rain by activating your headlights. Be particularly vigilant for vehicles in blind spots, as rain-smeared windows can obscure them.

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:

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

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.

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.
