Staying safe as lightning approaches: Expert advice

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 guarantee your safety in the midst of a thunderstorm, take into account the following recommendations:

1. 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.

2. 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.

3. 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 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, 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 weather service 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:

• 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 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:

• 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:

• 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 impairs your vision, pull over and wait for conditions to improve. Seek refuge at rest areas or sheltered 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.

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.
