Preparing for approaching lightning: Expert safety 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 weather service. 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 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.
• 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 a safe place to shelter, 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.
• 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, 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 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.

Mastering wet roads: Safety tips for heavy rainfall

Heavy rainfall may lead to flooding if prolonged or if there is excessive runoff. Excessive runoff can be a result of saturated ground and/or rainfall intensity. Follow these recommendations from the weather service to stay safe in heavy rain:

Beware of rapid water flow:

• In heavy rain, refrain from parking or walking near culverts or drainage ditches, where swift-moving water can pose a grave danger.

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

• 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:

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

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.
