How to protect yourself from lightning strikes: Safety tips from experts

Lightning strikes occur about 25 million times each year in the United States, with the majority of these electrical discharges occurring during the summer months. Tragically, lightning strikes claim the lives of about 20 people each year, according to the Weather Service. The risk of lightning strikes increases as thunderstorms approach, peaking when the storm is directly overhead. However, it gradually subsides as the storm recedes.

To ensure your safety during a thunderstorm, follow these recommendations:

Lightning protection plan:

• If you are outdoors, it is important to have a lightning protection plan.
• Watch the sky for ominous signs and listen for sounds of thunder. If thunder is heard, it is an indication that lightning is nearby.
• Immediately seek shelter in a safe place, preferably indoors.

Indoor safety measures:

• Avoid using corded telephones, electrical appliances or plumbing indoors and stay away from windows and doors.
• These precautions help reduce the risk of electrical surges, as lightning can follow conductive paths.

Wait for the all-clear:

• Wait at least 30 minutes after the last lightning strike or clap of thunder before resuming outdoor activities.
• Even when a thunderstorm appears to be over, lightning can still strike, so be careful.

If no shelter is available in the house:

If you are outdoors during a thunderstorm and do not have access to shelter, take the following steps to maximize your safety:

• Avoid open fields, hilltops or ridges where the risk of lightning strikes is greater.
• Stay away from tall, isolated trees and other prominent objects. In forested areas, stay close to lower stands of trees.
• If you are traveling in a group, make sure that everyone is spread out to prevent lightning current from being transmitted between people.
• Camping outdoors during a thunderstorm is strongly discouraged. If there is no alternative, set up camp in a valley, ravine or other low area. Remember that a tent does not provide protection from lightning strikes.
• Do not approach bodies of water, wet objects, or metal objects. Although water and metal do not attract lightning, they are good conductors of electricity and can pose significant risks.

In summary, vigilance and preparation are your best allies when you are at risk of being struck by lightning. By following these guidelines, you can significantly reduce the likelihood of lightning accidents and put your safety first.

Driving in heavy rain: safety tips for wet roads

Heavy rains can cause flooding if they last for a long time or if there is excessive runoff. Excessive runoff can be due to saturated soil and/or rainfall intensity. Follow these weather service recommendations to stay safe during heavy rain:

Be careful with fast water flow:

Avoid parking or walking in close proximity to culverts or drainage ditches, as fast-flowing water may sweep you away during heavy rain.

Keep the safety distance:

In heavy rain, the two-second following rule is helpful. Increase it to four seconds to ensure a safe following distance in adverse conditions.

Slow down and be careful:

On wet roads, it is extremely important to slow down. Ease off the accelerator and avoid sudden braking to prevent skidding.

Choose your lane carefully:

Stay in the middle lanes as water often collects in the outside lanes.

Prioritize visibility

Improve your visibility in heavy rain by turning on your headlights. Pay particular attention to vehicles in your blind spot, as rain-smeared windows can obscure them.

Be careful of slippery roads:

Be especially careful in the first half hour after the rain starts. Dirt and oil on the road surface mix with water and make the road slippery.

Keep a safe distance from large vehicles:

Do not drive too close behind large trucks or buses. The spray created by their large tires will limit your visibility. Also be careful when overtaking; if you must overtake, do so quickly and safely.

Pay attention to your windshield wipers:

Overloaded wiper blades can reduce visibility. If rain is severely affecting your visibility, pull over to the side of the road and wait for conditions to improve. Seek shelter in rest areas or places sheltered from the wind.

If the side of the road is your only option, pull over as far as possible, preferably to the end of a guardrail, and wait for the storm to pass. Keep your headlights on and turn on your hazard lights to alert other drivers to your position.

In heavy rain, these precautions can go a long way to keeping you safe on the road. Remember to check weather conditions and follow the instructions of local authorities to ensure a safe journey.
