Where to get sandbags

If you’re in an area at risk of flooding, sandbags can be one line of defense. County fire departments typically offer a limited supply of free sandbags for residents of their nearby communities. You should bring your own shovel to fill your bags, and be prepared to show proof of residency.

Sand and sandbags can also be purchased at many home improvement and hardware stores.

When lightning looms: Expert safety tips for thunderstorms

Lightning strikes the United States approximately 25 million times each year, mostly during the summer. Lightning claims the lives of about 20 people annually, according to 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

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

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.

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 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 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, 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.

Navigating heavy rain: Essential safety measures for wet roads

When heavy rain strikes, safety is paramount. Equip yourself with these guidelines from the NWS to navigate wet roads and avoid hazards:

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:

Adhere to the two-second rule for maintaining a safe following distance behind the vehicle in front of you. In heavy rain, allow an additional two seconds of distance to compensate for reduced traction and braking effectiveness.

Reduce speed and drive cautiously:

If it is raining and the roads are wet, slow down. Take your foot off the accelerator and let your speed drop gradually. Never use the brakes suddenly because this may cause the car to skid.

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.

Visibility matters:

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 with caution.

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.
