The National Weather Service issued a weather alert at 4:21 p.m. on Monday for strong thunderstorms in effect until 4:45 p.m. for Yosemite.
The storms may bring pea-sized hail (0.25 inches).
“At 4:21 p.m., Doppler radar tracked a strong thunderstorm 13 miles north of Yosemite Valley, or 20 miles southwest of Twin Lakes, moving northeast at 20 mph,” says the NWS Hanford CA. “Minor hail damage to vegetation is possible.”
The NWS said, “If outdoors, consider seeking shelter inside a building. Torrential rainfall is also occurring with this storm and may lead to localized flooding. Do not drive your vehicle through flooded roadways. Frequent cloud to ground lightning is occurring with this storm. Lightning can strike 10 miles away from a thunderstorm. Seek a safe shelter inside a building or vehicle. This storm may intensify, so be certain to monitor local radio stations and available television stations for additional information and possible warnings from the National Weather Service.”
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 ensure your safety during a thunderstorm, keep these recommendations in mind:
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’ve found shelter indoors, abstain from using corded phones, electrical appliances, or plumbing fixtures, and refrain from approaching 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 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 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.
Rainy roadways ahead: Essential safety tips for heavy rain
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:
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:
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 drive with care:
On wet roads, reducing your speed is crucial. Ease off the accelerator gradually and avoid abrupt braking to prevent skidding.
Choose your lane wisely:
Stick to the middle lanes to minimize the risk of hydroplaning. Outer lanes are more prone to accumulating water.
Visibility matters:
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 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.
