Yosemite, San Joaquin River Canyon and Upper San Joaquin River are included in a weather alert for strong thunderstorms by the National Weather Service on Friday at 2:01 p.m. The alert is in effect until 2:30 p.m.
The storms are foreseen to bring pea-sized hail (0.25 inches).
“At 2:01 p.m., Doppler radar tracked a strong thunderstorm 15 miles east of Yosemite South Entrance, moving south at 5 mph,” according to the NWS Hanford CA. “Minor hail damage to vegetation is possible.”
Locations impacted by the alert include Nature Point, Clover Meadow Wilderness Office, Minarets and Graveyard Meadow.
According to the NWS, “If outdoors, consider seeking shelter inside a building. 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
Each year, lightning strikes the United States approximately 25 million times, mostly during the summer. It claims the lives of about 20 people annually, according to the NWS. 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 ensure your safety during a thunderstorm, consider the following recommendations:
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 shelter promptly in a safe location, 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 without access to indoor shelter during a thunderstorm, take these steps to maximize your safety:
Avoid open fields, hilltops, or ridge crests, which 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 in a group, ensure that individuals are spaced 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. Although water and metal do not 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.
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 rapid water flow:
Avoid parking or walking in close proximity to culverts or drainage ditches, as the swiftly moving water during heavy rain can potentially carry you away.
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 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:
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:
Be extra careful during the first half hour after rain begins. Grime and oil on the road surface mix with water to make the road slippery.
Keep a safe distance from large vehicles:
Don’t follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Take care when passing them as well; if you must pass, do so with caution.
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.
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.
