Yosemite and Upper San Joaquin River are included in a report for strong thunderstorms by the National Weather Service on Saturday at 6:55 a.m. The alert is in effect until 7:30 a.m.
The storms are predicted to bring pea-sized hail (0.25 inches) and wind gusts of up to 40 mph.
“At 6:54 a.m., Doppler radar tracked a strong thunderstorm 13 miles southwest of June Lake, moving north at 15 mph,” states the NWS Hanford CA. “Gusty winds could knock down tree limbs and blow around unsecured objects. Minor hail damage to vegetation is possible.”
Locations impacted by the alert include Vogelsang High Sierra Camp, Tuolumne High Sierra Camp, Tuolumne Meadows, Tuolumne Meadows Visitor Center, Tuolumne Meadows Campground and Merced Lake Ranger Station.
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.”
Shielding yourself from approaching lightning: Expert safety guidelines
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 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 away.
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.
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.
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 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 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, 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.
Navigating rainy roads: Safety tips for wet weather
When heavy rain pours, the risk of flooding and treacherous roads rises. Here’s your guide from the NWS to staying safe during downpours:
Beware of swollen waterways:
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:
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.
Prioritize visibility
Enhance your visibility in heavy rain by turning on your headlights. Watch out for vehicles in blind spots, as rain-smeared windows can obscure them.
Watch out for slippery roads:
The first half-hour of rain is when roads are slickest due to a mix 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:
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.
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.
