Yosemite, San Joaquin River Canyon and Upper San Joaquin River are under 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 could 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," the NWS Hanford CA said. "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."
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.

If you find yourself outdoors without access to indoor shelter during a thunderstorm, take these steps to maximize your safety:
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.
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 rapid water flow:
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:
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.
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 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 impairs your vision, pull over and wait for conditions to improve. Seek refuge at rest areas or sheltered 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.
