Update: Anticipate pea-sized hail with thunderstorms in Yosemite Wednesday – gusts could peak at 40 mph

Yosemite, Yosemite Valley, Mariposa Madera Foothills and Mariposa-Madera Lower Sierra were placed under an updated report for strong thunderstorms by the National Weather Service on Wednesday at 4:47 p.m. The alert is in effect until 5:30 p.m.

The storms could bring pea-sized hail (0.25 inches) and wind gusts of up to 40 mph.

“At 4:46 p.m., Doppler radar tracked a strong thunderstorm 7 miles southwest of Yosemite National, or 12 miles northwest of Yosemite South Entrance, moving south at 15 mph,” says 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 El Portal, Badger Pass Ranger Station, Crane Flat Campground, Wawona Campground and Gin Flat.

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.”

Preparing for impending lightning strikes: Expert safety recommendations

Each year, lightning strikes the United States approximately 25 million times, with the majority of these electrifying events occurring during the summer months. Unfortunately, lightning is responsible for claiming the lives of approximately 20 people annually, as reported by 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, 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.
• Stay vigilant by monitoring the sky for ominous signs and listening for the telltale sound of thunder. If thunder is audible, it’s a clear indication of nearby lightning.
• 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.
• 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 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.

Driving through downpours: Safety guidelines for wet roads

Rain can turn roads into hazards. Stay informed and follow these tips from the NWS to ensure safety during heavy rainfall:

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.

Slow down and drive with care:

On wet roads, reducing your speed is crucial. Ease off the gas pedal 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

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:

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 quickly 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.

When stopping by the roadside is your only option, position your vehicle as far off the road as possible, ideally beyond guardrails. Keep your headlights on and activate 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.
