A report from the NWS Sacramento CA was issued on Thursday at 7:01 p.m. for strong thunderstorms until 7:30 p.m. for Sierra Nevada of El Dorado and Amador counties Between 3000-5000 ft Including Highway 50 and Sierra Nevada of El Dorado-Amador-Northern Alpine counties Above 5000 ft Including Highway 50.

Wind gusts of up to 30 mph and pea-sized hail (0.25 inches) are anticipated.

"At 6:59 p.m., Doppler radar tracked a strong thunderstorm over Kyburz, or 13 miles west of Kirkwood, moving north at 5 mph," describes the NWS. "Gusty winds could knock down tree limbs and blow around unsecured objects. Minor hail damage to vegetation is possible."

The alert is for Kyburz.

The NWS states, "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 alert is in effect until 7:30 p.m.

What to do as threat of lightning approaches?

Lightning strikes the United States about 25 million times a year. Most of the strikes occur in the summer, killing 20 people each year, according to the NWS. Chance of lightning increases as a thunderstorm approaches and peaks when the storm is overhead. It diminishes as the storm moves away.

Here are recommendations for maintaining safety during a thunderstorm:

• To decrease the risk of getting struck by lightning, when you go outside, establish a plan to reach a safer place.
• If the sky grows ominous and you hear thunder, seek out a safe place to take shelter.
• Once indoors, avoid touching corded phones, electrical equipment, plumbing, and windows and doors.
• Wait for 30 minutes after the most recent lightning or thunder before venturing outside.

If finding indoor shelter is not an option:

• Stay away from open fields, hill summits, or ridge tops.
• Keep a distance from tall, solitary trees or other elevated structures. When in a forest, stay in proximity to shorter tree groupings.
• If you are in a group, disperse to prevent the current from passing between group members.
• When camping in an open environment, select a campsite in a valley, ravine, or low region. Just remember, tents do not offer protection from lightning.
• Stay away from water, wet items, and metal objects. Water and metal do not attract lightning but they are excellent conductors of electricity.

What steps to follow when driving in the rain?

• Switch on headlights - Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.
• While on the road - Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along the road edges.
• Avoid puddles - Driving into puddles or low rainwater areas can lead to vehicles hydroplaning or losing control.
• Give ample space to large vehicles - Trucks or buses can create a water spray that diminishes visibility.
• Avoid flooded zones - If you encounter a flooded road, make a U-turn and go back. The powerful currents of flash floods can carry drivers off the road. Driving through deep water can also damage a vehicle's mechanical and electrical systems.

What is hydroplaning?

Hydroplaning happens when a vehicle starts sliding uncontrollably on wet roads.

This happens when water in front of the tire builds up faster than the vehicle's weight can push water out of the way. The water pressure then causes the vehicle to rise and slide on a thin layer of water between the tires and the road, making the driver lose control. Hydroplaning is most commonly attributed to three factors:

1. Vehicle speed - When a vehicle's speed increases, the tire-traction grip and ability to control the vehicle decreases. Drive at a reduced speed during wet weather.
2. Water depth - The deeper the water, the sooner a vehicle loses traction on the road. It doesn't matter how deep the water is, even a thin layer can lead to hydroplaning.
3. Tire tread depth - Checking your tire tread before hitting the road is important, as low or no tread can lead to sliding.

In the event of your vehicle hydroplaning, here's what to know:

• Ease off the accelerator - Step off the gas to slow down the vehicle until the tires find traction.
• Turn into the skid - Turning into the skid can help the vehicle's tires realign to regain control.
• Make sure the tires reconnect with the road - During the skid, wait until the tires reconnect with the road and then gently straighten the wheels to regain control.
• Brake gently as needed - Brake normally if the vehicle has anti-lock brakes and pump brakes gently if in an older vehicle.
