An updated weather alert was issued by the NWS Spokane WA on Sunday at 5 p.m. for strong thunderstorms until 5:30 p.m. for Washington Palouse and Upper Columbia Basin.

Wind gusts of up to 30 mph and marble-sized hail (0.5 inches) are likely.

"At 4:59 p.m., Doppler radar tracked a strong thunderstorm 21 miles east of Ritzville, or 32 miles southwest of Cheney, moving southwest at 10 mph," according to the NWS. "Gusty winds could knock down tree limbs and blow around unsecured objects. Minor hail damage to outdoor objects is possible."

The alert is for Revere.

The NWS comments, "If outdoors, consider seeking shelter inside a building. Heavy rainfall is also occurring with this storm and may lead to localized flooding of poor drainage areas. Do not drive your vehicle through flooded roadways."

This alert is in effect until 5:30 p.m.

Actions to take when lightning threat is imminent

Around 25 million lightning strikes occur in the United States every year, with most taking place during the summer months. The NWS reports that these strikes result in about 20 fatalities annually. The probability of lightning strikes rises as a thunderstorm approaches and peaks when the storm is directly above. As the storm moves away, this likelihood decreases.

Here are tips on how to stay safe 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 becomes menacing and thunder becomes audible, seek out a safe place to seek shelter.
• Once inside, abstain from touching corded phones, electrical devices, 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.
• Stay away from tall, isolated trees or other tall objects. If you are in a forest, stay near a lower stand of trees.
• If you are with a group, fan out to stop the current from transmitting between 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.
• Do not approach water, wet objects, or metal items. Although water and metal do not attract lightning, they conduct electricity effectively.

What to do in the rain on the road?

• 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.
• Steer clear of flooded areas - When coming to a flooded road, turn around and head back. Flash flooding currents are strong and can sweep drivers off roadways. Driving through deep water can also affect a vehicle's mechanical and electrical systems.

What is hydroplaning?

Hydroplaning is the term for when a vehicle begins 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. The three main causes of hydroplaning are:

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.
