An updated report was issued from the NWS Portland OR on Friday at 7:46 p.m. for strong thunderstorms until 8:15 p.m. The alert is for Cowlitz County Lowlands, North Clark County Lowlands and Inner Vancouver Metro.

The storms are packing pea-sized hail (0.25 inches).

"At 7:46 p.m., Doppler radar tracked a strong thunderstorm near Scappoose, or 9 miles west of Vancouver Downtown, moving north at 15 mph," says the NWS. "Minor hail damage to vegetation is possible."

Locations impacted by the alert include St. Helens, Vancouver, Scappoose, Ridgefield, Warren, Sauvie Island and Spitzenberg. In Oregon this includes U.S. Highway 30 west of Portland between mile markers 10 and 29.

The NWS comments, "If outdoors, consider seeking shelter inside a building."

This alert is in effect until 8:15 p.m.

What to do as threat of lightning approaches?

Lightning hits the United States approximately 25 million times annually. The majority of these strikes happen during the summer, causing around 20 fatalities each year, according to the NWS. The likelihood of lightning increases as a thunderstorm gets closer and reaches its highest point when the storm is directly overhead. This risk decreases as the storm moves away.

Here are recommendations for maintaining safety during a thunderstorm:

• To lower the risk of lightning strikes, when going outdoors, develop a plan to reach a safer spot.
• If the sky becomes menacing and thunder becomes audible, seek out a safe place to seek shelter.
• Once indoors, avoid touching corded phones, electrical equipment, plumbing, and windows and doors.
• Wait for 30 minutes after the last lightning or thunder before going back out.

If finding indoor shelter is not an option:

• Avoid open fields, hill peaks, 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.
• When in a group, space out to prevent the current from transferring between individuals.
• If you are camping in an open space, choose a valley, ravine, or low area for your campsite. Remember, tents do not shield you from lightning.
• Maintain a safe distance from water, wet items, and metal objects. Water and metal do not attract lightning, yet they conduct electricity efficiently.

Rainy weather driving tips

• Switch on headlights - Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.
• On the road - Drive in the middle lanes and stay on high ground. Rainwater tends to stockpile on the edges of roads.
• Keep clear of puddles - Driving through puddles or low rainwater areas can cause vehicles to hydroplane or skid out of 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.
