Thunderstorms with nickel-sized hail in North Texas Wednesday

A report from the NWS Fort Worth TX on Wednesday at 12:05 p.m. warns of strong thunderstorms until 12:30 p.m. The alert is for Collin, Dallas, Rockwall, Kaufman and Ellis counties.

The storms could bring nickel-sized hail (0.88 inches).

"At 12:04 p.m., Doppler radar tracked strong thunderstorms along a line extending from near Lucas to Ferris. Movement was north at 15 mph," according to the NWS. "Minor damage to outdoor objects is possible."

Expect strong thunderstorms in the following locations:

• Dallas, Garland, Mesquite, Richardson, Rowlett, Wylie, Lancaster, Balch Springs, Sachse, and Seagoville around 12:10 p.m.

• Princeton around 12:15 p.m.

The NWS adds, "If outdoors, consider seeking shelter inside a building. If on or near Lake Lavon and Lake Ray Hubbard, get out of the water and move indoors or inside a vehicle. Remember, lightning can strike out to 10 miles from the parent thunderstorm. If you can hear thunder, you are close enough to be struck by lightning. Move to safe shelter now! Do not be caught on the water in a thunderstorm."

This alert is in effect until 12:30 p.m.

How to react when facing a lightning hazard?

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 lower the risk of lightning strikes, when going outdoors, develop a plan to reach a safer spot.

• If the sky becomes threatening and thunder can be heard, find a safe place to shelter.

• Once inside, abstain from touching corded phones, electrical devices, plumbing, and windows and doors.

• Wait 30 minutes after the last lightning or thunder before going back 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 in a group, spread out to avoid the current traveling between group members.

• If you are camping in an open setting, set up camp in a valley, ravine, or other low spot. Bear in mind, a tent does not protect 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.

What to do in the rain on the road?

• Turn on your headlights — Even when it's light outside, using headlights can improve visibility and alert other drivers to your presence.

• 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

• Don't tail large vehicles closely — Trucks or buses can kick up a water spray that obstructs visibility.

• Avoid flooded areas — When encountering a flooded road, do a U-turn and head back. The strong currents from flash floods can pull drivers off roadways. Driving through deep water can also negatively affect a vehicle's mechanical and electrical systems.

What is hydroplaning?

Hydroplaning occurs when a vehicle begins to slide 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 primarily caused by 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.
