Flash flood warning issued for Collin and Denton counties through early Sunday morning, according to the NWS

A flash flood warning was issued by the NWS Fort Worth TX Sunday at 2:22 a.m.

“At 2:22 a.m., Doppler radar indicated thunderstorms producing heavy rain in the alerted area. Between 1 and 2.5 inches of rain fell. Flash flooding is in progress or expected to begin shortly,” the NWS says. “Flooding of small streams and creeks, urban areas, highways, streets and underpasses as well as other poor drainage and low lying areas.”

Locations affected by the warning include Dallas, Fort Worth, Plano, Garland, McKinney, Carrollton, Frisco, Denton, Richardson, Lewisville, Allen, Flower Mound, Grapevine, Wylie, Coppell, The Colony, Southlake, Sachse, Corinth and Highland Village.

The NWS adds: “Turn around, don’t drown when you encounter flooded roads. Most flood deaths occur in vehicles. Be especially careful at night when it is more difficult to recognize flood dangers.

This warning is in effect until 5:30 a.m.

Protect yourself during a flood with these tips from the NWS

Whether residents or campers in low-lying areas prone to flooding, act immediately and seek higher ground. Follow evacuation instructions immediately. If weather permits, lock your home upon departure and unplug utilities and appliances. Avoid entering basements or rooms where electrical outlets or cords are submerged in water. If you see sparks or hear buzzing, crackling, popping, or popping sounds, evacuate the area immediately. Avoid entering water that may contain electricity and avoid walking through flood water. Even 6 inches of moving water can pose a serious risk of causing you to fall. If you find yourself trapped by moving water, move to the highest point possible, contact emergency services and call 911.

During periods of intense rainfall, the risk of flooding increases, particularly in low-lying, flood-prone areas. It is imperative to avoid driving through water on the road, even if it appears shallow. According to the NWS, most cars can be swept away by as little as 12 inches of rushing water.

What steps should you take when driving in the rain?

• Turn on the headlights — Even in broad daylight, using your headlights can help improve visibility and let other drivers know where you are.

• On the road — Take the middle lanes and stay high. Rainwater tends to accumulate along roadsides.

• Avoid puddles — Driving through puddles or low areas of rainwater can cause vehicles to hydroplane or skid out of control.

• Do not follow large vehicles closely – Large vehicles like trucks or buses can create a spray of water that can reduce your visibility.

• Avoid flooded areas — When you come to a flooded road, turn around and go back. Flash flood currents are strong and can sweep drivers off the roads. Driving in deep water can also 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 accumulates faster than the weight of the vehicle can push the water away. The water pressure then causes the vehicle to rise and slide on a thin layer of water between the tires and the road, causing the driver to lose control. The three main factors contributing to hydroplaning are:

1. Vehicle Speed ​​— As a vehicle’s speed increases, tire grip and the ability to control the vehicle decreases. Drive at reduced speed in rainy weather.

2. Water Depth — The deeper the water, the sooner a vehicle loses traction on the road. No matter how deep the water is, even a thin layer can cause hydroplaning.

3. Tire Tread Depth — It’s important to check the tread on your tires before hitting the road, as weak or no tread can lead to slipping.

If your vehicle hydroplanes, here is what you need to know:

• Release the accelerator — Release the accelerator to slow the vehicle until the tires find traction.

• Steering on the skid — Steering on the skid can help the vehicle’s tires realign and regain control.

• Make sure the tires reconnect with the road — While skidding, wait for the tires to reconnect with the road, then gently straighten the wheels to regain control.

• Brake gently if necessary — Brake normally if the vehicle has anti-lock brakes and pump the brakes gently if it is an older vehicle.
