UPDATE: North Texas under a flood watch until Sunday evening, says the NWS

On Sunday at 7:15 a.m. the NWS Fort Worth TX issued an updated flood watch. The watch is for Fannin, Lamar, Collin, Hunt, Delta, Hopkins, Tarrant, Dallas, Rockwall, Kaufman, Van Zandt, Rains, Johnson, Ellis, Henderson, Bosque, Hill, Navarro, Freestone, Anderson, McLennan, Falls, Limestone, Leon, Milam and Robertson counties.

Flooding caused by excessive rainfall continues to be possible for portions of north central, northeast, and south central Texas, including in north central Texas, Bosque, Collin, Dallas, Ellis, Falls, Fannin, Freestone, Hill, Hunt, Johnson, Kaufman, Limestone, McLennan, Navarro, Rockwall and Tarrant counties. In northeast Texas, Anderson, Delta, Henderson, Hopkins, Lamar, Leon, Rains and Van Zandt. In south central Texas, Milam and Robertson until 7 p.m. this evening.

"Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations," describes the NWS. "You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop."

This watch is in effect until 7 p.m.

Ways to stay safe during a flood according to the NWS

If you reside in a flood-prone area or you are camping in a low-lying area, move to higher ground. If told to evacuate, do so immediately. Lock your home before departing. If time allows, disconnect utilities and appliances. Avoid basements or rooms where water has submerged electrical outlets or cords. If you notice sparks or hear buzzing, crackling, snapping, or popping noises, evacuate immediately. Avoid any water that may be charged with electricity and do not attempt to walk through floodwaters. Even 6 inches of swiftly moving water can forcefully knock you off your feet. If you become trapped by moving water, seek the highest possible point and contact emergency services by calling 911.

During heavy rainfall, there is a risk of flooding, especially in low-lying and flood-prone areas. Remember to never drive through water on the road, even if it seems shallow. According to the NWS, as little as 12 inches of rapidly flowing water can carry away most cars.

Rainy weather driving tips

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

• While driving — Stick to the middle lanes and stay on elevated ground. Rainwater tends to accumulate at 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. 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.
