UPDATE: Flash flood warning affecting Ellis and Johnson counties Tuesday midday, according to the NWS

The National Weather Service issued an updated flash flood warning at 11:16 a.m. on Tuesday in effect until noon.

"At 11:16 a.m., Doppler radar and automated rain gauges indicated thunderstorms producing heavy rain across the warned area. Between 1 and 2.5 inches of rain have fallen. Flash flooding is ongoing or expected to begin shortly," states the NWS. "Flooding of small creeks and streams, urban areas, highways, streets, and underpasses as well as other poor drainage and low-lying areas."

Locations impacted by the warning include Fort Worth, Grand Prairie, Mansfield, Cedar Hill, Burleson, Lancaster, Waxahachie, Cleburne, Ennis, Midlothian, Crowley, Glenn Heights, Red Oak, Keene, Joshua, Alvarado, Rendon, Ovilla, Venus and Ferris.

According to the NWS, "Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be aware of your surroundings and do not drive on flooded roads."

This warning is in effect until noon.

Ways to stay safe during a flood according to the NWS

For either residents or campers of flood-prone, low-lying areas, take immediate action and seek higher ground. Follow evacuation instructions without delay. If time permits, lock your home upon departure and disconnect 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, snapping, or popping sounds, evacuate the area immediately. Refrain from entering water that may have electricity in it and avoid walking through floodwaters. Even 6 inches of moving water can pose a serious risk of knocking you off your feet. If you find yourself trapped by moving water, move to the highest possible point and contact emergency services, and dial 911.

During heavy rain, flooding is possible, especially in low-lying and flood-prone areas. Never drive through water on the road, even if it does not appear to be deep. It takes just 12 inches of rushing water to carry away most cars, according to the NWS.

What steps to follow when driving in the rain?

• Switch on headlights — Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.

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

• Steer clear of puddles — Driving into puddles or low areas of rainwater can cause vehicles to hydroplane or skid out of control.

• Maintain a safe distance from large vehicles — Trucks or buses can produce a water spray that hampers 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 is when a vehicle starts uncontrollably sliding 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 top three contributors to 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.
