An updated flood warning was issued by the National Weather Service on Thursday at 2:37 p.m. in effect until Friday at 5:46 a.m.

Minor flooding is occurring for East Fork Trinity River at McKinney until late tonight.

"At 16.0 feet, Minor out of bank flooding will begin along the river," describes the NWS. "Do not drive cars through flooded areas. Caution is urged when walking near riverbanks."

This warning is in effect until Friday at 5:46 a.m.

Recommendations from the NWS for staying safe during a flood

In case you reside within a flood-prone area or are currently camping in a low-lying zone, it is crucial to promptly seek higher ground. If told to evacuate, do so immediately. Ensure your home is securely locked when vacating the premises. If time permits, disconnect utilities and appliances. Avoid entering basements or rooms with submerged electrical outlets or cords. Should you observe sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate immediately. Refrain from entering water that might carry an electric current and avoid walking through floodwaters. Remember, as little as 6 inches of moving water can knock you off your feet. If trapped by moving water, seek the highest possible point and contact emergency services by calling 911.

When heavy rain occurs, there is a risk of flooding, particularly in low-lying and flood-prone regions. It is important to never attempt to drive through water on the road, regardless of how deep it appears. According to the NWS, as little as 12 inches of rushing water can sweep away most vehicles.

What steps to follow when driving in the rain?

• 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.

• Avoid puddles — Driving into puddles or low rainwater areas can lead to vehicles hydroplaning or losing 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 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. The three main causes of 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.
