Collin and Grayson counties under a flood advisory until Thursday night, says the NWS
The NWS Fort Worth TX issued a flood advisory at 8:06 p.m. on Thursday.
Urban and small stream flooding caused by excessive rainfall is expected for Collin and Grayson counties until 11:15 p.m.
"Minor flooding in low-lying and poor drainage areas. Water over roadways," explains the NWS. "Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be especially cautious at night when it is harder to recognize the dangers of flooding."
This advisory is in effect until 11:15 p.m.
Protect yourself during a flood with these tips from the NWS
If you live in a flood-prone area or are camping in a low-lying area, get to higher ground immediately. If told to evacuate, do so immediately. Lock your home when you leave. If you have time, disconnect utilities and appliances. Don’t go into a basement, or any room, if water covers the electrical outlets or if cords are submerged. If you see sparks or hear buzzing, crackling, snapping, or popping noises, get out. Stay out of water that may have electricity in it. Don’t walk through flood waters. It only takes 6 inches of moving water to knock you off your feet. If you are trapped by moving water, move to the highest possible point and call 911 if possible.
During periods of intense rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas. It is imperative to avoid driving through any water on the road, even if it seems shallow. According to the NWS, most cars can be swept away by just 12 inches of rushing water.
What steps to follow when driving in the rain?
• Turn on headlights — Even in daylight, using headlights can help improve visibility and let other drivers know where you are.
• On the road — Drive in the middle lanes and stay on high ground. Rainwater tends to stockpile on the edges of roads.
• 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 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.
