At 1:39 a.m. on Friday, the National Weather Service issued an updated flood warning in effect until 3:43 p.m. for Johnson and Jackson counties.

The NWS informs, “Minor flooding is occurring and minor flooding is forecast for Indian Creek at Stateline Road Leawood.”

“At 20.0 feet, Water begins to cover the portion of Lee Boulevard located south of Interstate 435. At 23.0 feet, Parking lot just west of State Line Road begins to flood,” states the NWS. “Turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.”

This warning is in effect until 3:43 p.m.

Ways to stay safe during a flood according to 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.

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 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.
• 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 happens when a vehicle starts 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 most commonly attributed to 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.
