Vehicle danger and Turn Around, Don't Drown

The NWS states that most flooding deaths occur in vehicles, as quoted in The State's flash flood warning report.

Never drive through a flooded roadway or around barricades, the NWS states in that warning.

Turn around, don't drown, the NWS states in that warning.

Be aware of your surroundings and do not drive on flooded roads, the NWS states in that warning.

The NWS also warned never to drive through water on the road, even if it appears shallow.

According to the NWS, as little as 12 inches of fast-flowing water can carry away most vehicles.

During periods of intense rainfall, the risk of flooding increases, particularly in low-lying and flood-prone areas, according to guidance in the reports.

It is imperative to avoid driving through any water on the road, even if it seems shallow, according to guidance in the reports.

When coming to a flooded road, turn around and head back, according to guidance in the reports.

Flash flooding currents are strong and can sweep drivers off roadways, according to guidance in the reports.

Driving through deep water can also affect a vehicle's mechanical and electrical systems, according to guidance in the reports.

Household actions for low-lying areas

For either residents or campers of flood-prone, low-lying areas, take immediate action and seek higher ground, according to NWS safety recommendations reproduced in The State reports.

Follow evacuation instructions without delay, according to those NWS recommendations.

If time permits, lock your home upon departure and disconnect utilities and appliances, according to those NWS recommendations.

Avoid entering basements or rooms where electrical outlets or cords are submerged in water, according to those NWS recommendations.

If you see sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate the area immediately, according to those NWS recommendations.

Refrain from entering water that may have electricity in it, according to those NWS recommendations.

Avoid walking through floodwaters, according to those NWS recommendations.

Even 6 inches of moving water can pose a serious risk of knocking you off your feet, according to those NWS recommendations.

If you find yourself trapped by moving water, move to the highest possible point and contact emergency services, according to those NWS recommendations.

Dial 911 if trapped by moving water, according to those NWS recommendations.

Wet-road driving and hydroplaning response

Turn on headlights in rain, according to rainy-weather driving guidance reproduced in The State reports.

Even in daylight, using headlights can help improve visibility and let other drivers know where you are, according to that guidance.

While on the road, opt for the middle lanes and remain on higher ground, according to that guidance.

Rainwater tends to gather along the road edges, according to that guidance.

Steer clear of puddles, according to that guidance.

Driving into puddles or low areas of rainwater can cause vehicles to hydroplane or skid out of control, according to that guidance.

Do not follow large vehicles closely, according to that guidance.

Large vehicles like trucks or buses can create a spray of water that can reduce your visibility, according to that guidance.

Hydroplaning occurs when a vehicle begins to slide uncontrollably on wet roads, according to the NWS background material in the reports.

This happens when water in front of the tire builds up faster than the vehicle's weight can push water out of the way, according to that material.

The water pressure then causes the vehicle to rise and slide on a thin layer of water between the tires and the road, according to that material.

That process makes the driver lose control, according to that material.

Hydroplaning is primarily caused by vehicle speed, according to that material.

When a vehicle's speed increases, the tire-traction grip and ability to control the vehicle decreases, according to that material.

Drive at a reduced speed during wet weather, according to that material.

Hydroplaning is also caused by water depth, according to that material.

The deeper the water, the sooner a vehicle loses traction on the road, according to that material.

Checking your tire tread before hitting the road is important, according to that material.

Low or no tread can lead to sliding, according to that material.

In the event of hydroplaning, ease off the accelerator, according to that material.

Step off the gas to slow down the vehicle until the tires find traction, according to that material.

Turning into the skid can help the vehicle's tires realign to regain control, according to that material.

During the skid, wait until the tires reconnect with the road and then gently straighten the wheels to regain control, according to that material.

Brake normally if the vehicle has anti-lock brakes and pump brakes gently if in an older vehicle, according to that material.
