On Wednesday at 3:50 p.m. an updated flash flood warning was released by the NWS Greenville-Spartanburg SC in effect until 9:30 p.m. for Caldwell County.
"At 3:50 p.m., Doppler radar indicated thunderstorms producing heavy rain across the warned area. Between 3 and 5 inches of rain have fallen. Additional rainfall amounts of 1-2 inches are possible in the warned area. Significant flash flooding is ongoing or expected to begin shortly. Please seek higher ground NOW and avoid all streams and drainages in the Buffalo Creek watershed," states the NWS. "Life threatening flash flooding of creeks and streams, urban areas, highways, streets and underpasses. Significant inundation of roads is possible. Some structures may be flooded."
The warning is for Buffalo Creek valley, associated tributaries in the Buffalo Cove Community. Areas of concern include near Buffalo Cove Road and Stone Mountain Road and Cove Branch Road.
According to the NWS, "Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain. Do not attempt to cross flooded roads. Find an alternate route. Flooding is occurring or is imminent. It is important to know where you are relative to streams, rivers, or creeks which can become killers in heavy rains. Campers and hikers should avoid streams or creeks. Heavy rain is increasing the risk of landslides, especially in areas where slides have occurred in the past. Be especially alert if you are near a stream, especially at the base of a mountain or in a cove. Watch for loose-moving soil and rocks or a sudden increase in streamflow. Leave the area quickly if this is observed. When driving along roads where the terrain is steep or rocky, watch and listen for falling rocks, mud, trees, and other debris."
This warning is in effect until 9:30 p.m.
Recommendations from the NWS for staying safe during a flood
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 to do in the rain on the road?
- Switch on headlights - Even during daylight hours, using headlights can enhance visibility and signal your presence to other drivers.
- While on the road - Opt for the middle lanes and remain on higher ground. Rainwater tends to gather along the road edges.
- Keep clear of puddles - Driving through puddles or low rainwater areas can cause vehicles to hydroplane or skid out of control
- Do not follow large vehicles closely - Large vehicles like trucks or buses can create a spray of water that can reduce your 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 most commonly attributed to three factors:
- 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.
- 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.
- 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.
