An updated coastal flood warning was issued by the NWS San Diego CA on Saturday at 2:03 a.m. in effect until Sunday at 3 p.m. for San Diego County Coastal Areas and Orange County Coastal.
“For the Coastal Flood Warning through Sunday afternoon, significant coastal flooding and erosion is likely. For the Beach Hazards Statement from Sunday morning until Sunday evening, surf of 5 to 7 feet with local sets up to 9 feet. For the Coastal Flood Advisory from Sunday afternoon until Tuesday afternoon, minor coastal flooding expected,” can be anticipated according to the NWS. “Greatest impacts on Sunday morning from Tropical Storm Rachel with a combination of increased swell, onshore winds, and high tides locally over 7 feet.”
“Numerous roads and walking paths may be closed due to high water. Low-lying property including homes, businesses, and some critical infrastructure may flood. Shoreline erosion will occur during high tides in the mornings. Elevated surf will lead to a high risk of rip currents,” adds the NWS. “Take the necessary actions to protect flood-prone property. If travel is required, do not drive around barricades or through water of unknown depth. Remain out of the water to avoid hazardous swimming conditions.”
This warning is in effect until Sunday at 3 p.m.
Protect yourself during a flood with these tips from the NWS
For either residents or campers of flood-prone, low-lying areas, take immediate action and seek higher ground. Follow evacuation instructions without delay. If time permits, lock your home upon departure and disconnect utilities and appliances. Avoid entering basements or rooms where electrical outlets or cords are submerged in water. If you see sparks or hear buzzing, crackling, snapping, or popping sounds, evacuate the area immediately. Refrain from entering water that may have electricity in it and avoid walking through floodwaters. Even 6 inches of moving water can pose a serious risk of knocking you off your feet. If you find yourself trapped by moving water, move to the highest possible point and contact emergency services, and dial 911.
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 your headlights – Even when it’s light outside, using headlights can improve visibility and alert other drivers to your presence.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 is the term for when a vehicle begins 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. The top three contributors to hydroplaning are:
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.
