Flood warning active for Los Angeles County until Thursday morning due to prolonged rain – Daily News

Los Angeles County was under an updated flood advisory from the National Weather Service on Thursday at 2:51 a.m. The advisory is in effect until 8:15 a.m.
The NWS Los Angeles/Oxnard CA says it is preparing for “flooding from moderate to locally heavy rain that continues. Precipitation rates between 0.25 and 0.45 inches per hour have been observed so far.”
“Minor flooding in low-lying, poorly drained areas. Increasing in normally dry small streams and arroyos. Water accumulations in urban or other areas are occurring or imminent,” according to the NWS. “Turn around, don’t drown when you encounter flooded roads. Most flood deaths occur in vehicles. Be especially careful at night when it is more difficult to recognize flood dangers. Please report observed flooding to local emergency services or law enforcement and ask them to report this information to the National Weather Service when it is safe to do so.”
Deciphering advisories, watches and warnings: understanding weather alerts
- Flash flood alert: act!
A flash flood warning is issued when a flash flood is imminent or in progress. If you are in an area prone to flooding, move to higher ground immediately. A flash flood is a sudden, violent flood that can take anywhere from a few minutes to a few hours to develop. It is even possible to experience flash flooding in areas that do not immediately receive rain.
- Flood alert: act!
A flood warning is issued when flooding is about to occur or is already underway.
- Flood Warning: Caution:
A flood warning is issued when flooding is not expected to be severe enough to issue a warning. However, this may cause significant inconvenience and, if care is not exercised, could lead to situations which may threaten life and/or property.
- Flood Watch: Be Prepared:
A flood watch is issued when conditions are favorable for flooding. This does not mean there will be flooding, but it is possible.
In case of flooding: NWS guidelines for your protection
Flooding can pose a significant threat, especially if you live in a flood-prone area or camp in a low-lying region. To keep you safe, the NWS offers essential flood safety guidelines:
Move to higher ground:
If you are in a flood-prone area or camping in a low-lying area, move to higher ground first.
Follow evacuation orders:
When local authorities issue an evacuation order, obey promptly. Before leaving, secure your accommodation by locking it.
Disconnect utilities and appliances:
If weather permits, unplug your utilities and appliances. This precaution minimizes electrical risks in the event of flooding.
Avoid flooded basements and submerged areas:
Avoid basements or rooms where water has submerged electrical outlets or cords. This helps prevent electrical accidents.
Rapid evacuation for your safety:
If you notice sparks or hear buzzing, crackling, popping or popping sounds, evacuate immediately. Avoid any water that could be charged with electricity.
Avoid walking in flood waters:
Never attempt to cross floodwaters, even if they appear shallow. Just 6 inches of fast-moving water can sweep you away with force.
Seek higher ground if you get stuck:
If you are trapped by moving water, get to the highest point available and contact emergency services by calling 911.
During heavy rain there is a risk of flooding, especially in low-lying and flood-prone areas. It is important to never attempt to cross water on the road, regardless of its depth. According to the NWS, as little as 12 inches of rushing water can wash away most vehicles. Stay safe by being prepared and informed.
Driving in showers: safety instructions on wet roads
When heavy rain sets in, the risk of flooding and dangerous driving conditions increases. Whether it’s prolonged rain or rapid runoff, being prepared is essential. Here are some helpful safety tips from the NWS to keep you safe during heavy rain:
Beware of swollen waterways:
During heavy rain, avoid parking or walking near culverts or drainage ditches, where fast-moving water can pose a serious risk.
Maintain safe driving distances:
Use the two-second rule to maintain a safe distance from the car in front of you and allow two extra seconds in heavy rain.
Slow down and stay safe:
On wet roads, it is essential to slow down. Release the accelerator gradually and avoid sudden braking to avoid skidding.
Choose your path wisely:
Stick to the middle lanes to minimize the risk of hydroplaning. Exterior pathways are more prone to water accumulation.
Prioritize visibility:
Turn on your headlights and watch out for other vehicles behind you and in blind spots, as they are especially difficult to see through rain-spattered windows.
Be careful of slippery roads:
Be very careful during the first half hour after the rain starts. Dirt and oil on the road surface mix with water to make the road slippery.
Keep a safe distance from large vehicles:
Do not follow large trucks or buses too closely. The spray created by their large tires reduces your vision. Also be careful when passing them; if you must succeed, do so with caution.
Pay attention to your windshield wipers:
- Overloaded wiper blades can impair visibility. If rain significantly limits your view, stop and wait for conditions to improve. Seek shelter in rest areas or protected places.
- If the side of the road is your only option, move as far away as possible, preferably beyond the end of a guardrail, and wait for the storm to pass. Keep your headlights on and turn on the hazard lights to alert other drivers of your location.
By following these safety measures, you can significantly reduce the risks and ensure your well-being during heavy rain. Stay informed about weather conditions and heed advice from local authorities to make your trip safe and sound.
