Flash Flood Warning issued February 13 at 5:30PM PST until February 13 at 8:00PM PST by NWS Los Angeles/Oxnard CA


At 530 PM PST, local law enforcement reported dangerous debris flows in Altadena as a result of extremely heavy rainfall that is moving over the area. THIS IS A VERY DANGEROUS SITUATION!

HAZARD...Life threatening debris flows in and around the Eaton
Burn Scar.

SOURCE...Law enforcement reported.

IMPACT...Mud, rock, and debris flows are impacting drainages,
roads, and residences in and directly below the burn
area.

Info on #DebrisFlow cameras. Snipped from FB. #AtmosphericRiver #CAwx

"Update: all seven new cameras are now online
With a major atmospheric river projected to hit Southern California this week, ALERTCalifornia's field team has been working hard to install seven new cameras around Los Angeles to help emergency managers monitor potential debris flows from the Eaton and Palisades burn scars. The Bailey Canyon 1 & 2, Sierra Madre Canyon 1 & 2, and Sierra Madre Bridge cameras are already online for the the Eaton Fire scar. Cloudcroft 1 & 2 cameras will be online soon for the Palisades Fire scar. Search camera names at cameras.alertcalifornia.org to see their locations."

@exador23 @ai6yr One thing that was learned from the 2018 Montecito #DebrisFlow was that at bends in the channel the material sometimes tends to pile up and then overshoot the bank on the downward side. The debris flow then continues *outside* the channel by finding a new path of least resistance which could very well be right down streets, through yards, etc.

When this map opens it is centered on the #EatonFire area and shows the drainage ways with a black dot at the low end of each one. The map also shows the weather radar with yellow areas indicating heavier rain than green areas.

There is concern that heavy rains may cause #DebrisFlow

You can drag the map over to the area of the #PalisadesFire and see the same thing.

The colors on this map always show an estimate from NOAA of the rainfall expected over the next 5 days. As is typical, south facing slopes are expected to receive increased rain.

The map also shows pink shading for recent fire perimeters including for the #EatonFire and #PalisadesFire where there is at least some #DebrisFlow risk.

Butte County:

What about Flood Insurance?
Butter County California

"Due to the recent fires, many areas of Butte County will be more susceptible to flooding and debris flows as we move into the rainy season. Did you know that homeowners insurance does not typically cover damage caused by flooding and debris flows? Flood insurance is available, but it’s important to know that it takes 30 days after payment of premium for a flood insurance policy to go into effect. If you are considering purchasing a flood insurance policy, don’t wait for rain to be in the forecast! "
