"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."

PARTS OF MALIBU, TOPANGA AND ALL OF SUNSET MESA are under EVACUATION WARNING until at least 2/14/25 2pm due to risk to of losing access. PREPARE NOW.

@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.
#AtmosphericRiver #CAwx
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.

From Los Angeles Times: Powerful new rainstorm brings risk of debris flows to L.A. fire zones this week
#DebrisFlow possible for #EatonFire and #PalisadesFire
Open interactive map with lots of links for more information. It will automatically zoom in on the Eaton fire. You can pan the map to the Palisades fire.

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! "
NOAA has issued a #FlashFloodWarning for the #ParkFire burn scar. The heavy rain may cause #DebrisFlow

Looks like another #DebrisFlow or rock slide on the 38. Angeles Oaks in the mountains above Yucaipa.

Anomalous pebble in layered #sedimentary #rock
An angular pebble is conformably surrounded by argillaceous and sandy layers in this #photograph of the #Neoproterozoic #Squantum Member of the #Roxbury Conglomerate. The wide range of clast sizes led to an interpretation as a #glacial #tillite thru the 1970s, but the Squantum Member is now mostly interpreted as a #debrisFlow (#debrite or #turbidite). My #photo.
