Areas Affected: Butte County, Central Sacramento Valley; Mountains Southwestern Shasta County to Northern Lake County; Northern Sacramento Valley; Shasta Lake Area / Northern Shasta County; Western Plumas County/Lassen Park; Clear Lake/Southern Lake County; Northeast Foothills/Sacramento Valley
The Flash Flood Watch continues for
* The following burn scar areas: Carr-Hirz-Delta fire burn areas in Shasta County, the Mendocino Complex burn area in Lake, Glenn, Colusa Counties, and the Camp Fire burn area in Butte County in Northern California.
* Through Monday afternoon
* Periods of heavy rain are forecast for Interior Northern California through Monday afternoon. Thunderstorms are possible during the afternoon and evening hours through Monday. Heavy rain from thunderstorms over a burn area can generate life threatening debris flows. If this occurs, the National Weather Service will issue a Flash Flood Warning for the burn areas.
Debris flows can be a dangerous situation. If you observe movement of soils, debris, or large amounts of water you should move to higher ground and away from the burn area immediately.
Residents, outdoor enthusiasts, and persons traveling or working within and downslope of the Carr-Hirz-Delta Fire burn areas, the Mendocino Complex burn area, and the Camp Fire burn area need to be alert for the potential of mud and debris flows. These flows could impact area roadways and hill sides, damage homes, and could block local streams and creeks. Do not try to cross flooded roadways or creeks. A debris flow of only a few inches deep can be powerful enough to move a vehicle off the road.
A Flash Flood Watch for a burn area means that conditions may develop that lead to flash floods, rock slides and/or debris flows.
