The National Weather Service has issued a Flash Flash Flood Watch for the Butte Wildfire Burn Area in Calaveras County through this evening.
Flash floods and debris flows will be a particular threat in and below the recent burn scars due to the potential for thunderstorms today.
Rainfall rates could exceed one quarter inch per hour with thunderstorms.
Recent burn areas typically absorb only small amounts of rainfall, leading to enhanced runoff, particularly when rainfall rates are heavy. Those traveling along roadways within the burn areas should be alert for possible road problems due to flooding, rock and debris flows.
This could quickly become a dangerous situation. Residents and persons living and traveling within the burn areas should remain alert and take action should heavy rain develop. A Flash Flood Watch for a burn area means that conditions, including the formation of thunderstorms, may develop that could generate heavy rainfall rates. Heavy rainfall rates over recent burn areas could lead to flash floods, rock slides and/or debris flows. This is a heads up product. Be prepared to take action.
Additionally, a Winter Weather Advisory remains in effect for the Sierra Nevada above 3500 feet until 7 AM Tuesday.
Snow accumulations will range from four to eight inches above 3500 feet and eight to sixteen inches above 7000 feet.
A Winter Weather Advisory means that periods of snow will cause travel difficulties. Be prepared for snow covered roads and limited visibilities and use caution while driving.
