Steady rain on Sunday morning will become heavy later in the day, according to the National Weather Service. The heavy rainfall may lead to flash flooding and debris flow, along with the threat of urban and small stream flooding throughout the region, according to forecasts.
Rainfall could meet the thresholds for debris flow in the area of the CZU Lightning Complex fires that scorched 85,500 acres, destroyed nearly 1,500 buildings and killed one person just over a year ago. Debris flow is a risk in sloped areas following a large wildfire and can cause more injuries than the wildfire itself, according to the county.
