The National Weather Service is forecasting an early season storm system to move through the area from late Monday through Tuesday. Total rainfall amounts are expected to range from 0.75 inches to 1.50 inches for the coastal and valley areas. One to three inches of rain could occur in the foothills and mountains. Snow accumulation is possible in the northern mountains above the 6,000 foot elevation. Strong southerly winds will accompany the storm front.

Most of the rainfall is expected to occur between Monday night and Tuesday afternoon. The heaviest rain is expected between 12:00 a.m. and noon on Tuesday, producing rates up to 0.5 inches per hour. However, there is a 30% to 40% chance of thunderstorms expected with this event, which could result in higher sub-hourly rain rates. Thunderstorms could result in higher 15 and 30 minute intensities, with rates exceeding 1.0 inch per hour. These higher intensities could exceed the established post-fire debris flow thresholds for the Mountain Fire burn scar, with the highest chances occurring in the South Mountain area.
