A low pressure system moving in from the northwest will bring widespread precipitation tonight through Tuesday night. Highest precipitation amounts are expected across northern Orange County, western Inland Empire, and the San Bernardino Mountains, decreasing to the south and east. For storm total precipitation there is an 80-90% chance of 0.25" or more for areas near the LA County border, decreasing southward with a 35-40% chance of 0.25" or more over southern San Diego County, a 40-60% chance over the high desert, and 10% or less over the low deserts. Chances of 1" or more are around 40-60% on the coastal slopes of the San Bernardino Mountains, and 15-30% on the remaining coastal mountain slopes. Snow levels will fluctuate between about 7000-8000 ft, and small accumulations of snow are possible above 8000 ft. Isolated rainfall rates of 0.50-0.75"/hr are possible along the cold front north of San Diego County, leading to a threat of minor urban flooding as well as flash flooding and debris flows should such rates occur over the recent burn scars. $$
