FLASH FLOOD WATCH: Monday-Wednesday

Another heads-up for us from the National Weather Service...

...A Flash Flood Watch is in effect from noon today through Wednesday afternoon for all of San Diego County, including our deserts.  …A large Pacific plume of moisture is expected to bring heavy rains and the potential for areas of serious flooding.

…Rainfall rates near or greater than one inch per hour are  possible at times...especially in the mountains. 

…Mud and debris flows area also possible...especially below steep   terrain and areas with little to no vegetation. 

…Runoff coming out of the mountains will fill and could overflow  streams on the desert slopes of the mountains...thus the deserts  are included in this flash flood watch. 

…Strong thunderstorms could accompany a cold front on Wednesday.   With the rainfall already received...this additional significant   rainfall will continue the threat of mud and debris flows...   Particularly in and around the recent burn areas. 

Precautionary/preparedness actions...  A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation.  You should monitor later forecasts and be prepared to take action should flash flood warnings be issued. 


STORM TOTAL NOON MONDAY:  1.34 in.
YEAR TO DATE: 5.64 in.
