San Diego flash flood watch

FLASH FLOOD WATCH: ATMOSPHERIC RIVER BRINGING HEAVY RAIN AND SNOW

By Miriam Raftery

January 28, 2021 (San Diego’s East County)—A flash flood watch has been issued for San Diego County’s mountains, valleys and coatstal areas from 7p.m. Thursday to 4 p.m. Friday due to an atmospheric river moving across Southern California . The storm is forecast to bring widespread moderate to heavy rain and snow, with flash flooding possible.  If you encounter a flooded roadway, the Sheriff advises to "turn around, don't drown" since only a few inches of swiftly flowing water can quickly carry a vehicle into deeper water and submerge it.

Deep snow accumulations in the mountains will lead to difficult travel and chain restrictions for vehicles.  The storm is forecast to drop two to five inches of snow in local mountains. Snow levels are expected above 5,000 feet Thursday, dropping to as low as 4,500 feet by Friday. There is also a chance of thunderstorms, according to meteorologist Samantha Connolly with the National Weather Service.

FLASH FLOOD WATCH ISSUED

 

February 27, 2017 (San Diego)--The National Weather Service has issued a Flash Flood Watch for the coast, valleys and mountains of San Diego County below 5000 feet for late this morning into this evening.

A low pressure system from the northwest will tap a plume of subtropical moisture directed into northern Baja to bring periods of locally heavy rainfall from late this morning into early this evening. The most significant rainfall is expected from central and southern San Diego County into northern Baja.
