March 10, 2021 (San Diego) - The San Diego County Department of Environmental Health and Quality (DEHQ) has issued a General Rain Advisory to avoid water contact at all coastal beaches and bays due to recent rainfall. Swimmers, surfers, and other water users are warned that rain brings urban runoff, which can cause bacteria levels to rise significantly in ocean and bay waters, especially near storm drains, creeks, rivers, and lagoon outlets. Urban runoff may contain large amounts of bacteria from a variety of sources such as animal waste, soil, and decomposing vegetation. Bacteria levels can remain elevated after a rainstorm depending upon the intensity of the storm, volume of runoff and ocean conditions. Many coastal storm drains have permanent warning signs; however, additional warning signs are not posted for General Rain Advisories. Water contact such as swimming, surfing and diving should be avoided during rain and for 72 hours following the rain event.

STORMS BRING HIGH WINDS, COLD TEMPERATURES AND SNOW AT LOW ELEVATIONS

East County News Service

March 10, 2021 (San Diego’s East County) – A multi-day storm is expected to continue today through Friday, with chilly temperatures and heaviest rainfall today. Snow could drop as low as 3,500 feet tonight and tomorrow, the National Weather Service predicts.

Treacherous travel and traffic delays are possible through mountain passes, including on I-8 in San Diego’s East County and I-15 in Riverside County due to freezing conditions and reduced visibility in snow and fog. Winds  with gusts up to 60 miles per hour could bring damage to temporary structures such as tents and canopies.

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.
