The county Department of Environmental Health has issued an advisory for all beaches in Del Mar, Cardiff by the Sea, Solana Beach and Encinitas due to recent rainfall, noting that rain can significantly increase levels of bacteria in coastal water. The department advises all residents to avoid swimming, surfing, diving and other aquatic activities for 72 hours after a rain storm.

Isolated showers are expected in San Diego County this morning before the storm system heads east this afternoon, NWS forecaster Miguel Miller said.

Moisture from Hurricane Rosa — now a tropical depression — brought light rain to the region Monday and Tuesday before a separate low-pressure system brought showers and thunderstorms Wednesday.

San Diego received less than one-tenth of an inch of rain over the last three days, Miller said.

The storm dropped one-tenth of an inch of rain in Escondido and Poway and nearly a quarter-inch of rain in Carlsbad over the last three days, Miller said.

The storm emanating from the remnants of Hurricane Rosa brought higher-than-normal surf levels to the coasts Saturday night, but the waves returned to normal by Tuesday, according to the National Weather Service.
