The San Diego area faces a 20 percent chance of thundershowers Sunday, and authorities advised residents to turn of sprinklers and avoid swimming because of potentially harmful runoff.
The National Weather Service forecast for the region calls for partly cloudy conditions with highs from 78 along the coast to 87 inland. The chance of a thunderstorm rises to 50 percent in the inland valleys and mountains.
The county Department of Environmental Health warned residents to avoid swimming and diving in coastal waters for 72 hours. Bacteria levels can rise significantly in ocean and bay waters, especially near storm drains, creeks, rivers, and lagoon outlets that discharge urban runoff.
Saturday’s thunderstorms dumped over an inch of rain on many areas of San Diego, breaking records and triggering the rule to turn off sprinklers for 48 hours. The San Diego County Water Authority notes that as a practical matter, irrigation systems can be left off for much longer after a significant rain event.
Because of the continuing chance of rain, the San Diego Symphony‘s free concert scheduled for Sunday at the Spreckels Organ Pavilion in Balboa Park was postponed. The concert will be rescheduled at a date to be announced later.
The moisture from the remnants of Tropical Cyclone Dolores off Baja California will continue to affect the San Diego area into Monday morning, according to the weather service.
