Rainy weather expected through Monday; beaches closed due to bacteria-laden runoff

SAN DIEGO (KUSI) – 1:40 p.m. – County health officials urged beachgoers Monday to avoid contact with the ocean water due to weekend rain that likely carried bacteria-laden runoff into the ocean via storm drains.

 According to the county Department of Environmental Health, contact with coastal waters should be avoided for 72 hours after rainfall. 

The rain also prompted authorities to ban swimming at Tijuana Slough National Wildlife Refuge and Border Field State Park. The downpours sent sewage- fouled runoff from the Tijuana River into the surf, according to the county Department of Environmental Health.

Signs warning of contamination hazards will stand between Seacoast Drive and the border until follow-up testing determines the areas are safe for recreational use, county officials said.

Monday 8:56 a.m. – Cold and cloudy conditions, including occasional showers, are expected to continue in San Diego County through Monday. 

The chance of showers goes through Monday afternoon, with a 70 percent chance of measurable precipitation in the mountains and valleys, a 60 percent chance near the beaches, and a 20 percent chance in the deserts.   

Forecast stated, high temperatures Monday are forecast to be 70 to 75 degrees along the coast, 69 to 74 degrees in the western valleys, 62 to 67 degrees near the foothills, 56 to 63 degrees in the mountains and 74 to 79 degrees in the deserts.  

The rain is expected to clear up by Monday night. Warmer, drier weather is expected to develop mid-week followed by hot weather next weekend, forecasters said.

Sunday received record braking rain, of .58 of an inch, on Palomar Mountain, which topped the previous record for an October 4th of .03 of an inch, set in 1966. The .05 of an inch in El Cajon also set a record because no rain had previously been collected on an October 4, according to the National Weather Service.   

Sunday 12:26 p.m. –  The official rainy season started Sunday in San Diego County, as showers and mild winds hit the region.

The rain began before dawn and by 10 a.m., 0.15 inches of rain were recorded at Lindbergh Field, the National Weather Service said.

More water was collected not too far inland, as .31 inches were reported in Kearny Mesa. Rainbow Camp, between Pala and Fallbrook, received the most morning rain, with .94 inches.

According to California Highway Patrol, there have been reports of hydroplaning vehicles, dangerous conditions and crashes.

Drivers are instructed to slow down and use caution while driving on wet freeways, according to CHP.

The Miramar Airshow announced planes will continue to fly, regardless of the conditions.

The NWS said ocean conditions were warm — low 70s — and the surf was low, about 2-4 feet. Southwest winds were less than 10 miles per hour.

The NWS expected showers to continue through tonight and fade away by Monday afternoon.
