SAN DIEGO – Rain pummeled San Diego early Friday morning, causing crashes and spinouts throughout the region, three of which shut down major freeways in Del Mar, Oceanside and Chula Vista.

At 3:41 a.m., a semi jackknifed on Interstate 5 south at Via De La Valle in Del Mar. A Sig Alert was issued just after 4 a.m., and at around 4:30 a.m., both sides of the freeway were completely shut down due to an oil spill, according to California Highway Patrol. Traffic was backed up for miles. 
Northbound lanes were fully reopened before 6 a.m. All but one southbound lane was reopened just after 7 a.m. 
Crews were waiting for a Caltrans truck with absorbent to arrive and clean up the oil spill. There was no estimate on when that would be complete. 
At 3:52 a.m., a CHP patrol SUV responded to a BMW that had been abandoned after spinning out on the right shoulder of northbound Interstate 805, north of Bonita Road in Chula Vista. While two officers were sitting in their SUV, a semi truck struck their vehicle and jackknifed across the northbound lanes, sending oil leaking onto the freeway. A Sig Alert was issued at around 4 a.m. Northbound traffic was backed up from Bonita Road to L Street for nearly two hours. It fully reopened at 5:50 a.m.
The two officers suffered head and neck pain.  
Meanwhile, at 7:35 a.m. a big rig truck jackknifed on Interstate 5 north near Harbor Drive in Oceanside. The semi truck spun out and rolled onto its side, according to the CHP Incident Information Page. A Sig Alert was issued at 7:48 a.m. Two of the five northbound lanes were closed. There were no reported injuries.  
Among the highest precipitation amounts captured by automated gauges in a 12-hour period ending at 8 a.m. were 1.05 inches of rain on Otay Mountain; .95 of an inch in El Camino Del Norte; .85 of an inch in Thousand Trails; .70 of an inch in San Miguel; .67 of an inch at Brown Field; .61 of an inch in La Jolla; .60 of an inch in San Marcos and Elfin Forest; .48 of an inch in Descanso; .41 of an inch in Alpine; .39 of an inch in Julian; and .36 of an inch at Lindbergh Field, according to the National Weather Service.
The NWS predicted cooler weather, a chance of showers and a slight chance of thunderstorms through tonight. A slight chance of showers is in Saturday's forecast.
"A slow moving low pressure system will bring periods of showers and isolated thunderstorms through early evening, decreasing during the weekend," according to the weather service.
The rain may lead to flooding, and a flash flood watch for the mountains and deserts will remain in effect from noon through this evening.
"Bands of heavier showers and isolated thunderstorms could cause local small stream flooding with isolated flash flooding possible," according to the weather service.
An urban and small stream flood advisory for the southwestern portion of the county expired at 7:15 a.m. and a wind advisory for the mountains and deserts expired at 5 a.m.
