Rainstorm douses San Diego

SAN DIEGO — A blustery autumn storm doused the San Diego area with steady rains Thursday for a second straight day, dropping an inch or more of additional moisture in some areas and occasionally illuminating the skies with flashes of lightning.

The inclement atmospheric system — which caused scattered street flooding across San Diego County and prompted a three-hour airport-weather warning for Lindbergh Field — was expected to keep producing local showers overnight, according to the National Weather Service.

As of 4:30 p.m., the weather service reported, the ceiling of heavy wet clouds had generated two-day precipitation totals of 2.22 inches in Oceanside; 1.7 at Birch Hill; 1.52 at Henshaw Dam; 1.51 in Mesa Grande; 1.49 at Palomar Observatory; 1.37 in Fallbrook; 1.29 in Bonsall; 1.24 in Oak Grove; 1.23 in Rancho Bernardo; 1.18 in San Onofre; 1.14 in Del Luz and Mission Beach; 1.11 in Julian; 1.08 at Volcan Mountain; 1.07 at Lake Cuyamaca and in Valley Center; 1.05 at Miramar Lake; 1.03 in La Jolla and Ramona; and 1.01 in Escondido, Santa Ysabel and University Heights.

Other 48-hour tallies included 0.99 in Point Loma; 0.97 in Barona; 0.96 in Carlsbad and Ranchita; 0.94 at Lindbergh Field, where the thunderstorm- and wind-related alert was slated to be in effect from 4 p.m. to 7 p.m.; 0.95 at Mount Laguna; 0.93 in Del Mar; 0.91 in Poway; 0.89 in Scripps Ranch and Warner Springs; 0.88 in Campo; 0.87 in Santee; 0.86 in Kearny Mesa and Pine Hills; 0.85 in Mission Valley; 0.84 in Rincon Springs and Serra Mesa; 0.83 in Flinn Springs; 0.82 in Vista; 0.77 in Chula Vista and Warner Springs; 0.76 in Pine Valley; 0.75 at Brown Field airport; 0.72 in Dulzura; 0.7 in San Ysidro; 0.68 in San Marcos; 0.65 in El Cajon; 0.64 in Borrego Palm Canyon; 0.63 in Descanso; 0.55 in Alpine and San Felipe; 0.48 in Agua Caliente and Elfin Forest; 0.42 in Borrego Springs; and 0.27 in Ocotillo Wells.

A flash-flood warning was scheduled to be in effect for the southwestern section of the county until 8:30 p.m. the weather service advised.

The storm — the second to sweep through Southern California in a week — should dissipate and move out of the region by daybreak Friday, meteorologists reported.

The weekend is expected to usher in a warming trend, but another low- pressure system out of the northwest is due to deliver cooler temperatures and more chances of rain on Tuesday, according to forecasters.
