Widespread rain falling over San Diego County

SAN DIEGO -- Summer seemed to be in a hurry to make its exit Tuesday as dark and unsettled skies doused the San Diego area with unseasonable on-again, off-again showers.

The modest precipitation two days shy of fall's start was mostly courtesy of former Hurricane Paine, reduced to a tropical depression off the coast of northern Mexico and destined to expire Wednesday in the Gulf of California, according to the National Weather Service.

Over a 24-hour period ending at 4 p.m., the NWS reported, the wet atmospheric system brought 0.8 of an inch of moisture to the Palomar Mountain area; 0.76 at Birch Hill; 0.71 in Descanso; 0.64 in Alpine; 0.6 in Julian; 0.56 at Lake Cuyamaca in Pine Valley; 0.45 at Brown Field airport; 0.3 in El Cajon; 0.29 in Chula Vista; and 0.28 in La Mesa.

Other precipitation totals included 0.2 of an inch in San Ysidro; 0.16 in Fallbrook, the Lake Murray neighborhood, Ramona and Rancho Bernardo; 0.14 in Oceanside; 0.13 in Carlsbad, Kearny Mesa, Point Loma and Poway; 0.12 in Bonsall, Serra Mesa and Valley Center; 0.11 in City Heights and Mission Valley; and 0.08 in Elfin Forest and at Miramar Lake.

The rainfall was expected to largely taper off Tuesday evening, with a chance of afternoon showers and thunderstorms lingering into midweek.

Thursday will be breezy and cooler, followed by a warming trend and weak Santa Ana winds Friday through Monday, meteorologists said.
