The light, steady precipitation that began early Monday is coming from the remnants of Hurricane Paine, FOX 5 weathercaster Chrissy Russo said. So far, it has brought modest rainfall, and the showers are expected to continue, possibly into early Thursday morning, Russo said.
Over the next 48 hours, the areas most likely to receive measurable rain are in the South County, Russo said. Models predict that Otay Mesa will receive 0.3 inches, North Island will get 0.4 inches, 0.35 inches will fall in downtown San Diego, Kearny Mesa will get another 0.18 inches and El Cajon will nearly 0.5 inches. That's on top of the precipitation already recorded on Monday and Tuesday.
Over a 24-hour period ending at 4 p.m. Tuesday, the National Weather Service 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 Wednesday evening, with a chance of afternoon showers and thunderstorms lingering into midweek, Russo said.
Thursday will be breezy and cooler, followed by a warming trend and weak Santa Ana winds Friday through Monday, meteorologists said.
