SAN DIEGO -- Rain and mountain snow began to ease up Monday morning as a cold front was moving out of the region, but gusty wind is expected in parts of San Diego County into the afternoon while cooler weather and high surf are in the forecast through Tuesday.
In a one-day period ending around 4:15 a.m. Monday, automated gauges recorded 1.04 inches of rain on Palomar Mountain; .67 of an inch in Julian; .58 of an inch in Descanso; .47 of an inch in Alpine; .46 of an inch at Mt. Woodson; .29 of an inch in Poway; .27 of an inch in Ramona and Potrero; a quarter-inch in Escondido; .24 of an inch at Miramar and in Rancho San Diego; .23 of an inch in Rancho Bernardo and Oak Grove; and .20 of an inch at Brown Field and in Valley Center. Less than two-tenths of an inch was recorded in several other locales.
"Showers are departing this morning just as quickly as they came,'' according to the weather service. "Aside from a few stray light showers -- one moving off the San Bernardino Mountains into the northern Coachella Valley and a couple over San Diego County -- (precipitation) looks to be over.''
A National Weather Service winter weather advisory for the mountains expired at 3 a.m. Monday. However, a high wind warning for the mountains and deserts will remain in effect until 1 p.m. West winds of 35 to 45 miles per hour and gusts up to 65 mph are expected throughout the remainder of the advisory period.
Peak wind gusts recorded between Sunday evening and this morning were 71 mph at Volcan Mountain; 60 mph on Palomar Mountain; 59 mph in Borrego Springs and Harrison Park; 55 mph in Boulevard and Ocotillo Wells; 54 mph in Carlsbad; 50 mph in In-Koh-Pah; 47 mph in Del Mar and on Mateo Ridge; 46 mph at Silver Strand Beach; and 45 mph on Otay Mountain. Gusts of less than 45 mph were noted in numerous other areas.
Forecasters said the wind may lead to hazardous driving conditions, especially for motorists in high-profile vehicles. Visibility on some desert roadways may also be reduced due to blowing dust. The winds may also be strong enough to damage trees, signs and power lines.
Big waves are expected along the beaches as a large northwest swell develops Monday, and a high surf advisory will remain in effect until 2 p.m. Tuesday. Surf of 4 to 7 feet and sets to 9 feet will be possible south of Del Mar.
Cooler weather is also expected in San Diego County today and Tuesday with frost possible in the valleys each night, according to the NWS. High temperatures of 5 to 15 degrees below average are forecasted, but a gradual warm-up is expected Wednesday.
