Cold ocean air moved ashore before dawn Tuesday, triggering thunderstorms across San Diego County and generating ferocious winds that could return late Tuesday night, possibly affecting flights at San Diego International Airport early Wednesday. More than 220 flights were delayed on Monday when wind s gusting up to 45 mph repeatedly hit the airport’s sole runway. A wind advisory will be in effect from 8 p.m. Tuesday to 8 a.m. Wednesday. Airline passengers are advised to check their flight status. There have been 59 delays so far Tuesday. The turbulent air that produced 17 lightning strikes countywide just after midnight has temporarily settled down. At one point on Monday, winds were gusting 50 to 55 mph along a line that stretched from Poway to Point Loma, drawing an alert from the National Weather Service. The winds hit 60 mph on Mount Laguna, 59 mph in Julian and 48 mph in Ramona. The winds also temporarily knocked out power to about 800 San Diego Gas Electric customers, mostly in and around Julian and San Marcos. Forecasters say the winds are whipping up ocean waves that are expected to reach the 9- to 12-foot range this week at local beaches, potentially causing beach erosion.

A second wave will pass through from Tuesday night into Wednesday morning, bringing more rain and winds that could again reach the 30- to 45-mph range at the coast. As of 3 a.m. Tuesday, San Diego had recorded 8.94 inches of precipitation since the rainy season began on Oct. 1. It’s possible that the second wave of the storm will push the total to 9.79, the amount that the city averages in an entire year.

But scientists say the water is causing erosion along coastal bluffs, especially in the Torrey Pines area, raising the risk of rock and mud slides. 24-hour rainfall totals through 5:03 a.m. Tuesday: Lake Cuyamaca, 2.97 inches; Julian, 2.67 inches; Skyline Ranch, 2.07 inches; Mount Woodson, 2.01 inches; Pine Valley, 1.93 inches; Ramona, 1.84 inches; Barona, 1.83 inches; Lake Wohlford, 1.79 inches; San Diego Country Estates, 1.64 inches; Valley Center, 1.62 inches; Santee, 1.52 inches; La Mesa, 1.51 inches; Poway, 1.49 inches; Escondido, 1.46 inches; Kearny Mesa, 1.39 inches; Carlsbad, 1.37 inches; Otay Mountain, 1.35 inches; San Marcos, 1.34 inches; Fashion Valley, 1.18 inches; San Diego International Airport, 0.98 inches; Vista, 0.97 inches; Miramar, 0.91 inches; Ranchita, 0.86 inches; Campo, 0.85 inches; Brown Field, 0.78 inches; Montgomery Field, 0.77 inches; Point Loma, 0.76 inches; National City, 0.75 inches; Oceanside, 0.67 inches; Chula Vista, 0.65 inches; North Island, 0.55 inches; Borrego Springs, 0.21 inches. ...read more read less
