Light rain fell on the Southland Monday morning, and thunderstorms are possible Monday afternoon, the National Weather Service said.
The precipitation, much of which hit the Central California coast Monday morning, is the result of a slow-moving upper-level low, said NWS meteorologist Curt Kaplan.
In addition to light rain after midnight, another round of rainfall is possible Monday morning, he said. But on the whole, the rain will be “spotty, a hit-or-miss affair,” nowhere near sufficient enough to produce debris flows, Kaplan said.
However, dry and wet thunderstorms are possible, and any dry thunderstorm, which occurs when the atmosphere is so dry that rain dissipates before hitting the ground, can trigger fires when accompanied with lightning, the NWS said. Any strong thunderstorm also could produce wind gusts of 50 miles per hour, the weather service warned.
The NWS forecast showers in L.A. County Monday and highs of 52 degrees on Mount Wilson; 62 in Avalon; 65 in Saugus; 66 in Palmdale, Lancaster and at LAX; 67 in Burbank; and 68 in Downtown L.A., Long Beach, Pasadena and San Gabriel.
Showers were also forecast in Orange County, along with highs of 45 on Santiago Peak; 55 on Ortega Highway at 2,600 feet; 61 in Trabuco Canyon; 63 in Fremont Canyon, Laguna Beach and San Clemente; 64 in Mission Viejo and Newport Beach; 66 in Yorba Linda; 67 in Anaheim; and 68 in Fullerton and Irvine.
Tuesday’s highs will be roughly the same, but amid cloudy skies.
