Rare July storm drenches parts of bone-dry greater San Diego
The monsoonal moisture won’t put a dent in the drought
It did little to impact the region’s drought, but parts of San Diego County got a good drenching on Monday as monsoonal moisture continued to produce shots of rain during one of the driest months of the year.
The National Weather Service says that Lake Cuyamaca received 2.32 inches of precipitation and Palomar Mountain got 1.10 inches during the 48-hour period ending at 2:45 p.m. Monday.
Forecasters say that their primary and secondary stations also showed that areas of Oceanside received from 0.28 inches to 0.98 inches of rain during the same period, and a spot near Cal State San Marcos reported 0.37 inches.
Passing storm cells also dropped 0.34 inches in Vista, 0.24 inches in Fallbrook, 0.17 inches in Valley Center, and 0.14 in Escondido. San Diego International Airport recorded only 0.01 inches. The city averages only 0.03 inches in July.
“The areas that did get rain will get a green-up in vegetation, but it won’t last long,” said Mark Moede, a weather service forecaster. “Things will dry out and there will be more fuel for potential wildfires.”
The weather service said in an advisory Monday that “most of the coast, including the valleys in San Diego County, have yet to see the sun today. The wetting rain of this morning put a literal damper on the sun’s ability to evaporate the low clouds.
“Drier air starts to move in tonight into Tuesday, with just a small chance of afternoon thunderstorms mostly in the mountains Tuesday.”
Most areas of San Diego County have received half — or less — of their normal rainfall, creating moderate drought conditions locally, forecasters said.
