It did little to impact the region’s drought, but parts of San Diego County received a good drench Monday as monsoon humidity continued to produce raindrops during one of the driest months of the year.
The National Weather Service said Cuyamaca Lake received 2.32 inches of precipitation and Palomar Mountain received 1.10 inches during the 48-hour period ending at 2:45 p.m. Monday.
Forecasters said their primary and secondary stations also showed that the Oceanside areas received 0.28 inches to 0.98 inches of rain during the same period, with a point near Cal State San Marcos reporting 0.37 inches.
The rains that passed 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 registered just 0.01 inches. The city averages just 0.03 inches in July.
“The areas that received the rain will have a green on the vegetation, but it will not last long,” said Mark Moede, a forecaster with the weather service. “Things will dry up 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. This morning’s wet rain put a literal buffer on the sun’s ability to evaporate low-lying clouds.
“The drier air begins to move tonight through Tuesday, with only a small chance of afternoon storms especially in the mountains on Tuesday.”
Most areas of San Diego County have received half – or less – their normal rainfall, creating moderate drought conditions locally, forecasters said.
