The National Weather Service has trimmed projected rainfall from the storm that’s expected to hit San Diego County on Wednesday and Thursday. But forecasters say a substantial system will hit the region, further lowering wildfire danger throughout the county.
On Monday, forecasters projected that coastal areas would receive from 1.5 inches to 2 inches of rain, with slightly lower amounts across inland valleys and foothills.
The weather service now says the latest computer models show that the storm will drop from 1’’ to 1.5” along the coast, and a bit less inland.
“It looks like the storm is going to carry more of its moisture down into northern Baja California than into San Diego,” said Mark Moede, a weather service forecaster. “This is mostly an offshore system that will reach the coast.”
Moede says it appears that the precipitation will begin falling late Wednesday morning in the Camp Pendleton-Oceanside-Fallbrook area, then spread out across the county. The heaviest rain will occur during the day and early evening. The system is expected to produce showers on Thursday.
San Diego will have a high of 65 and a low of 57 on Wednesday, and a high of 65 and low of 56 on Thursday. Ramona will have a high of 60 and a low of 51 on Wednesday, and a high of 58 and low of 45 on Thursday. Friday night’s temperature could drop to 39.
