A fast-moving storm out of the west Pacific will produce heavy rain across San Diego County Monday, slowing morning freeway traffic and making outdoor work a challenge.
The system also will likely drench faculty members who plan to be on strike at San Diego State University and Cal State San Marcos as part of a labor contract protest that will affect the entire California State University system.
The comparatively warm storm will reach the coast between 7 a.m. and 9 a.m., where it is expected to drop from 0.50 inches to 1.25 inches of rain by late afternoon, the National Weather Service said. Areas generally east of Interstate 15 could receive 0.75 inches to 1.50 inches of precipitation while mountain areas should get about 2 inches. Significant snowfall is not expected.
A flood watch will be in effect throughout the county from 9 a.m. to 9 p.m.
“There could be urban street flooding in many areas,” said Mark Moede, a weather service forecaster.
The storm is expected to largely clear to the east by late Monday night, although scattered showers are possible early Tuesday. Monday’s daytime high in San Diego will be 63, which is 4 degrees below average.
The storm will be significantly larger than the one that spread rain across the entire county on Saturday and the early part of Sunday. That system dropped 1.66 inches of rain on Palomar Mountain through 11:30 a.m. on Sunday, and 1.58 inches in Fallbrook. Carlsbad recorded nearly 1 inch of rain while San Diego International Airport received 0.57 inches.
