The storm that darted through the region Monday night and early Tuesday pushed San Diego’s seasonal rainfall roughly three times above average, and another storm will arrive Thursday, the National Weather Service said.
San Diego International Airport has recorded 2.93 inches of precipitation since the rainy season began on Oct. 1. The average for that period is 0.88 inches.
The latest storm went unnoticed by many because it occurred at night, during which substantial rain fell. The airport received 1.07 inches, about what it averages for the entire month of November. Most of the heaviest rain fell west of Interstate 15, which is unusual this time of year.
The next system will arrive from the northwest and could produce showers as early as Thursday morning, forecasters said. The core of the storm will hit Friday and could produce rain into Saturday morning. Early projections indicate that the county could receive 0.50 to 1 inch of rain. Scattered showers could last until Saturday night, when the San Diego State University football team hosts San Jose State University at Snapdragon Stadium, beginning at 7:30 p.m.
