San Diego's 2016-17 rainy season was wetter than average

The mammoth storms that pummeled Northern California last winter, ending the drought, largely skirted San Diego County. But the region still ended up with above average rainfall for the season.

The National Weather Service says that San Diego International Airport recorded 12.73 inches of precipitation during the yearlong season that ended on Sept. 30. That’s 2.39 inches above average.

The differential was even greater at Ramona Airport, which got 22.96 inches of rain, a figure that is almost seven inches above normal.

The rainy season extends from October 1st of one year until Sept. 30 of the next.

San Diego would have had a basically average year if not for the storm that walloped the entire region on Feb. 27. The city’s main airport recorded 2.34 inches of rain — a figure higher than Lindbergh Field averages for the entire month of February.

On that same day, Ramona recorded 5.05 inches of rain, which caused widespread flooding.

The Feb. 27 storm took the form of an “atmospheric river” of moisture that flowed through Southern California.

Northern California was hit by a series of those rivers throughout the winter, producing one of the wettest years on record. The Sierra Nevada was buried in snow, much of which eventually flows into huge reservoirs in the northern part of the state.

Federal forecasters say it appears that there’s a chance that Southern California will have below average rainfall this winter. But Steve Harrison, a weather service forecaster, cautioned, “It’s very difficult to come up with a good forecast for a season.”
