The steady, moderate rain overnight and into Friday morning has produced rainfall totals of more than an inch throughout the Sacramento region, unofficially making the month one of the top five wettest Octobers on record.
As of 9 a.m., 1.28 inches of rain had been recorded in 24 hours at the official rainfall gauge for Sacramento near Sacramento State. Other spots did even better: 1.45 inches in Auburn, 1.72 in Lincoln, 1.53 in Loomis, 1.29 in Roseville, 1.42 in Orangevale, 1.37 in Rio Linda, 1.45 in Fair Oaks and 1.29 in Elk Grove. Folsom Lake got 1.18 inches.
The rain and wet pavement played havoc with the morning commute, producing spinouts on surface streets and highways, including an 8:30 a.m. crash on northbound Interstate 5 at the West El Camino offramp that knocked down a light pole.
More rain was expected through Friday morning as the warm storm slowly moves through Northern California. The afternoon is expected to be drier.

But the rainfall won’t end there. A colder low-pressure system is expected to drop down from the Gulf of Alaska, bringing heavier precipitation Saturday night, according to the National Weather Service. The system is expected to bring lower snow levels and significant snowfall to the Sierra Nevada. Travel in the mountains could be difficult.
Looking ahead to Halloween, forecasters say that another Pacific storm is expected to push onto the Northern California coast by Monday afternoon or night. There’s a chance that prime evening trick-or-treat time could be dry.
