Colusa County got its first real dose of winter weather this week as the strongest rainstorm yet of Water Year 2017-18 swept its way across the state.

According to the National Weather Service, much of the Sacramento Valley was expected to get up to two inches of rain from the storm, which was expected to last through Tuesday night or into Wednesday.

“Right now, we’ve got a lot of rain across the area, and certainly across all of Colusa County,” National Weather Service Meteorologist Craig Shoemaker said Monday afternoon. “This is the strongest storm that we’ve had so far this year, at least as far as rainfall and moisture.”

Early Monday afternoon, most of Colusa County had seen anywhere from three-quarters of an inch to an inch of rain, and Shoemaker said that the National Weather Service was still expecting quite a bit more.

“It could be up to another inch,” Shoemaker said. “We’re just about in the middle of this storm right now.”

Shoemaker added that Monday looked to be the start of a transition to a dryer weather pattern with a ridge of high pressure beginning to build, but that more wet weather could be in store for the next week.

“Unfortunately, this looks like the one big storm system that we’ll have for the week,” Shoemaker said. “We’ve got another system – we’re talking about maybe on Jan. 15 or Jan. 16 – that’s about another week away.”

This week’s rain was much needed in Colusa County, which was running anywhere from 40 to 50 percent its normal rainfall totals before Monday. Shoemaker said that this storm was likely to bring Colusa County towards about 75 percent of normal by the time it was done.

“We’ll get at least 25 percent of that back, of what we were below normal,” Shoemaker said. “That’s just speculating about where our final numbers will be, but somewhere in that range. This is a pretty significant rainfall event, given how dry we started the water year off as.”■
