It鈥檚 a little unusual; California typically starts to see atmospheric rivers later in the year, in November. Jonathan Garnder, the lead forecaster for the National Weather Service in Eureka, said the early-in-the-season storm could help fight fires burning along the California-Oregon border.
鈥淧otentially, it鈥檒l put them out, but if it doesn't put them out, then it will cause them to burn less intense and allow the firefighters to get a good handle on containing them,鈥� Garner said.
鈽� Rain is in the forecast for portions of interior through early Tuesday. It is expected to begin this afternoon over Shasta County with some sprinkles possibly making it down to Sacramento and the Interstate 80 corridor tonight. 馃導锔�

Garner added that Del Norte County, which is located along California鈥檚 northern border, was approaching drought status prior to this storm. He said the storm could help alleviate drought conditions there.
In a , UCLA meteorologist Daniel Swain said early season predictions that last winter鈥檚 heavy precipitation would mean a lighter fire season have been accurate.
鈥淩eally, the only part of California where fire season has gotten going at this point is northwestern California,鈥� he said. 鈥淭hese fires have been burning for a long time, they鈥檙e pretty big 鈥� although not extreme.鈥�
Rain could help air quality
Over the weekend, the Sacramento area and other northern parts of the state saw a decline in air quality due to smoke from fires burning along the California-Oregon border. Swain said the upcoming atmospheric river would be a primarily 鈥渂eneficial storm鈥� when it comes to alleviating those conditions.
鈥淭here are active fires burning, air quality has been really bad,鈥� he said. 鈥淭his is really going to help with those things.鈥�
If this storm is followed by another heavy rain event, Swain said it might bring the 鈥渆nd of fire season.鈥�
鈥淚 don鈥檛 think we can call it just with one rain event, but it definitely is going to help a lot and in particular, it鈥檚 going to dramatically improve air quality,鈥� he said.
Current forecasts predict the storm will likely linger into Tuesday morning, bringing light showers with it. The National Weather Service in Sacramento says impacts from the storm likely won鈥檛 be felt . Garner says residents should be cautious of potentially slick roadways, but that the impacts in urban areas will likely be minor.
