The National Weather Service says a series of storms is supposed to hit California from Thursday through Saturday.
Cindy Mathews is with the weather service. She says this will not be a repeat of the rain and runoff that we had in early February.
"The term 'atmospheric river' is being applied to this weekend's storm, but it is not one of the extreme ones," says Mathews. "Snow levels will start out at pass levels and fall to below 5,000 feet by Saturday. So, it's a moderate-type atmospheric river."
She also says a second storm could arrive Tuesday.
"In the spring time we have a little bit of trouble because the jet stream is trying to move its way farther to the north," says Mathews. "But, as we're forecasting when it's moving to the north, the models have a harder time hanging on to it because it might not actually follow the path we're telling it it should."
Reservoir operators have been releasing water to make room for the storms. They will continue to release water in an attempt to stay ahead of the snow runoff that will occur when the temperatures warm.
