“The reservoirs are starting to get some stream flow so that should help bring levels up. The rains are also helping with groundwater. This storm will definitely help. We had storms in October and now this, so this is a really good start to the year. Hopefully it continues. Though, not too bad, we don't want flooding,” said a weather specialist for the National Weather Service.
The storm rolled ashore Monday in northern California, and police said it may have contributed to the death of a young man.
