The National Weather Service has issued a flood watch for Linn County through Thursday night, Dec. 11.
According to the NWS, heavy rain that arrived Monday signalled the beginning of several days of heavy rainfall expected to impact northwestern Oregon and western Washington through late Thursday night.
The precipitation is the result of a “potent trans-Pacific jet stream” that will move sub-tropical moisture from the Pacific, resulting in heavy rainfall at times and warmer-than-normal temperatures.
