The ongoing atmospheric river is expected to persist through
tomorrow as the Pacific cold front slowly presses inland. An
additional 2-5" of rainfall will maintain an excessive rainfall
threat through tomorrow morning along the Oregon coastline, and
along the Cascades given the degree of saturated soils in the
area. For more information regarding the Excessive Rainfall
threat, please visit wpc.ncep.noaa.gov.

The next Storm Summary will be issued by the Weather Prediction
Center at 700 PM PST. Please refer to your local National Weather
Service office for additional information on this event.
