...Periods of moderate to heavy rainfall next week resulting in 
rises on rivers and creeks along with potential for minor urban 
flooding...

A plume of subtropical moisture will become aimed at the Pacific 
Northwest Tuesday and Wednesday promoting mild conditions and 
periods of moderate to heavy rainfall. Temperatures for most 
elevations below 5000 feet will warm above freezing Tuesday and 
remain above freezing through Thursday morning leading to increased 
snowmelt. Rainfall amounts will be between one and three inches over 
the 48 hour period. Local rainfall amounts along the Cascade crest 
up to five inches.

The combination of snowmelt and rainfall will lead to excess runoff 
leading to rising creeks, streams, and rivers. At this time, main 
stem river flooding is not expected however several smaller 
tributaries could approach or exceed bankfull. 

Urban areas with blocked drainages may also experience minor 
flooding. Mud and rockslides will be possible in areas of steep 
terrain.
