WHATCOM COUNTY, Wash. — National Weather Service forecasters in the Seattle office continue to expect the arrival of an unseasonably very wet weather system later this week but have dialed-back the expected amount of rainfall for the northern Cascade Mountain range.
An unseasonable and very wet frontal system in the form of an atmospheric river will move through the area Thursday and Friday. 1-3″ of rain is expected in the mountains during this time. No rivers are currently forecast to reach flood stage but a few flowing off the north and central Cascades could get close Friday or Saturday.
After a relative lull in precipitation Friday, a second frontal wave is expected to arrive Saturday bringing another bout of unusually heavy precipitation to the area. Rainfall amounts with this system continue to look lighter than Thursday’s rainfall, but still significant. The cumulative affect remains helping to keep rivers running high through Saturday and into Sunday.National Weather Service Seattle office (June 7, 2022)
The snow level is expected to be “well above 11,000 feet” on Thursday, resulting in mountain precipitation falling as rain, not snow.
