Practice Your Pineapple Expression This Weekend

"Talking about rain... a LOT is coming starting Sunday, with the establishment of a significant pineapple express event," says UW meteorologist Cliff Mass. "And a super warm front." [UPDATE: "Atmospheric River."] His post is mainly about the squall line that blew through Wednesday morning, drenching the city, but the National Weather Service goes into a bit more detail. 

From Saturday night through Monday, we should be experiencing a pineapple express weather system, which besides dumping a lot of rain on us, will raise the snow level to 7,000 feet--adding some snow melt to the rain-swollen rivers in the area. It's not clear yet from the models where the intensity of the rains will be strongest, so stay tuned.

KOMO's Paul Deanno says it could be the wettest storm in two years, adding that "if the rain goes for 24 hours or longer, we'll probably be dealing with flooding on the Nooksack, Skagit, Stillaguamish, Snoqualmie, Satsop and Bogachiel Rivers. If the rain keeps going, even the more stubborn-to-flood rivers like the Chehalis and Cowlitz could go over their banks." On the bright side, the NWS advises that the flood risk for the Green River is minimal.
