A major storm could hit the Puget Sound region next week, dumping heavy rain on the area. The Snoqualmie River Basin is expected to miss the worst of it, according to forecasts by the National Weather Service.
The heaviest rain is expected to hit the Olympic and North Cascade mountains, said Dennis D’Amico, a Seattle-based meteorologist with the National Weather Service.
A massive, moist low-pressure front is headed for the area from Asia following the traditional Pineapple Express path.
The source is a typhoon in Asia, according to Cliff Mass, a University of Washington meteorologist.
“The monster storm, huge in scale and possessing hurricane force winds, will produce giant waves — greater than 50 feet high,” he writes on his blog.
Mass predicts the North Cascades and Olympics could receive 5-10 inches of rainfall on Tuesday.
Based on weather models, the storm isn’t likely to shift location, D’Amico says. “We’re not expecting flooding” in the Snoqualmie River Basin.
Accuracy for forecasts increases significantly as time gets closer to the event, and the National Weather Service will continue monitoring the storm’s progress, he says.
This winter is expected to be a La Nina year, which is more likely to be wet and cold. That means increased risk of flooding along Snoqualmie River.
