Deciphering Western Washington's forecast boundaries

Deciphering Western Washington's forecast boundaries

We sometimes get a few puzzled e-mails when we say something along the lines of "snow in the foothills" or "east Puget Sound lowlands" and people wonder, for example: "I live in X, is my city in the East Puget Lowlands?"

Cool maps to the rescue. Here are some guides to let you know who is where then when the Weather Service issues warnings, or when we give general forecasts:

PUGET SOUND AREA

(Cities include: Seattle, Tacoma, Bremerton, Shoreline, Bothell, Des Moines, Renton, Kent, Auburn, Tukwila, Puyallup, Gig Harbor, Port Orchard)

(** Note: Western Snohomish County cities like Everett, Lynnwood, Mukilteo and Edmonds sometimes trend more toward Northwest Interior weather, especially for wind, but for general forecast purposes, they are considered the Puget Sound region.)

NORTHWEST INTERIOR

(Cities include: Bellingham, Friday Harbor, Mount Vernon, Arlington, Burlington, Anacortes, Oak Harbor, Coupeville. ** Note: Everett, Stanwood, and Marysville are on the fringe here in that they sometimes get "Northwest Interior" type weather, and sometimes not, depending on how the winds align.)

EAST PUGET LOWLANDS (FOOTHILLS)

(Cities include: Bellevue, Kirkland, Redmond, Issaquah, Sammamish, Snoqualmie, North Bend, Enumclaw, Gold Bar, Buckley, Monroe, Snohomish, Black Diamond) ** Note: During snow forecasts where we say "snow in the foothills above 500 feet", this would exclude the areas right along Lake Washington. Check here for your elevation.

NORTHWEST INTERIOR

(Cities include: Bellingham, Friday Harbor, Mount Vernon, Arlington, Burlington, Anacortes, Oak Harbor, Coupeville. ** Note: Everett, Stanwood, and Marysville are on the fringe here in that they sometimes get "Northwest Interior" type weather, and sometimes not, depending on how the winds align.)
