The Pacific Northwest braces for a weather onslaught as a powerful storm system approaches late Tuesday. The National Weather Service warns of a rapidly intensifying low-pressure system, potentially dropping below 950 mb, triggering high winds, heavy rain, and mountain snow.
Cascade gaps may see damaging gusts capable of toppling trees and causing power outages. Coastal areas and the Olympics face 2–4 inches of rain, with localized flooding risks as an atmospheric river spreads moisture from Northern California to British Columbia.
The weather pattern will remain volatile throughout the week, with more disturbances expected. As temperatures climb toward seasonal norms, residents are urged to prepare for storm impacts and potential travel disruptions.
