Seattle is bracing for a significant Pacific storm set to bring heavy rain and strong winds, anticipated to make landfall late Saturday night and persist throughout Sunday. The storm, characterized by a deep low-pressure center, is expected to draw moisture from the Pacific Ocean into the Pacific Northwest, resulting in substantial rainfall and increased wind speeds. Forecasts predict rainfall totals of up to 2 inches in some areas, potentially leading to localized flooding, while wind gusts could reach up to 40 mph, posing hazards to drivers and potentially causing power outages.
