Washington Faces Days of Heavy Rain as Flood Watch Extends Through Thursday Across the Pacific Northwest
WASHINGTON — A widespread Flood Watch is now in effect through Thursday as rounds of heavy rain move across the Pacific Northwest, including Western Washington, the Cascades, the Olympics, and parts of the Idaho Panhandle. Officials warn that already saturated soils and rising rivers will make the region increasingly vulnerable to flooding and landslides throughout the week.
Flood Watch Covers Western Washington and the Cascades
Meteorologists report that the alert spans from Monday through Thursday for areas west of the Cascades, while the Idaho Panhandle remains under watch from Tuesday through Wednesday. The threat stems from persistent moisture streaming into the region, producing continuous rainfall.
The latest forecast shows:
- 2–6 inches of rain expected in the lowlands and foothills
- 6–10 inches of rain in the Cascades and Olympics below snow level
- A few inches possible in the higher terrain of the Idaho Panhandle
High Rivers and Saturated Ground Increasing Flood Risk
Because of substantial rainfall in recent days, many rivers across Western Washington are already running high. Forecasters warn that additional river flooding is likely, with some locations experiencing significant rises.
Landslides are also a growing concern, particularly in areas where steep slopes and waterlogged ground increase instability.
Olympic Rain Shadow May Reduce Totals in Some Areas
Forecasters note that a rain shadow effect from the Olympic Mountains may limit rainfall totals north of Seattle toward Bellingham, reducing the overall flood impact in those pockets. However, most surrounding counties remain under elevated risk conditions through mid-week.
