Eugene, OR – Oregon begins the morning under thick clouds as rain taps rooftops and darkens roadways across the Willamette Valley. Puddles expand quickly, leaves clog storm drains, and rivers begin a steady rise.
According to the National Weather Service, a Flood Watch is in effect from late tonight through late Friday for Eugene, Portland, and much of western Oregon. The alert comes as a strong Pacific system delivers periods of heavy rain, with 1 to 2 inches possible in the Eugene area, and higher totals in nearby foothills.
Rain increases through Thursday morning and becomes steady by afternoon. Gusty winds accompany heavier bands, pushing moisture inland and accelerating runoff. Urban areas, small streams, and poor-drainage locations face the highest flooding risk first.
Travel impacts are expected to grow as rain persists. Drivers along I-5, OR-126, and local surface streets should watch for standing water, reduced visibility, and slick pavement. Creeks may rise quickly near roadways, especially after dark.
Temperatures remain mild in the upper 40s to near 50, keeping precipitation as rain for now. However, saturated ground from earlier storms means flooding could develop faster than usual. Meteorologists note rivers across western Oregon may approach minor flood stage by Thursday night into Friday.
By Friday, rain continues with little break. Low-lying farmland, basements, and underpasses remain vulnerable. While widespread major flooding is not expected, localized flooding could disrupt commutes and holiday preparations.
Looking ahead to Christmas travel weekend, rain lingers into Saturday before easing slightly. Conditions remain unsettled, signaling an active winter pattern settling in across the Pacific Northwest.
What you should do now:
Clear storm drains. Avoid flooded roads. Allow extra travel time.
