SEATTLE, Washington – The first light glimmers through heavy, low clouds, reflecting on slick pavement as another Pacific storm churns ashore. The hum of traffic blends with the steady rhythm of rain — a familiar November sound across western Washington.

The National Weather Service in Seattle warns of flood potential for King County, particularly along the Snoqualmie River, through Friday evening. Total rainfall from this system could reach 2 to 2.75 inches, with snow levels falling sharply from 6,000–7,000 feet to around 3,500 feet by Friday morning. This mix of heavy rain and mountain snowmelt could cause rivers to rise rapidly, with minor flooding possible in low-lying and flood-prone areas.

Drivers along I-5, Highway 2, and local river crossings should allow extra time for travel. Water may pool on roads during peak rainfall, and visibility will drop sharply during heavier showers. Residents near creeks or floodplains should monitor local alerts and avoid crossing flooded intersections.

After a damp start to the weekend, conditions will steadily improve. Saturday brings a brief break, with partly sunny skies and highs near 56°F. Sunday will be milder, topping 61°F, before another weak front reintroduces light rain on Monday.

Despite this stormy stretch, forecasters note it’s typical for early November — the region’s wettest time of year. Long-range models hint at a cooler, drier trend closer to Veterans Day, with a possible “Winter Tease” midmonth as Arctic air edges south.

For now, western Washington braces for another classic late-fall deluge — gray skies, wet commutes, and the steady pulse of rivers rising toward their November rhythm.
