Flood season has arrived
A moderately strong atmospheric river is forecast to hit the region through Saturday, Nov. 1. 2025, bringing heavy rain at times.
Snohomish County rivers are expected to rise, although widespread flooding isn’t forecast. The U.S. National Weather Service issued a hydrologic outlook encouraging vigilance. “Some uncertainty remains over rainfall amounts. River conditions will continue to be monitored closely the next couple of days,” the Weather Service said.
Meanwhile, more wet weather is expected next week.
History shows that we are entering the peak time for weather that can bring flooding here. It pays to regularly visit the flood page on the Snohomish County Public Safety Hub for quick access to key resources, including river gauges, interactive maps, alerts and other tools. https://bit.ly/snocoflooding

Snohomish County Surface Water Management has added river-gauge notifications to its Real-Time Flood Information Center.
Anyone can sign up for text or email notifications that alert when any of the river gauges in the county reach flood phases 2 through 4. River gauge notifications are informational and based on real-time conditions without forecasting future flood scenarios.
To sign up, go to https://snohomish.onerain.com, click “Subscribe to Flood Notifications”, select which river basin you are interested in, then select the gauge and phase.

For two decades the Snohomish County Hazard Mitigation Plan has helped guide community efforts to limit harm from natural and human-caused hazards. The 2025 update was recently completed and is now being reviewed. As in past years, the project team used best-available data to rank hazard risk. Earthquakes remain the County’s most-significant natural hazard, but there have been changes in how other risks stack up, and a new hazard has been added to the mix.
