We're monitoring known trouble spots, but we can't be everywhere at once. We really appreciate everyone who pitches in to clear drains during storms - it really does make a difference.

A typical storm drain in Seattle, not quite clear of leaves but close.

Have a few minutes to spare? Clearing leaves out of storm drains near your home or business can really help reduce localized flooding.

As another round of heavy rain approaches: report flooding on streets or sidewalks by calling us anytime at 206-386-1218.

A prolonged atmospheric river will continue impacting the Pacific Northwest with heavy rainfall. Widespread significant river flooding is underway and is expected to continue through much of the week.

It will be critical to monitor the forecasts now and through the next seven days at weather.gov.

A snowy Central District streetscape in 2020.

It's simple: make a plan to keep sidewalks near your home or business clear of ice and snow. Now is the time to find that snow shovel and buy de-icer.

If a winter storm hits, we will work to keep routes to hospitals, schools, and other essential community destinations open.

You don't need THIS MUCH de-icing material to keep sidewalks clear. NOW is the time to get de-icer & a snow shovel to prepare for ice and snow we might have.
