Winter Storm Ready

Share on Facebook Share on Twitter Share on Linkedin Email this link


Weather in the Pacific Northwest can be tricky to navigate. That "mostly sunny" winter day can easily turn into a downpour, or even a slushy snowstorm with short notice, which is why we've created this Winter Storm Ready information page. The City has consolidated the information residents, business owners, and visitors need to safely navigate Mercer Island throughout winter storm season.

Power Outages

Excessive Rain and Increased Landslide Risk

Landslides develop during intense rainfall, runoff, or rapid snowmelt. Mercer Island sees about 5-15 slides each year. To report a non-life-threatening landslide, call our non-emergency 24-hour dispatch center (425) 577-5656. In the case of an emergency call 9-1-1. Visit Landslide Safety for more information.

Ice and Snow

The City provides sanding, plowing, and de-icing services on public streets, in order of priority (private streets are not maintained or plowed by the City). Crews also may apply a pre-treatment of liquid deicer (see map) to arterials located on steep hills and major intersections. Click here for information on the City's Snow and Ice Response Plan.
