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.

FOR THE LATEST UPDATES ON CONDITIONS, SCROLL DOWN TO THE NEWS TAB BELOW.

Power Outages

Power outages can happen for a number of reasons, typically a fallen tree or too much snow/ice buildup on powerlines. The City does not own or manage these powerlines. Please call Puget Sound Energy (PSE) at 1-888-225-5773 to report outages and learn about service restoration. Customers can also view PSE's outage map with estimated power restoration times at www.pse.com/outage/outage-map. For more information, visit our article on Power Outages.

Excessive Rain and Increased Landslide Risk

Landslides develop during intense rainfall, runoff, or rapid snowmelt. The earth can move rapidly, sometimes with little or no warning. Mercer Island sees about 5-15 slides each year. To report a non-life-threatening landslide, call our regional, non-emergency 24-hour dispatch center (425) 577-5656. In the case of an emergency call 9-1-1. Visit our Landslide Safety article for more information.

Ice and Snow

The Public Works Department's goal is to provide sanding, plowing, and de-icing services on public streets when winter weather brings snow and ice, in order of priority. Private streets are not maintained or plowed by the City. Click here to view the map of privately maintained streets.

In addition to plowing and sanding, crews often apply a pre-treatment of liquid deicer (see map) to other arterials located on steep hills and major intersections to help prevent minor ice build-up and make streets easier to plow. If compacted snow has already built up on the roadway, this deicer is less effective.

The City has six plows, three of which have sander units; one truck is used mostly for liquid de-icing. Follow this link for more information on the City's Snow and Ice Response Plan.
