The National Weather Service has issued a winter storm warning for much of Puget Sound.

The warning covers the Central Sound area from Tacoma to Everett — including Bainbridge Island, Bremerton and Seattle — and will be in effect from 6 p.m. Sunday to 4 p.m. Monday.

Up to 6 inches of snow is possible, and forecasters said up to 8 inches of snow may fall close to the Cascades.

The snow is expected to increase Saturday evening and continue off and on through early Monday afternoon.

Forecasters predict the main impact may be on travelers, with snow-covered streets and roads. Travel is expected to be especially difficult on the Monday morning commute, and the National Weather Service is recommending only traveling in an emergency.
