Classical or Jazz FM stations-Bainbridge/Seattle?

I'm thinking of relocating to the Seattle WA area--maybe to Bainbridge Island specifically. I'm wondering if there are any great FM Classical or Jazz stations out there? Hopefully commercial free, but with a strong enough signal that would cover a large area. In my area (Boston) I'm hooked on WGBH radio--incredible & adventurous classical programming during the day, & Jazz programming ("real" jazz, not "Smooth jazz") all night. Thanks for any tips!
