Here is the Base radar image off of the NWS website. As you can see we have a pretty good weather system coming in today. Take a look at these 2 Terminal Forecasts for the winds!

I thought this was a pretty good radar image that shows the shadow caused by the Olympic mountains. You can see south of Port Angeles and west of Bremerton there is no rain echos from the radar. But more than likely it is raining. Just the mountains getting in the way of the weather radar up on Camano island (ATX)
