WSDOT operates low power radio stations at many mountain passes. These are typically at AM 530 kilocycles. They also broadcast traffic information and construction schedules.
Current Conditions and Forecast from NOAA
The US National Weather Service (NWS) is part of the National Oceanographic and Atmospheric Agency (NOAA). Visit their sites for current information and additional satellite views and raw current weather data. The geostationary satellite page (http://www.goes.noaa.gov/) has lots more images from other angles plus time-lapse MPEG movies you can download.
That's the good news. The bad news is that NOAA apparently has a crack team of specialists whose sole job is constantly to change web addresses to keep us off balance (conspiracy theorists take note). If one of these links has expired, they've done it again. Tired of it? A list of your congressional representatives can be found here. (You might also be kind enough to let us know, too, after you send them a scathing denunciation.)
