Pretty much all hell is breaking loose and sliding downhill throughout the region today. The best place to get an overview of what's going wrong in metro Seattle is at the Regional Public Information Network site, a clearinghouse for official news – an Emergency Broadcast System of the Web. The Seattle Times and the Seattle Post-Intelligencer both have stories posted that are being updated, and the Times has a Google Maps mash-up of flood reports from readers. The Oregonian uses a blog tool to post breaking news, and their OregonLive home page is a good place to see the big picture of mayhem in Oregon. National Weather Service warnings and forecasts, including river-flow data: Seattle and Western Washington, Portland and northwestern Oregon.
