On April 19th, 2017, all Western Region (WR) NWS Weather Forecaast Offices (WFOs), and Center Weather Service Units (CWSUs)  migrated to a new layout on the front page of their web home pages. This change is in response to a required web infrastructure consolidation. The change will provide office-to-office consistency because the layout of the home page will be set across the Region. But where will everything be on this new site? We try to answer these and any other questions you may have about our new site here.
