Subject:   Western Region Web Changes: New Layout, and Secure
   Communications effective April 18, 2017

On or shortly after April 18, 2017, all Western Region (WR) NWS
Weather Forecast Offices (WFOs), and Center Weather Service
Units (CWSUs) will migrate 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.

In addition, per Office of Management and Budget (OMB) directive
M-15-13, all publicly accessible federal websites and services,
namely, and WR River Forecast Centers (RFCs).
will only provide service through a secure connection (https).

The OMB directive can be found at:
