The WES-2 Bridge is the AWIPS-2 version of the Weather Event Simulator. It allows AWIPS-2 to work with archived data sets to conduct case reviews and displaced real-time simulations.


Current Status


WES-2 Bridge has been upgraded to Version 17.1.1, compatible with AWIPS Build 17.1.1.

WES-2 Bridge has been installed at the majority of NWS Field Offices, and WDTD continues to provide support to each office. Build 17.1.1 supports the FY18 Radar and Applications Course (RAC).

Build 17.1.1 is backwards compatible for Processed data archived from Build 14.3.1 to the present. For addtional information about this build, please see our release notes.

WDTD is currently working on another upgrade for WES-2 Bridge for AWIPS 17.2.1 to be compatible with the RedHat 7 operating system.

Known Issues

Note: A more complete list of issues is located on our Support Page.

Connectivity Preferences Window

When users first log into the WES-2 Bridge workstation, a connectivity preferences window often appears. This is actually an AWIPS-2 issue and not a WES-2 Bridge issue. When AWIPS-2 is installed, AlertViz tries to connect to an EDEX server (either the default server or the last one the user connected to). If the server isn't running, then this window appears. The best option is to ignore this GUI and close it out. Some sites have included starting EDEX_00 in their system startup scripts, but if for some reason EDEX_00 can't start (which can be caused by numerous issues), the workstation likely will not start properly. In addition, since the GUI remembers the last EDEX server the user connected to, simply starting only EDEX_00 may not be good enough to completely prevent this window from appearing.


Using Localizations

Part of the customization process of WES-2 Bridge involves transferring localization files from the operational AWIPS to the WES-2 Bridge workstation. Several offices have transferred the entire localization include BASE files from the operational AWIPS to WES-2 Bridge; numerous AWIPS-related issues have resulted including the inability to process certain data types and issues with WarnGen. We recommend only transferring configured, site, and user directories from the operational AWIPS to WES-2 Bridge.
