VENDOR ENGAGEMENT SESSION ANNOUNCEMENT: COMMON ANALYTIC AND SUPPORT SYSTEM (CASS) FOR THE NOAA NATIONAL WEATHER SERVICE (NWS) TSUNAMI WARNING CENTERS (TWCS)

CASS Vendor Engagement Session Announcement:

18 December 2025, 1400-1500 Eastern Time (ET). 

I. SUMMARY

NOAA’s National Weather Service (NWS) operates two U.S. Tsunami Warning Centers (TWC), National TWC (NTWC) in Palmer, AK and the Pacific TWC (PTWC) in Honolulu, HI. The TWCs require a Common Analytic and Support System (CASS) to provide comprehensive and consistent forecast and alerting guidance in support of joint TWC Operations. CASS must incorporate originally-developed code from the first version of this requirement, the Common Analytic System (CAS), the tsunami modeling component of the CASS platform.

NOAA's Western Acquisition Division will host a virtual vendor engagement session to provide interested parties with an overview of the CASS requirement for the NWS TWCs. This virtual session is being held to promote an early exchange of information and provide an opportunity for both the Government and Industry to gather more information prior to the release of a formal solicitation.

At this session, the Government will provide an overview of the CASS requirement and address pre-submitted questions and comments regarding the technical requirement and acquisition strategies. There will also be time allotted for a live Q&A session. 

The session will only be open to vendors who pre-register for the event. Vendors who are not able to attend the event may still obtain a copy of the presentation material. Any briefing slides will be sent out to all who register.
