About this opportunity
The National Oceanic and Atmospheric Administration (NOAA) has published a Special Notice announcing a vendor engagement session for the Common Analytic and Support System (CASS) project serving the National Weather Service's Tsunami Warning Centers. The session is scheduled for December 18, 2025, from 2:00 p.m. to 3:00 p.m. Eastern Time and will be conducted virtually via Google Meet. This Special Notice is being issued in advance of a formal solicitation to allow interested vendors an opportunity to learn about the project requirements and ask questions directly with government representatives. The engagement session represents NOAA's Western Acquisition Division effort to facilitate early information exchange between government and industry stakeholders.
The primary objective of this engagement session is to provide prospective contractors with a comprehensive overview of the CASS requirement, acquisition strategies, and an opportunity to submit pre-reviewed questions and comments. Contractors interested in participating must pre-register for the event, with registration details available through the formal announcement; those unable to attend will receive copies of the briefing materials. Key requirements include the development of a comprehensive software system that incorporates original Common Analytic System (CAS) code and enables service backup and synchronization between tsunami warning centers in Palmer, Alaska and Honolulu, Hawaii. Contractor personnel must be U.S. citizens with appropriate security clearances, as the system will operate under 24/7 high-impact FISMA security constraints with a one-year performance period and potential one-year extension. All developed materials and source code will be owned exclusively by the government, with strict intellectual property and data rights provisions enforced.

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.
