With the migration of the current AWIPS into a new Service Oriented Architecture, the National Weather Service will have a modern and robust foundation for meteorological and hydrological software. NAWIPS is the other suite of meteorological and hydrological software used by the National Weather Service. It is used extensively at National Centers, River Forecast Centers and many Weather Forecast offices. Migrating NAWIPS in to the new SOA will help create a seamless weather enterprise.

The objective of this migration is to support both AWIPS and NAWIPS applications within the same architectural framework. It is not intended to replace one set of applications with the other. Integrating the NAWIPS applications into the same architectural framework provides the foundation for the introduction of new enterprise wide capabilities, e.g., integrated graphical collaboration.

This paper defines our NAWIPS migration plans and schedule, and describes the challenges and outcomes of the planned migration. This paper will also describe some of the attendant benefits of having both NAWIPS and AWIPS applications within the same architectural framework.
