Next Generation Warning Tool (NGWT)

The Next Generation Warning Tool (NGWT) aims to revolutionize the National Weather Service's watch/warning process through an integrated software system that aligns with operational needs. The project addresses significant shortcomings in current warning applications by creating a user-friendly, responsive tool. Immediate improvements focus on usability and incorporating feedback from field tests. Strategic solutions will optimize flexibility and utility, ensuring that meteorological insights are effectively communicated. A collaborative approach is key, engaging regional representatives in defining requirements and developing the tool through prototyping.

  1. Next Generation Warning Tool(NGWT) Jason Tuell Systems Engineering Center Office of Science and Technology

  2. Overview • Background • Near term solution • Strategic solution • Implementation considerations • Summary

  3. Background • Need to create integrated warning tool • Responsive streamlined software system in sync with WFO forecast, watch/warning process • Minimize training, support resources • Need to address significant shortcomings in WWA application • Provide foundation for future requirements • Allow long fuse warnings to leverage the digital forecast process • Anticipate changes in formats and allow greater geographical specificity

  4. Near term solution • Minimize the pain – make current version of WWA tolerable – more responsive to operations • More than 50% of OB3, OB4 WWA development effort targeted at improving usability • Field engaged in “test driving” OB3, OB4 WWA • OB3 test drive 4 November – OB3 WWA well received by regional representatives • OB4 test drive 18-19 February - OB4 WWA identified as significant improvement • Keep Watch-by-County and VTEC on track

  5. Near term – the pain G G G G

  6. Strategic solution • Objective: Improve watch/warning tools • Optimize utility and flexibility for WFO operations • Keep what works well, re-design what doesn’t • Make software sync with the forecasting process • Anticipate future requirements and concepts of operation • Strategy • Use disciplined software development approach which identifies user needs and design constraints early in the process • Create dedicated, cross functional team to define requirements through use cases • Review governing policies in parallel • Spiral development – build some, test some, field some – used with great success in Rapid Prototype Project

  7. Implementation considerations • Separate meteorological from formatting tools • Meteorological tools will allow forecasters to focus on the what, where and when of warnings • Formatting tools will focus on how content is delivered to customers • Dissemination methods and contents to be flexible to accommodate alternative technologies • XML, GIS, graphics?

  8. Summary • Next Generation Warning Tool commitment made to field to overcome shortcomings in current software • Team approach critical to success of defining and developing tool • Need regional representatives to the requirements definition team • Prototyping the best method to deliver capability that the field wants
