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

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
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?
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
