Yesterday, FEMA illustrated its G eo-Targeted Alerting System (GTAS) project, a prototype application of plume modeling and high resolution weather models that may eventually be used for alerting the public.

The application is essentially a map-based notification interface, however, it is connected to some very useful data. First, it receives high-resolution weather data and modeling feeds from the National Weather Service. These feeds allow emergency managers to visualize areas in the path of dangerous weather (currently or forecasted) and to select these areas for the issuance of highly targeted public emergency notifications. Further, the app provides built-in collaboration tools so emergency managers can can work with outside experts to clarify the information being presented.
