In worded products, localized weather is generally described by geographic phrases such as "over the mountains" or "near the shore." Forecasters use interactive tools in IFPS to manipulate forecast grids that represent the weather in these localized areas. Recent advances in computing have made it feasible to use finer grid spacing in IFPS, improving the depiction of weather in these areas. IFPS summarizes weather from many gridpoints to create a set of phrases for the general area. It also summarizes weather over forecaster-selected localized regions to create a different set of phrases. The two sets of phrases are merged to create the final worded forecast.
