Enhanced Service, allowing user to select area for which forecast information is derived from the point-and-click data base.The User Defined Area Forecast (UDAF) is an Internet-accessible application which allows direct interaction with the full resolution (2.5km horizontal grid spacing) NWS netCDF forecast data base to obtain forecast information within a geographic area specified by the user. The interface allows an individual to define geographical boundaries in both area and elevation, and submit those values to retrieve a forecast directly from the digital forecast data base populated by NWS meteorologists at local weather forecast offices (WFOs) responsible for that user-defined polygon domain. Output is presented in the same format as the point-and-click forecast, but based on an average value of the area specified. Additionally, a table with maximum and minimum values is created, along with statistics about the size and elevation range of the selected area. The area itself is displayed graphically to ensure the area from which the data is derived matches the user's identified zone of interest. A future upgrade will incorporate affected population within the table, by querying the US census data base.
