Subject:Corrected: Soliciting Comments until July 15, 2014, on

††††††††† the Experimental User Defined Area Forecast Point-and-

††††††††† Click Web Application


Corrected to change date in subject line July 15, 2014.


Effective Monday, July 15, 2013, at noon EDT, 1400 Coordinated

Universal Time (UTC), and continuing until July 15, 2014, the NWS

is accepting comments on the User Defined Area Forecast (UDAF)

point-and-click web application for the conterminous United

States (CONUS) only.


The UDAF is an Internet-accessible application allowing direct

interaction with the full resolution (2.5km horizontal grid

spacing) NWS netCDF forecast database to obtain forecast

information within a user specified geographic area. 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. This

database is populated by NWS meteorologists at local Weather

Forecast Offices (WFOs) responsible for that user-defined polygon



Output is presented in the same format as the point-and-click

forecast, but based on an average value of the specified area.

Additionally, the application creates a table with maximum and

minimum values, along with statistics about the size and

elevation range of the selected area. The area itself is

displayed graphically to ensure it matches the userís identified

zone of interest.
