Subject:  Amended: Soliciting Comments through December 31, 2013, on an

          Experimental National Digital Forecast Database Map



Amended to extend comment open period thru December 31, 2013


NWS is accepting comments through December 31, 2013, on an

experimental National Digital Forecast Database (NDFD) map viewer

online at:


Partners and users may view NDFD information for both the CONUS

(experimental 2.5 km grid resolution) and OCONUS (current

operational grid resolution) by using the drop down menu.


This proposed map viewer is in response to numerous comments and

suggestions for more efficient and effective data display and

interaction.  The proposed map viewer takes advantage of the

capabilities of modern web browsers and enables users to

interactively zoom and roam NDFD forecast grids.


Static images of NDFD grids at current operational resolution

will remain available at:


NWS partners and users are encouraged to provide feedback via a

comment link at the top of the experimental NDFD map viewer or
