Subject: Extending Comment Period for Experimental Tropical

Cyclone Impacts Graphics through November 30, 2013


Effective June 1, 2013 and continuing through November 30, 2013,

NWS is seeking user feedback on experimental Tropical Cyclone

Impacts Graphics.


The Tropical Cyclone Impact Graphics are an internet-based

product suite consisting of four hazard graphics: wind, tornado,

coastal flood, and inland flood. Each graphic is based on the

most recent threat assessment as centered on a particular

geographic area of interest and is presented in terms of

potential impact while using associated descriptions unique to

that area. The graphics take into account the forecast magnitude

of the hazard, along with the associated uncertainty of the



These experimental products will be generated by participating

coastal Weather Forecast Offices (WFOs) when the National

Hurricane Center (NHC) issues a tropical cyclone watch and/or

warning for a WFOs area of forecast and warning responsibility.

There are no changes in the format of the graphics for the 2013

hurricane season. The graphics, along with a description and

static examples, will be posted online at:


The default graphic will be in KML format displayed on an

interactive Google Earth background map. A .png file will also

be available. NetCDF and KML files for the four impact graphics
