Subject:   Soliciting Comments for Experimental Wind Speed
           Probabilities-Based Tropical Cyclone Danger Graphic
           through November 30, 2012

The NWS Tropical Analysis and Forecast Branch (TAFB) is seeking
user feedback on its experimental wind speed probabilities-based
tropical cyclone danger graphic through November 30, 2012.

TAFB is providing an experimental Tropical Cyclone Danger Area
Graphic based on the 34-kt wind speed probabilities through
72 hours. The graphic is based on the latest tropical cyclone
advisory for an active tropical cyclone.  The graphic outlines
avoidance areas using the 10% and 50% 34-kt wind speed
probability contours from the latest tropical cyclone advisory
issuances for both the Atlantic and East Pacific basins.  The
current Tropical Cyclone Danger Area graphic uses the mariners
1-2-3 rule to outline avoidance areas for active tropical
cyclones.  Feedback from users indicated that the 1-2-3
methodology has led to "over-warned" large avoidance areas.

In the event there are no active tropical cyclones in either
basin, the graphic will be blank with the following wording THERE
IS NO TROPICAL CYCLONE ACTIVITY IN THE ATLANTIC or THERE IS NO
TROPICAL CYCLONE ACTIVITY IN THE EAST PACIFIC.

These experimental tropical cyclone danger area graphics are
available four times daily at 0400, 1000, 1600, and 2200
Universal Coordinated Time (UTC) on the National Hurricane Center
(NHC) website at:

     http://www.nhc.noaa.gov/marine/
