         Experimental Five-Day Graphical Tropical Weather

         Outlook through November 30, 2014


Effective July 1 and continuing through November 30, 2014, the

National Weather service (NWS) is seeking user feedback on an

experimental Five-Day Graphical Tropical Weather Outlook issued

by the National Hurricane Center (NHC).


The Five-Day Graphical Tropical Weather Outlook (XGTWO) is a

visual companion to the five-day (120-hour) forecasts and

discussion currently appearing within the Tropical Weather

Outlook (TWO) text product, and will be produced four times daily

by the NHC for the Atlantic and east Pacific basins.  The XGTWO

is a web-based set of graphics that identify the locations of

current areas of disturbed weather and the areas where these

disturbances could develop into tropical or subtropical cyclones.

The current disturbance locations are shown with Xs and the

potential formation areas are shown with shaded hatches.  The

areas are color-coded based upon the forecast likelihood of

tropical cyclone formation in the next five days, with yellow

indicating a less than 30 percent chance, orange indicating a

chance of 30-50 percent, and red indicating a formation

likelihood of greater than 50 percent.


An overview XGTWO image shows all disturbances mentioned in the

text TWO.  When a user moves the computer mouse pointer over a

disturbance in the graphic, the associated text for that

disturbance pops up.  Clicking on a disturbance will display a

version of the graphic showing only that particular disturbance.

Each of the single-disturbance graphics displays the quantitative

genesis probability, given in 10 percent increments, and a

disturbance number (i.e., Disturbance 1, Disturbance 2), with the

text for each numbered disturbance given beneath the graphic.


The graphic can be found on NHCs website at:
