So, the NHC has begun its use of the 5-day graphical Tropical Weather Outlook (TWO). This comes after a 4-year test of their 5 day skills in forecasting tropical cyclogenesis.
The 5-day chart will include everyone's favorite Crayola ovals, now expanded to include 5 days of potential formation area. The correspondingly colored “X” will be the location of the disturbance at the time of the TWO's issuance. An arrow will be used whenever the X (x marks the spot) is located outside of the potential formation area (our colorful ovals). The same colors will be used (yellow = low, orange = medium, red =high).
More explanation (and a link to the feedback survey) is here at the NHC's blog: NHC Blog
For the 48-hour graphics, it will look similar to the current overlay of clouds, but the 48 hour forecast will have Xs marked with centers of the disturbances, and colored according to the 48-hour outlook. The NHC will also put the corresponding colored percentages and numbers (numbers mark the order of appearance of these disturbances and give the NHC a reference label) next to each colored X.
