Effective 800 AM EDT August 1 and continuing through November 30, 2013, the NWS is seeking user feedback on an experimental
Extended Tropical Weather Outlook (TWO) issued by the National Hurricane Center (NHC).
On an experimental basis the TWO text product produced by the NHC for the Atlantic and East Pacific basins will include
probabilistic information, in 10-percent increments, about a system’s potential for developing into a tropical cyclone in the
next 120 hours. Currently, the TWO only provides genesis potential out to 48 hours. The extended forecast and discussion
will be embedded within the current TWO text product on a disturbance-by-disturbance basis. Each product will include a
prominent statement that the 120-hr genesis forecasts are experimental.
The text TWO can be found on the web at:
The WMO headers and AWIPS Identifiers (AI) for the text TWO are:
