1. Overview
Note: This product has become operational beginning with the 2009 hurricane season.
The Graphical Tropical Weather Outlook (GTWO) is a product issued by the National Hurricane Center
(NHC) that will become operational at the start of the 2009 hurricane season. A GTWO is issued for both the Atlantic and
eastern North Pacific Ocean basins. The GTWO products began as experimental products during the 2007 hurricane season and
are intended to be a visual companion product to the text Tropical Weather Outlook (TWO). The GTWOs are issued four times
daily for each basin and will be available shortly after the issuance of the text TWO.
