The manual Dvorak fixes issued by SAB for tropical disturbances and tropical cyclones in the Eastern and Southern Hemispheres, such as those found at: http://www.ssd.noaa.gov/PS/TROP/ are being considered for retirement. Specific basins affected are the West Pacific, North Indian, South Indian, South Pacific, South Atlantic and Mediterranean Sea. The ADT based on forecasts issued by RSMCs in the Eastern and Southern Hemisphere is also being considered for retirement. Specifically, ADT output found on http://www.ssd.noaa.gov/PS/TROP/adt.html under the headers for New Delhi, Tokyo, La Reunion, Australia and Nadi would no longer be produced. All other ADT output would continue to be available to users, including ADT output based on JTWC forecasts in the affected areas. Interested parties may address their comments and concerns regarding this proposed retirement to Michael.Turk@noaa.gov through November 18, 2016.

|Text bulletins disseminated by 0100Z, 0700Z, 1300Z, and 1900Z describing the position and intensity estimates for tropical disturbances and tropical cyclones in the Eastern and Southern Hemispheres.||
Subjective position estimates of tropical disturbances and cyclones across the globe using a variety of microwave sensors.
The Total Precipitable Water (TPW) is a unified, meteorologically significant TPW field blending AMSU, SSM/I and GPS TPW together, for non-gap global coverage.

|The eTRaP is a simple ensemble that allows for the generation of probabilistic forecasts of rainfall in addition to deterministic rainfall totals.|
|MTCSWA combines information from several data sources to create a mid-level wind analysis which is then adjusted to the surface. Eight products are displayed, most notably an inner core scale surface wind analysis.||
The Tropical Cyclone Formation Probability Product provides an estimate of the probability of tropical cyclone formation within the next 24 hours in 1 by 1 degree latitude/longitude areas from 45S to 45N and 0 to 360E.|
|The ADT provides an automated, objectively-derived estimate of the tropical cyclone location and intensity using the latest official forecast bulletins from the Joint Typhoon Warning Center (JTWC) and from Regional Specialized Meteorological Centers (RSMC), such as the National Hurricane Center (NHC) and the Central Pacific Hurricane Center (CPHC).|
