Subject:  Discontinuation of the Text Satellite Tropical
          Disturbance Rainfall Estimates Product for the 
          Caribbean, Central America and the Gulf of Mexico
          Effective July 30, 2013
 
Effective Tuesday July 30, 2013, at 200 pm Eastern Daylight Time
(EDT), 1800 Coordinated Universal Time (UTC), the Tropical
Analysis and Forecast Branch (TAFB) of the National Hurricane
Center (NHC) will stop issuing the current operational version of
the text Satellite Tropical Disturbance Rainfall Estimates
product for the Caribbean, Central America and the Gulf of
Mexico.
 
The National Centers for Environmental Prediction will be
transitioning to the WCOSS super computer on July 30, 2013. NHC
management has decided to further develop the experimental
satellite rainfall program so it can migrate to WCOSS for
operational implementation.
 
Users are directed to the Experimental Satellite Rainfall 
Product on the National Hurricane Center website at

Rainfall 80W to 120W          
 
The effective date of this change is sooner than specified by NWS
Policy (NWS Instruction 10-1805).  The shorter advance lead time
was necessitated by uncertainty in timing of migration to a new
supercomputer, and approved because the current users will not
have to make any adjustments to accommodate the change.

of the text Satellite Tropical Disturbance Rainfall Estimates
Product for the Caribbean, Central America and the Gulf of Mexico
