Subject: Change to the Tropical Weather Outlook Text
         Products Effective May 15, 2012
Effective May 15, 2012, the following change will occur in the  
Tropical Weather Outlook (TWO) text products to facilitate 
broadcast of the TWO on the NOAA Weather Radio network. While
 there are no changes to the product issuance criteria, AWIPS 
product identifiers, or WMO headers, users who parse portions 
of these products may need to make changes in their software 
applications. These changes also apply to the Special 
TWO text products.
TWO products often contain references to additional AWIPS product 
identifiers and WMO headers, in the body of the product, advising 
users to look for additional information on systems mentioned in 
products issued by other NWS offices or the meteorological services 
of other nations.   
Through 2011, any additional AWIPS product identifiers and WMO 
headers referenced in the body of the TWO were provided above 
the double ampersand (&&) symbols.
Effective on May 15, 2012, any AWIPS product identifiers and 
WMO headers referenced in the body of the TWO will be provided 
below the double ampersand (&&) symbols.
Examples of the new formats for the TWO are provided online at:
