Subject: Elimination of the Tropical Cyclone Position Estimate

         Product with the information provided in the

         Tropical Cyclone Update Product Effective May 15, 2013     

         

Effective May 15, 2013, the Tropical Cyclone Position Estimate

(TCE) product issued by the National Hurricane Center (NHC) and

Central Pacific Hurricane Center (CPHC) will be terminated. The

information previously provided in the TCE will be provided in

the Tropical Cyclone Update (TCU) product.

 

Effective June 26, 2013, the TCE product issued by WFO Guam will

be terminated. The information previously provided in the TCE

will be provided in a new TCU product issued by WFO Guam.

 

The TCE provides information regarding the center location of a

tropical cyclone when it nears the coast and the center can be

easily tracked with land-based radar. In recent years, the TCU

was modified and now can include a summary block that conveys not

only the storm's center location but also other key parameters. 

The TCU's summary block now contains all of the information

previously conveyed in the TCE, so there is no longer a need for

the TCE. In those situations where a TCE would have been issued,

the NWS will issue a TCU instead. Substituting the TCU for the

TCE provides the same continuous flow of information with the

advantage of a fixed, easily decoded format within a single

product.

 

The WMO headers and AWIPS IDs that will be discontinued are as

follows:

 

Basin                      WMO Header         AWIPS ID

Atlantic                   WTNT/51-55/ KNHC   TCEAT/1-5/

Eastern Pacific            WTPZ/51-55/ KNHC   TCEEP/1-5/

Central Pacific            WTPA/51-55/ KHFO   TCECP/1-5/

Western North Pacific      WTPQ/51-55/ PGUM   TCEPQ/1-5/

 

The WMO headers and AWIPS IDs for the TCU products issued by NHC

and CPHC will remain unchanged and are as follows: 

 

Basin                      WMO Header         AWIPS ID

Atlantic                   WTNT/61-65/ KNHC   TCUAT/1-5/

Eastern Pacific            WTPZ/61-55/ KNHC   TCUEP/1-5/

Central Pacific            WTPA/61-55/ KHFO   TCUCP/1-5/

 

Currently WFO Guam does not issue TCU products but effective June

26, 2013, it will have the capability.  The following new WMO

Headers and AWIPS IDs will be used by WFO Guam when issuing a TCU

product: 

 

Basin                      WMO Header         AWIPS ID

Western North Pacific      WTPQ/61-65/ PGUM   TCUPQ/1-5/

 

Partners and users will need to update their system(s) to receive

TCU products from WFO Guam.
