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.
