Effective May 15, 2011, the following changes to tropical

to the product issuance criteria, AWIPS IDs, or WMO headings,
users who parse portions of these products may need to make
changes in their software applications.
1. Mass News Disseminator(MND)header block changes:
a) Blank line will be added between the MND header block and
the AWIPS header information for text products issued for
the Atlantic and Eastern Pacific basins. This format is
already used by the Central Pacific Hurricane Center and
the Weather Forecast Office Guam. An example and a
complete list of affected products with WMO headers and
AWIPS IDs can be found at:
http://www.nhc.noaa.gov/2011_mnd.shtml

the Weather Forecast Office (WFO) Guam .

HPC will adopt the format of the Product Type Line already
used by NHC, CPHC and WFO Guam.
The standardized format for the Product Type Line is:
(TROPICAL CYCLONE TYPE)(NAME) ADVISORY NUMBER (NN)
In addition, the TROPICAL CYCLONE TYPE in the products
issued by NHC, CPHC, and WFO Guam, and in the TCP
products issued by HPC, will account for a broader range
of tropical cyclone types.

used effective May 15, 2011 is:
TROPICAL DEPRESSION
TROPICAL STORM
HURRICANE
TYPHOON

section is included, and in the Tropical Cyclone Surface Wind

the abbreviation of kilometers per hour will change from
KM/HR to KM/H. This change also affects the TCP issued by
WFO Guam.
