           (TCV) Collaboration Tests

The National Hurricane Center (NHC) and National Weather Service
(NWS) Weather Forecast Offices (WFOs) in the NWS Southern Region and
in the NWS Eastern Region, will commence with internal software and
hardware testing of the national tropical cyclone watch/warning
(TCV) product collaboration process for the Atlantic basin on
Monday, June 3 and continue daily through Thursday, June 6, 2019.

Internal testing will begin at approximately 1400 GMT and terminate
at 1900 GMT daily during scheduled test days.  In the event of
inclement weather, Friday, June 7, 2019 has been reserved to serve
as backup date for any portion of testing that was delayed.

Internal TCV test products are not intended to be released
externally through NWS dissemination and communication systems.  The
text products affected by collaboration testing are the National
Tropical Cyclone Watch/Warning (TCV) products issued under the
following AWIPS Product Identifiers (PIL) and World Meteorological
Organization (WMO) Identifiers (ID):

TCV Product                    AWIPS PIL   WMO ID
------------                   ---------   -------
Preliminary TCV                PTCAT/1-5/  WTNT/81-85/ KNHC
National TCV                   TCVAT/1-5/  WTNT/81-85/ KNHC

In addition, the following National Digital Forecast Database (NDFD)
elements will be created for this test:
     - tropical cyclone wind probabilities (incremental and
          cumulative) for 34 kt, 50 kt, and 64 kt
     - hazard grid (including tropical storm, hurricane, and
          storm surge hazards)

Periodic NHC and WFO internal software and hardware testing will
continue during the remainder of 2019. The national TCV product for
the Atlantic basin will contain a summary of NHC/WFO collaborated
wind and/or storm surge watches and warnings, depicted by
NWS-defined geographic zones.
