Subject:   Tropical Cyclone Watch/Warning Product (TCV) 
           Collaboration Testing August 15, 2022

The NWS National Hurricane Center (NHC) and Weather Forecast
Offices (WFOs) in Boston/Norton, Massachusetts, New Orleans,
Louisiana, and Miami, Florida will conduct internal software and
hardware testing of the National Tropical Cyclone Watch/Warning
(TCV) product collaboration process Monday, August 15, 2022.  Test
activities are expected to be conducted each day between 1900 UTC
and 2200 UTC.  Tuesday, August 16, 2022 is the designated backup
day.   

The National TCV product contains a summary of collaborated wind
and/or storm surge watches and warnings, depicted by NWS-defined
geographic zones.  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 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)  

While unlikely, there is a slight chance that the tropical
expressions of uncertainty (i.e., "Tropical Storm Conditions
Likely", "Hurricane Conditions Possible") could unintentionally
appear on weather.gov Point and Click forecast pages temporarily
because this test includes the internal creation of tropical wind
speed probabilities.

The NWS will continue periodic internal tropical software testing
during the remainder of this hurricane season as needed.
