           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 on 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.
