Subject: Tropical Cyclone Watch/Warning Product (TCV)
Collaboration Testing April 25-29, 2022
The National Weather Services (NWS), National Hurricane Center
(NHC), Weather Prediction Center (WPC), Ocean Prediction Center
(OPC), and Weather Forecast Offices (WFOs) in the NWS Eastern and
Southern Regions will proceed with internal software and hardware
testing of the National Tropical Cyclone Watch/Warning (TCV)
product collaboration process April 25-28, 2022. Test activities
are expected to be conducted each day between 1600 UTC and 1900
UTC. Friday, April 29, 2022 is a 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.
