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 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.
