The NWS National Hurricane Center (NHC), Weather Prediction
Center (WPC), Ocean Prediction Center (OPC), and Weather Forecast
Offices (WFOs) in Eastern Region and Southern Region will perform
internal testing of the National Tropical Cyclone Watch/Warning
(TCV) product collaboration process for the Atlantic Basin daily
from Monday, May 15, 2023 through Thursday, May 18, 2023. Friday,
May 19 is a designated backup day.

Internal testing will begin at approximately 12:00 PM EDT and
terminate at 3:00 PM EDT daily during the scheduled test days.

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
------------                   ---------   -------

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)


The NWS will continue periodic internal tropical software testing
