The NWS National Hurricane Center (NHC), Ocean Prediction Center

7, is the designated backup week.

Internal testing will begin at approximately 1600 GMT and
terminate at 1900 GMT 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

In addition, the following National Digital Forecast Database
