Subject:   Hurricane Threats and Impacts (HTI) Mosaic Testing on
           April 21, 2020 (backup date: April 22)

The National Weather Service (NWS) Weather Forecast Office (WFO)
in Honolulu and WFOs in the NWS Southern Region and in the NWS
Eastern Region will commence with Hurricane Threats and Impacts
(HTI) threat grid mosaic testing on Tuesday, April 21 (backup
date: April 22).

Testing will begin at approximately 1500 UTC.  Test activities
will take approximately 1 hour.  However, NWS dissemination
systems may take up to an hour and a half to purge all test
data.  All test data is expected to be cleared by 1730 UTC.

For the test, HTI grids will be created for Hurricane Wind
Threat, Hurricane Storm Surge Threat, Hurricane Flooding Rain
Threat, and Hurricane Tornado Threat.  These grids are sent to
the National Digital Forecast Database (NDFD) and can be seen on
the NDFD web viewer at:

https://digital.weather.gov

The Product Description Document for these threat grids can be
found here:

https://www.weather.gov/media/srh/tropical/PDD_HTI.pdf

HTI grids are created by WFOs for their county warning areas and
mosaicked together to form a more geographically consistent
depiction of the threat posed by hurricane hazards.  The HTI
mosaics can be found in kml format at:

https://weather.gov/hti

When populated HTI grids are posted, they can also be found on
the WFO Tropical Web Portal Page linked below under the "Threats
and Impacts" tab:
