Subject: Hurricane Threats and Impacts (HTI) Mosaic Testing on
April 8, 2021 (Backup date: April 22, 2021)
The 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 Thursday, April 8. Thursday, April 22 has been
designated as the backup test date in the event that testing
cannot be conducted on April 8.
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
HTI grids are created by WFOs for their county warning area 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 also can be found on
the WFO Tropical Web Portal page linked below under the Threats
and Impacts tab: https://www.weather.gov/srh/tropical
Periodic software and hardware testing in preparation for
tropical cyclone events will continue during the remainder of

The National Hurricane Conference will take place June 14-17 in
New Orleans, Louisiana. The primary goal of the National Hurricane
Conference is to improve hurricane preparedness, response, recovery,
and mitigation in the US, the Caribbean Basin, and the Pacific.
The conference serves as a national forum for federal, state, and
local officials to exchange ideas, and recommend new policies to
improve emergency management. EMI and FEMA certificate training
courses are offered, as well as workshops and training sessions
on a wide range of topics for hurricane responders.
General session speakers will include many of the nation's top
experts in hurricane-related issues. Radio amateurs involved in
hurricane response are invited. In years past, radio amateurs
who attend the amateur radio related conferences have been able
to do so, free of charge.
The 2021 Atlantic Hurricane Season begins on June 1, and runs
through November 30. The National Hurricane Center (NHC) will
