Subject: Hurricane Threats and Impacts (HTI) Mosaic Testing on
April 25, 2024
Weather Forecast Offices (WFOs) in the National Weather Service (NWS)
Southern and Eastern Regions will commence with Hurricane Threats and
Impacts (HTI) threat grid mosaic testing on Thursday, April 25.
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,
Storm
Surge Threat, Flooding Rain Threat, and Tornado Threat at each
participating WFO. Those grids are stitched together into
storm-scale HTI
graphics. The HTI Mosaic graphics are available in Keyhole Markup
Language (KML) format on the following webpage:
https://www.weather.gov/hti
The mosaics are also available through the National Digital Forecast
Database and on web pages hosted by the Weather Forecast Offices
(WFOs)
affected by the tropical cyclone. These webpages use the following
URL
format, where “wfo” should be replaced with the 3 digit
identifier for the
WFO of interest:
NWS Eastern Region WFOs:
https://www.weather.gov/wfo/tropical#hti
NWS Southern Region WFOs:
https://www.weather.gov/srh/tropical?office=wfo#hti
More details on HTI can be found in the Product Description Document:

Periodic software and hardware testing in preparation for tropical
cyclone
events will continue during the remainder of 2024.
