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.
