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.
