Subject: Hurricane Threats and Impacts (HTI) Mosaic Testing on
April 24, 2025

The National Weather Service (NWS) Weather Forecast Offices (WFOs)
in Honolulu, Hawaii, San Juan, Puerto Rico, and all WFOs in the
contiguous United States that can issue tropical storm and
hurricane hazards will commence with Hurricane Threats and Impacts
(HTI) threat grid mosaic testing on Thursday, April 24, 2025.
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,
Flooding Rain Threat, Tornado Threat, and Storm Surge Threat
(where applicable) 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 tropical cyclones. These webpages
include WFO Tropical Webpages and Graphical Hazardous Weather
Outlook (GHWO) Webpages.

GHWO Webpages use the following URL format, where XXX should be
replaced with the 3-letter identifier for the WFO of interest
(note that WFO Honolulu does not have a GHWO webpage):
https://www.weather.gov/erh/ghwo?wfo=XXX

WFO 3-letter identifiers and the respective NWS Region that each
WFO belongs to is listed at the following page:
https://www.weather.gov/pimar/CWAbyWFO

NWS Eastern, Southern, and Western Region WFO Tropical Webpages
use the following URL format, where XXX should be replaced with
the 3 letter identifier for the WFO of interest:

NWS Eastern Region WFOs:
https://www.weather.gov/XXX/tropical#hti

NWS Southern Region and Western Region WFOs:
https://www.weather.gov/srh/tropical?office=XXX#hti

Periodic software and hardware testing in preparation for tropical
cyclone events will continue during the remainder of 2025.
