When we obtain reports from across the region - whether from spotters, the general public, or solicited information from people like PennDOT or Emergency Personnel - we quality-check the data. We then try to issue Public Information Statements that summarize this information. Latest 24-hr Snowfall Report Map

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: https://www.weather.gov/media/srh/tropical/PDD_HTI.pdf
Periodic software and hardware testing in preparation for tropical cyclone events will continue during the remainder of 2024.
