The NWS is soliciting comments on the addition of U.S. Inland Watches/Warnings to Tropical Cyclone Track and Error Cone Graphic:
https://www.surveymonkey.com/r/ExpInlandWWonConeGraphics_2024

Beginning on or around August 15, 2024, NHC will begin issuing an experimental version of the cone graphic that includes inland tropical storm and hurricane watches and warnings in effect for the continental United States. Recommendations from social science research suggest that the addition of inland watches and warnings to the cone graphic will help communicate inland wind risk during tropical cyclone events while not overcomplicating the current version of the graphic with too many data layers. There will be opportunities to provide feedback during the product’s experimental phase. Owing to the experimental nature of the graphic, it may not be available as soon as the current operational cone graphic due to the time needed to compile complete inland watch and warning information, but should generally be available within 30 minutes of the advisory release. The current operational cone graphic will continue to be available, and there will be no changes with respect to how coastal watches and warnings are displayed on that graphic. The new experimental graphic will be available on the NHC website for both full and intermediate advisories.

The NWS will evaluate the comments received and will determine any additional need for changes based on public feedback. Please provide feedback through the NWS survey at: https://www.surveymonkey.com/r/ExpInlandWWonConeGraphics_2024
