Coastal NWS Weather Offices now produce a suite of graphics that serves to complement the corresponding Hurricane Local Statement (HLS) text product. They are hosted on an NWS web site and provide an internet-based decision-support service consisting of at least four graphics: high wind impacts, coastal flooding impacts, inland flooding impacts, and tornado impacts. For the Atlantic/Gulf Hurricane Season, the graphics will be generated and posted by the 23 coastal NWS Offices whenever Tropical Cyclone Watches and/or Warnings are in effect for their area.

The Interactive Hurricane Local Statement for NWS Jacksonville is an interactive Text Reader for the segmented Hurricane Local Statement (HLS) text product. By segmenting the HLS product into corresponding geographic areas of concern, it is designed to make it easier to extract the desired local information. This page has a suite of BLANK graphic backgrounds in 5 tabs that depict Wind, Coastal Flood, Inland Flood Tornadoes and Marine areas overlaid with the segmented HLS Text product. These tabs are active whenever tropical cyclone watches/warnings are in effect locally, and refreshed with each issuance of the HLS by your local forecast office.

Hurricane Threats and Impacts: The purpose of Hurricane Threats and Impacts (HTI) is to facilitate the proportionate implementation of your emergency action plan based on descriptions of potential impact unique to your area. The intent is to invoke a measured response that is reasonable and responsible by considering the composite of plausible outcomes in context of the event at hand. These HTI images are designed to complement the Interactive HLS and provide a graphical .png image, KML or google map overview of the potential impacts for threat assessment. The assessment scheme takes into account the forecast magnitude of the hazard, along with the associated uncertainty of the forecast. They provide an "at-a-glance" summary of potential impacts that have the reasonable chance to occur.
