National Weather Service Weather Forecast Offices (WFOs) that issue tropical storm, hurricane, and/or storm surge watches and warnings provide Hurricane Threats and Impacts graphics that convey a reasonable worst-case forecast that incorporates uncertainty to best tell our users what conditions to prepare for during a tropical cyclone event.  These graphics are available in KML format using the links provided below.

These graphics are also available through the National Digital Forecast Database and on interactive web pages hosted by the WFOs affected by the tropical cyclone.  These webpages use the following url format, where “wfo” should be replaced with the 3 letter identifier for the WFO of interest (i.e., WFO Philadelphia = “phl”):
