English: Wind history of Hurricane Hermine from National Hurricane Center Advisories 1 (August 28) through 38 (September 6), although there was no history of tropical storm force winds until Advisory 13 on August 31. The storm still had tropical storm force winds at the time of the final advisory, Advisory 38, on September 6. It was downgraded to a post-tropical cyclone on September 3 (Advisory 25). Thus this graphic is neither a complete wind history of the storm across its lifespan nor solely a wind history of the storm while it was a tropical cyclone.
According to the NHC, the wind history graphic "shows how the size of the storm has changed, and the areas potentially affected so far by sustained winds of tropical storm force (in orange) and hurricane force (in red). The display is based on the wind radii contained in the set of Forecast/Advisories indicated at the top of the figure. Users are reminded that the Forecast/Advisory wind radii represent the maximum possible extent of a given wind speed within particular quadrants around the tropical cyclone. As a result, not all locations falling within the orange or red swaths will have experienced sustained tropical storm or hurricane force winds, respectively."
