Summary

Description
English: Chart showing diameters of hurricanes reaching landfall in the Gulf Coast of the United States, as a function of time
  • Data source: Dance, Scott; Ducroquet, Simon; Muyskens, John. (September 26, 2024). "See how Helene dwarfs other hurricanes that have hit the Gulf Coast". The Washington Post.
  • Washington Post article explains: "A storm’s size is different from its strength, which is based on the maximum sustained wind speeds at its center. While intense storms like Helene, currently a Category 4 storm, often grow as they strengthen, many past storms that were far stronger than Helene were not nearly as large. ... When a storm is so large, it means more people are exposed to its hazards, which extend hundreds of miles away from the point of landfall."
  • Source explains: "In some cases, tropical storm force winds extend significantly farther on the eastern side of the storm than on the western side. The statistics are calculated by averaging the radius of tropical-storm force winds in four directions from the center of the storm. The average is then doubled to represent the width of the storm. . . . . . Sources: National Hurricane Center; analysis by Phil Klotzbach, Ph.D. (Colorado State University)".
  • Technical note: most SVG code was automatically generated by the "Scatter plots" spreadsheet linked at User:RCraig09/Excel to XML for SVG. Additions and adjustments were made in a text editor.
  • Trendline matches that generated separately in Microsoft Excel.
  • Aside: the symbols in this chart are based on the flag warming for hurricanes: Flag signals (File:Hurricane Warning Flags (U.S).svg)
