@georgewells , news agencies are most likely getting their data from the National Hurricane Center, who are in turn getting their wind speed data by flying an airplane into the storm. This website relies on a few standard models to present it's graphics, not actual observations.

@Siff , it is mentioned in the about section. It says the site uses three weather models. i don't see why you feel they need to spell out the things they do not use.
