Estimates: the highest gust of each storm day in NOAA’s hourly 2.5 km wind analysis (URMA), which fills in between weather stations. Analyses like this smooth out short thunderstorm gusts, so they are best for widespread wind (hurricanes, winter storms, high wind days); for thunderstorm wind, NOAA’s wind reports are the better record. Not a measurement at any building.
