About this data
- Distances are from the center of Duluth, not from any one property. Look up a street address below for a single building.
- Reports come from trained spotters and the public, so they cluster near towns and roads.
- No report does not mean no hail. Hail can fall where no one is there to report it.
- This is not a damage or insurance assessment.

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.
