About this data
- Distances are from the center of Harrisburg, 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.

Gusts, tornadoes and hurricanes in Harrisburg
Estimated peak gusts
No day since October 1, 2021 had an estimated peak gust of 58 mph or more at Harrisburg.
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.

NOAA recorded 23 tornadoes whose path came within 10 miles of Harrisburg since 1950; the strongest was rated EF2.
