Marble Rock, the town this property stands in, in 36 storm reports between 1996 and 2025: 24 hail, 11 thunderstorm wind, 1 tornado.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office

This tornado formed just north of Marble Rock and moved rapidly to the northeast before dissipating west of Charles City. An NWS survey team determined this tornado to have an EF1 rating. The tornado caused damage to homes, farm buildings and metal grain bins along with taking down power poles, power lines and trees.
An estimated 65 mph wind gust occurred in Marble Rock that blew down trees and power lines. Two large, empty fertilizer bins were blown off their foundation.
