Deer Lodge, the town this property stands in, in 28 storm reports between 1993 and 2014: 23 hail, 2 thunderstorm wind, 1 flood, 1 heavy rain.
No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
According to a spotter 1 mile west of Deer Lodge 0.80 of rain fell in a time span of 20 minutes. This rain resulted in street flooding in the town of Deer Lodge with water lapping doors of many businesses. The Powell County fair and rodeo were impacted by the flooding especially the fairgrounds exhibition center. Prisoners from the state prison were summoned to help setup sandbags to help mitigate the flooding.
A person from the public west of Deer Lodge estimated that quarter size hail fell during this event. Also a trained spotter located 1 mile west of Deer Lodge measured pea size hail and reported that large amounts of it had fallen.
