Torrents of rain and hail fell on Butte in an hour-long thunderstorm which dumped over 2 inches of rain and hail over most of urban Butte. Blacktail Creek was over its banks in many areas. Silver Bow Creek, which normally has little or no water in the summer, was running like a river. Montana and Harrison Ave. streets were flooded and impassable during the peak of the storm. Debris from the hill washed down large rocks and boulders, which covered many of the streets in the up-town area. Underground power lines were washed out with residents without power for two to three days. Many private homes suffered flooded basements, yards and garages. Two trailer parks, located at the bottom of hills, suffered major damage. Centerville Volunteer Fire Dept. had major water damage.
