of three that Minnesota suffered hits from derecho winds—five million trees were blown down and buildings were damaged or destroyed, and six campers were injured by falling trees in the early morning hours. The derecho moved south and southeast during the afternoon hours and blew more trees down. Three people were killed and several injuries occurred in eastern Michigan. In Roscommon County, 100,000 trees and 100 miles of power lines were blown down. In Detroit, Michigan, 400,000 people lost power. It was the biggest power loss for the city since the July 7, 1991 derecho event. The power loss only added to what might have been a very uncomfortable situation. As previously mentioned, Detroit was in a massive heat wave. Luckily, the heat was mitigated by cooling from rain. The derecho wreaked havoc in southwestern Ontario, hundreds of trees fell and damage was caused to buildings. When the derecho crossed Lake Erie, the storm capsized many boats and one man was killed. The derecho moved into Ohio and felled thousands of more trees. Three more people were killed and several more were injured. The derecho finally dissipated near the Ohio River at midnight on July 14. Amazingly, this was not the only major heat wave of July 1995. At the end of the month and the beginning of August, another major heat wave spread across the country. An example of this was the 128 degrees Fahrenheit registered on July 28 in Indio, California. The Ontario-Adirondacks Derecho of July 14 and 15 The Ontario-Adirondacks Derecho got its start near the straits of Mackinac on Friday evening July 14, 1995. At the Mackinac Bridge connecting the Upper and Lower Peninsulas of Michigan, 100 mph winds were detected and sustained winds above 80 mph continued on the bridge for 10 additional minutes. After crossing the open waters of Lake Huron/Georgian Bay, the storm raced southeastward into central southern Ontario. Several brief tornadoes were reported. An F1 tornado struck the Balsam Lake Trailer Park near Kirkfield, flipping over vehicles, destroying several trailers and sending ten people to hospital with non life-threatening injuries. One trailer was thrown over 250 meters. Across the lake from the trailer park, straightline winds caused extensive damage in the cottage community of Long Point. Further east, near Peterborough, an F2 tornado hit Bridgenorth damaging or destroying 20 homes and a marina with winds estimated upward of 200 km/h (120 mp/h).
