To get an idea of the straight line wind damage over a wide area, a sustained wind gust of 136 km/h (84 mp/h) was recorded just north of Toronto at the Buttonville Airport, which was located on the far southern periphery of the main derecho. Many thousands of trees were blown down across the province severing power lines, blocking roadways, and damaging homes. One person was killed, and dozens of people were injured. Eight people trapped in flipped houseboat in Pigeon Lake near Peterborough were rescued hours after the storm. Power was not restored to some affected areas for up to a week after the event. The derecho caused CAN$53 million in damage. The storm entered New York state at around 4 A.M. The storm slammed into the Adirondacks felling 900,000 acres (3,600 km²) of forest. The value of the loss of timber was estimated at over $200 million (1995 dollars) ($306M in 2014 dollars) The derecho passed through the Syracuse airport with a 76 mph wind gust. A parked Boeing 727 was blown into another plane. A 77 mph wind gust was recorded at Albany. It moved into New England a little after sunrise producing 70-90 mph wind gusts in several towns in Massachusetts. Fifty people were left homeless after the derecho blew the roof off an apartment building in Holyoke, Massachusetts. Three people were injured in Deerfield, Massachusetts when a hot air balloon got caught into the winds of the derecho gust front and blew into a tree. During the July 15, 1995 derecho, over 600 lightning strikes were observed in a 10-minute period during the storms peak intensity. 600 lightning strikes in 10 minutes translates into 60 strikes a minute or one strike every second. A Lightning Detection System (LDS) displayed flash rates of 3000 strokes per hour. Satellite photography depicted expanding cloud tops to 75,000 feet. The Ontario-Adirondacks Derecho was the strongest of the derecho events of the previous days and is among the costliest thunderstorms in US/Canadian history. It caused $500 millions in damage. Altogether, the four derecho events caused nearly $1 billion in damage.
