I think that they call them straight-line winds and VERY destructive. If there is a server thunder storm this can happen. Goggle it and find the way these things happen. I believe what happens is winds come down from a strong storm and then hits the ground and heads in a direction and the winds are VERY-VERY strong. This the name straight-line winds.We see a lot of them here in IA, but they happen all over.

The Winds are known as a "Derecho", I was Camping at Lake Ontario in July 1995, at Southwick Beach State Park (Less than 10 miles from where Green Point Marina is located, and the above picture was taken last week), at 4:15 AM we had a Derecho hit with 100+ MPH Winds, my group was fortunate, as we escaped without any damage, many others were not as fortunate, as this excerpt from the NOAA tells:
JULY 1995 DERECHO
...NEW YORK...
As the Ontario-Adirondacks Derecho entered New York (NY) around 4 to 4:30 AM EDT, very severe wind damage continued to occur, especially along most bowed out portion of the line of thunderstorms. Winds estimated to be 100 mph or greater occurred at several points along a band from Jefferson and western St. Lawrence Counties through the Adirondack Mountain region. Of the five deaths and 11 injuries associated with the derecho event in New York, most were the result of trees falling on campers in the Adirondacks. Over 30 campers and hikers in the area had to be removed by helicopter since their paths out of the forest were blocked by thousands of fallen trees. According to the New York Dept. of Conservation about 900,000 acres of forest were damaged in the state and the value of the loss of timber was estimated to be over 200 million in 1995 U.S. dollars.
In the more populated areas of central and eastern New York almost 190 million in 1995 U.S. dollars in damage was done to structures and vehicles. Many mobile homes were overturned and numerous homes and businesses were damaged. Many vehicles were damaged or destroyed by falling trees. At the Syracuse Airport a wind gust of 76 mph was measured at 5:30 AM EDT as the storm gust front passed through and a parked Boeing 727 jet plane was blown into another commercial jet plane at the airport terminal. Less than an hour later a gust of 77 mph was recorded at the Albany airport. Several hundred thousands of people lost electrical power due to the powerful derecho winds.
