What can winds at 80 mph move?

Winds of that velocity can break off tree branches and even blow over whole trees, particularly if they have weakened roots or compromised soil. Some gas station awnings (and covered parking awnings) may blow down. Lots of wood fences blown down. Some back-lighted signs will be blown out. In downtown areas with many tall glass-covered buildings, a small amount of flying debris can break a window, releasing flying glass, which hits more Windows, causing a chain reaction.

Well-constructed houses and buildings should not suffer significant damage. Unanchored cottages and mobile homes are likely to be shifted off their foundations.

In general, automobiles will not move. Fujita (1979) calculated that a wind speed of 87 mph could slide a 2,400 lb car off its resting position. However, empirical data sets the threshold higher. Rasmussen reported that a stationary 1993 Ford Tempo sedan withstood 98 mph wind with no damage and did not move. Castor reported that his 1990 Chevrolet full-size four-wheel-drive pickup experienced a gust of 105 mph without damage and did not move. In wind tunnel experiments, a minivan (the most susceptible passenger vehicle tested) could be tipped over at 130 mph. At 95 mph, high-profile vehicles (trucks, semis, buses) may tip over, but cars, vans and pickups are not affected.
