Category One Hurricane: What Winds Can Do

Here's a description provided by the National Hurricane Center explaining exactly what kind of wind damage can be caused by a Category One hurricane. This is according to the Saffir-Simpson Hurricane Wind Scale.:

Category One Hurricane (Sustained winds 74-95 mph, 64-82 kt, or 119-153 km/hr).
Very dangerous winds will produce some damage

People, livestock, and pets struck by flying or falling debris could be injured or killed.
Older (mainly pre-1994 construction) mobile homes could be destroyed, especially if they are not anchored properly as they tend to shift or roll off their foundations. Newer mobile homes that are anchored properly can sustain damage involving the removal of shingle or metal roof coverings, and loss of vinyl siding, as well as damage to carports, sunrooms, or lanais.
Some poorly constructed frame homes can experience major damage, involving loss of the roof covering and damage to gable ends as well as the removal of porch coverings and awnings. Unprotected windows may break if struck by flying debris. Masonry chimneys can be toppled. Well-constructed frame homes could have damage to roof shingles, vinyl siding, soffit panels, and gutters. Failure of aluminum, screened-in, swimming pool enclosures can occur. Some apartment building and shopping center roof coverings could be partially removed. Industrial buildings can lose roofing and siding especially from windward corners, rakes, and eaves. Failures to overhead doors and unprotected windows will be common.
Windows in high-rise buildings can be broken by flying debris. Falling and broken glass will pose a significant danger even after the storm. There will be occasional damage to commercial signage, fences, and canopies. Large branches of trees will snap and shallow rooted trees can be toppled.
Extensive damage to power lines and poles will likely result in power outages that could last a few to several days.
Hurricane Dolly (2008) is an example of a hurricane that brought Category 1 winds and impacts to South Padre Island, Texas.
