A Category 1 is a minor but still quite intense tropical cyclone with winds of 74-95 mph (119-153 km/h or 64-82 kt) and a barometric pressure of 980 to 994 millibars. Category 1 hurricanes can blow poorly attached roof shingles off, uproot trees, and can topple unanchored mobile homes. An example of a Category 1 was Hurricane Chris in 2012 (pictured below).
