Hurricane Kate was the latest Atlantic hurricane by calendar date to make landfall in the United States. The eleventh named storm, seventh hurricane, and third major hurricane of the 1985 Atlantic hurricane season, it was the final in a series of tropical cyclones to impact the United States during 1985. Kate originated from the interaction of an upper-level trough and tropical wave northeast of Puerto Rico on November 15. Though the system tracked erratically during the first hours of its existence, the intensification of a region of high pressure to the cyclone's north caused Kate to turn westward. A favorable atmospheric pattern allowed the newly developed system to intensify to hurricane intensity on November 16, and further to Category 2 intensity three days later. Category 3 hurricane: peak winds of 120 mph (105 knots), lowest pressure 954 mb. November 15 – November 23, 1985. Landfall: November 21 at 100 mph, 30.0°N 85.4°W. Accumulated cyclone energy: 19.1.
