Hurricane Jose was a powerful Category 4 hurricane that threatened the Leeward Islands, which had been devastated by Hurricane Irma days earlier, but ultimately stayed at sea. The tenth named storm, fifth hurricane, and third major hurricane of the hyperactive 2017 Atlantic hurricane season, Jose formed from early on September 5 from a tropical wave in the tropical Atlantic Ocean. It quickly intensified into a hurricane the following day, and rapidly intensified to reach its peak intensity with sustained winds of 155 mph (250 km/h) and a minimum pressure of 938 millibars on September 8. However, reconnaissance data suggests that Jose briefly reached Category 5 strength, although this was dismissed in the National Hurricane Center's post-season report on the storm. Afterward, Jose began to weaken as its appearance began to degrade. It weakened to a tropical storm on September 14 as it executed an anti-cyclonic loop, but it regained hurricane status the next day. Jose weakened to a tropical storm once again on September 20, and two days later it became post-tropical off the coast of New England. Jose's remnants finally dissipated on September 26.
