The thirteenth named storm, seventh hurricane, and second major hurricane of the 2018 Atlantic hurricane season, Michael originated from a broad low-pressure area that formed in the southwestern Caribbean Sea on October 2. The disturbance became a tropical depression on October 7, after nearly a week of slow development. By the next day, Michael had intensified into a hurricane near the western tip of Cuba, as it moved northward. The hurricane strengthened rapidly in the Gulf of Mexico, reaching major hurricane status on October 9, peaking as a high-end Category 4 hurricane on the Saffir–Simpson scale becoming the strongest Atlantic hurricane to form in the month of October since Hurricane Wilma. It was also approaching the Florida Panhandle, Michael attained peak winds of 155 mph (250 km/h) as it made landfall near Mexico Beach, Florida, on October 10, becoming the first to do so in the region as a Category 4 hurricane, and making landfall as the strongest storm of the season. As it moved inland, the storm weakened and began to take a northeastward trajectory toward Chesapeake Bay, weakening to a tropical storm over Georgia, and transitioning into an extratropical cyclone off the coast of the Mid-Atlantic states on October 12. Michael subsequently strengthened into a powerful extratropical cyclone and eventually impacted the Iberian Peninsula, before dissipating on October 16.
