The 2016 Atlantic hurricane season was the costliest, as well as the first above-average, Atlantic hurricane season in four years. It featured the highest number of deaths since the 2008 season and also yielded the highest number of named storm landfalls on the United States since that year. The season officially began on June 1 and concluded on November 30, dates which conventionally delimit the period during each year when a majority of tropical cyclones form in the Atlantic Ocean. The season's first cyclone, Alex developed on January 12, while the final storm of the season, Otto, ultimately dissipated on November 26.
A total of 16 tropical depressions were recorded, of which 15 further intensified into tropical storms. Of those 15, a total of 7 strengthened into hurricanes, while 2 attained their peaks as major hurricanes. Activity began with Alex which, upon making landfall in the Azores, became the first January landfalling tropical cyclone since Hurricane Alice in the 1954 season. In June, tropical storms Colin and Danielle became the earliest third and fourth named storms, respectively, on record.Hermine moved ashore the coastline of Florida as a Category 1 hurricane on September 2, ending the record hurricane drought that began in the state after the 2005 season's Hurricane Wilma. In late September and early October, Hurricane Matthew wrought destruction throughout the Caribbean Sea and Southeastern United States, resulting in $15.09 billion (2016 USD) in damage and 603 deaths; it remains the ninth-costliest hurricane on record in the Atlantic, as well as the tenth-costliest in the United States. In mid-October, Hurricane Nicole ascended to Category 4 intensity and remained a major hurricane while directly impacting Bermuda, the first storm of such strength to do so since Hurricane Fabian in the 2003 season. The season concluded with Hurricane Otto, the latest-forming major hurricane on record in the Atlantic and the first cyclone to cross from the basin into the East Pacific since Hurricane Cesar–Douglas.
