caption_attribution_description: English: Track map of Hurricane Leslie of the 2018 Atlantic hurricane season. The points show the location of the storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir–Simpson scale (see below), and the shape of the data points represent the nature of the storm, according to the legend below.

context_page_description: The 2018 Atlantic hurricane season was an event in the annual hurricane season in the north Atlantic Ocean. It as an above-average season for tropical cyclones for the third consecutive year. Though the season officially began on June 1, 2018 and ended November 30, 2018, dates adopted by convention and historically describe the period during each year when most tropical cyclones form, it effectively started with the formation of Tropical Storm Alberto on May 25. The season's final storm, Hurricane Oscar, dissipated on October 31.
  The year produced sixteen tropical depressions, all but one of which further intensified into named tropical storms. Of the fifteen named storms, eight developed into hurricanes, and two further intensified into major hurricanes, which are rated Category 3 or higher on the Saffir–Simpson scale. These two major hurricanes contributed to a majority of the season's severe destruction and loss of life, mainly in the United States.
  Hurricane Florence formed near Cabo Verde on August 31, steered toward the west-northwest with little exception by a large area of high pressure to its north.
