    tropical storm forms in the basin every other year in the month of
    Overall, the 2019 Atlantic hurricane season featured above normal
    activity. Eighteen named storms formed, of which six became
    hurricanes and three became major hurricanes - category 3 or higher
    on the Saffir-Simpson Hurricane Wind Scale.  This compares to
    the long-term average of twelve named storms, six hurricanes, and
    three major hurricanes. There were also two tropical depressions
    that did not reach tropical-storm strength. In terms of Accumulated
    Cyclone Energy (ACE), which measures the combined strength and
