The hurricane season for the Atlantic, Caribbean, and Gulf of Mexico runs from June 1st through November 30th and it will close out on Tuesday tied for the 3rd busiest season on record. In the eastern North Pacific, however, it was the quietest season on record. These extremes in hurricane activity were due to La Nina conditions (cooler than normal surface water), in the equatorial Pacific Ocean. The 19 named storms in the Atlantic basin produced 12 hurricanes of which 5 became major storms (111 mph winds or higher).
