The 2015 Atlantic hurricane season has ended. Hurricane season runs from June 1 to November 30, in the Atlantic ocean. That includes the Caribbean, and the Gulf of Mexico. Those 6 months are when tropical depressions, tropical storms, and hurricanes are most likely to form.
This year, 11 named storms formed. 4 of those storms became hurricanes. While the total number is below average, average is just an average of many years so the total number is in the range of typical. The eastern and central Pacific were more active than average.
Two tropical storms directly impacted the United States- Ana
While the hurricane season has ended, tropical storms have formed or lasted into every month except for February. Technology lets us see things that we may have missed in the past so it wouldn’t be totally unusual to have a tropical depression or tropical storm outside of the calendar season.
