The U.S. National Weather Service has issued their 2015 Atlantic Hurricane Season Outlook.
They are predicting a less active than normal hurricane season.
Named storms: 6-11 (normal is 12)
Hurricanes: 3-6 (normal is 6)
Major hurricanes: 0-2 (normal is 3)
Of course, this does not mean that a tropical storm or hurricane cannot hit the Riviera Maya.
