The Colorado State University hurricane center predicts an average season this year with 13 named storms in the Atlantic.
The center predicts six hurricanes with two of them expected to be major.
The center at the Department of Atmospheric Science at the university said there is a 40 percent chance of a major Caribbean hurricane.
The experts, Philip J. Klotzbach and William M. Gray, said that the current weakening of El Niño is likely to change to either a neutral or a La Niña condition by the peak of the hurricane season.
The tropical Atlantic, they said, is relatively warm and the North Atlantic is quite cold. The cold creates conditions that are not conducive to the formation of hurricanes and their intensification, they said.
The forecast is based on 29 years of data. The Atlantic already had one hurricane this year, Alex, which took place in January. That was unusual because the hurricane season usually is considered to be from June 1 to Nov. 30.
However, the experts note that hurricanes can happen at any time.
The 2015 hurricane season was abnormally low, perhaps due
to El Niño. There were just four hurricanes, and two of them were major.
Costa Rica has seen very few hurricanes in historic times, but the backlash from many have caused major flooding and other problems, particularly in the western part of the country.
The eastern north Pacific hurricane season runs from May 15 through Nov. 30, and last year was the second most active season on record with 16 hurricanes. Typically the storms head northwest, although some can touch México.
The U.S. National Oceanic and Atmospheric Administration has yet to make a prediction.
