The El Nino, which warms part of the Pacific every few years and changes rain and temperature patterns around the world, will likely reduce the number and intensity of tropical storms and hurricanes, the National Oceanic and Atmospheric Administration said in New York City.
Cooler temperatures on the surface of the Atlantic Ocean compared with recent years will also lower the probability of hurricane formation.
Officials expect about eight to 13 named tropical storms and three to six hurricanes. Just one or two major hurricanes with winds over 110 miles per hour are forecast.
The six-month storm season begins June 1.
Forecasters got it wrong last year when they predicted an unusually busy hurricane season. There were just 13 named storms and two hurricanes, Umberto and Ingrid, both of which were Category 1, the lowest on the scale that measures hurricanes by wind speed. There were no major hurricanes.
In 2012, storm surge was devastating to the New York area when Superstorm Sandy slammed the East coast, killing 147 people and causing $50 billion in damage. Sandy lost hurricane status when it made landfall in New Jersey.
A new mapping tool this year will keep coastal residents updated on the storm surge threat in their communities.
The Atlantic hurricane season goes through cycles of high and low activity about every 25 to 40 years based on large scale climatic patterns in the atmosphere. Since 1995, an average season has 15 named tropical storms, eight hurricanes and about four major storms. The last time a major hurricane made landfall in the U.S. was when Wilma came ashore in 2005, an eight-year stretch that is the longest on record.
During the six-month season, forecasters name tropical storms when top winds reach 39 mph; hurricanes have maximum winds of at least 74 mph.
