(CNN) -- University forecasters predict the 2010 Atlantic hurricane season will be above average, with 15 named storms and eight of those becoming hurricanes.
The Colorado State University report was released Wednesday, nearly two months before the beginning of the Atlantic hurricane season on June 1.
In the report, forecasters William Gray and Phil Klotzbach said that El Niño conditions will dissipate by summer and that unusually warm tropical Atlantic sea surface temperatures will persist, leading to favorable conditions for hurricanes to develop and intensify.
Of the eight expected hurricanes, the forecasters predict that
four will strengthen to major hurricanes, meaning Category 3 or higher on the Saffir-Simpson scale of strength. Category 3 storms have sustained winds of at least 111 mph.
The forecast said the probability of a major hurricane making landfall along the U.S. coastline is
69 percent. It said there was
a 58 percent chance of a major hurricane tracking into the Caribbean.
However, the two forecasters emphasize the forecast is preliminary and that revised ones will be released on June 2 and August 4.
"We issue these forecasts to satisfy the curiosity of the general public and to bring attention to the hurricane problem," the report said.
Gray and Klotzbach said that precursors to this year's hurricane season are similar to
early April conditions ahead of the 1958, 1966, 1969, 1998 and 2005 seasons.
See below for storms from these years."All five of these seasons had above-average activity, especially the seasons of 1969, 1998 and 2005," a statement from Colorado State University said.
However, Klotzbach and Gray predict the 2010 season will have slightly less activity than the average of these five earlier years.
Last year's hurricane season was below average, with nine named tropical storms, three of which were hurricanes. The National Hurricane Center said it was the lowest number of tropical storms for the Atlantic basin since 1997.
Klotzbach and Gray put out four predictions for each hurricane season, beginning in December before the season begins.
A typical season has 11 named storms, six hurricanes and two major hurricanes, according to the National Oceanic and Atmospheric Administration.
The hurricane season will end November 30, but later storms have been known to happen.

1958 Atlantic hurricane season
Notable 1958 storms include Hurricane Cleo which reached Category 5 intensity on the Saffir-Simpson Hurricane Scale while remaining in the open Atlantic Ocean; Hurricane Ella, which dumped considerable amounts of rain in southern Texas; Tropical Storm Gerda, which killed three in Puerto Rico; and Hurricane Helene, which caused $7 million in damage (1958 dollars) when it skimmed past Cape Fear, Cape Lookout (North Carolina), and Cape Hatteras.
1966 Atlantic hurricane season
Notable storms of 1966 include Hurricane Alma, which caused death and destruction in Honduras, Cuba, and Florida; and Hurricane Inez, which killed 1,000 people in its trek across the Greater Antilles, Bahamas, Florida, and Mexico. An unusual storm was Hurricane Faith, which followed an extremely long track from Africa, into the Caribbean, and all the way into the Arctic. It holds the record for having the longest hurricane track in recorded history.
1969 Atlantic hurricane season
The most notable storm of the season was
Hurricane Camille, the seventh-strongest storm recorded in the Atlantic basin and the second-strongest to make landfall in the United States. Camille made landfall near Bay St. Louis, Mississippi as a Category 5 hurricane on the Saffir-Simpson Hurricane Scale, killing 256 and causing $1.4 billion ($9.2 billion in 2005 dollars) in property damage.
Other notable storms include Hurricane Francelia, which caused serious flooding in Belize that killed 100; Hurricane Inga, which lasted almost 25 days and was at the time the second longest-lasting hurricane; and Hurricane Martha, which caused flooding and landslides in Costa Rica and Panama.
1998 Atlantic hurricane season
The most notable storms of the season were Hurricane Georges and Hurricane Mitch. Hurricane Georges caused heavy damages across the Caribbean Sea and on the United States' Gulf Coast as well as 604 deaths. Hurricane Mitch killed at least 11,000 people, mostly in Honduras and Nicaragua, making it the deadliest hurricane of modern times. Another notable hurricane was Hurricane Bonnie which caused $1 billion in damage to North Carolina and Virginia. The worst in those states since Hurricane Fran of the 1996 season.
Total number of fatalities in 1998 was at least 12,000 people, however the exact death toll from Hurricane Mitch is unknown it was estimated between 11,000 to 18,000 people killed. In the Spring of 1999 the World Meteorological Organization retired the names Georges and Mitch. Those two names were replaced by Gaston and Matthew in the 2004 Atlantic hurricane season.
2005 Atlantic hurricane season
The 2005 Atlantic hurricane season was
the most active Atlantic hurricane season in recorded history, repeatedly shattering numerous records. The impact of the season was widespread and ruinous with an
estimated 3,865 deaths and record damages of about $130 billion (2005 USD). Of the storms that made landfall, five of the season's seven major hurricanes—
Dennis, Emily, Katrina, Rita, and Wilma—were responsible for most of the destruction.
The Mexican states of Quintana Roo and Yucatán and the U.S. states of Florida and Louisiana were each struck twice by major hurricanes; Cuba, the Bahamas, Haiti, Mississippi, Texas, and Tamaulipas were each struck once and in each case brushed by at least one more. The most catastrophic effects of the season were felt on the United States' Gulf Coast, where a 30-foot (10 m) storm surge from Hurricane Katrina caused devastating flooding that inundated New Orleans, Louisiana and destroyed most structures on the Mississippi coastline; and in Guatemala, where Hurricane Stan combined with an extratropical system to cause deadly mudslides.
