The top U.S. hurricane expert said Thursday that this year's hurricane season is likely to be stronger than average, though short of the record 2005 season, the costliest on record.
But he warned that this year's hurricane season, which officially begins on June 1, might be stronger than average.
"I think everybody is going to say we're going to have an above-average season here," Mayfield told a news conference at a San Juan hotel, adding: "We don't have the numbers worked out yet."
A record 27 tropical storms formed in 2005, with seven becoming major hurricanes — including four that made landfall in the United States.

The National Oceanic and Atmospheric Administration's National Hurricane Center and National Centers for Environmental Prediction will release their official hurricane forecast on May 22.
Researchers are trying to better understand storm intensity, particularly after last year's Hurricane Wilma jumped from a tropical storm to a whopping Category 5 hurricane within 24 hours.
D.L. Johnson, director of the NOAA's National Weather Service, said his people are preparing to put up the next generation of weather satellites and want to improve monitoring of upper air currents to help determine where storms will go.

The region has experienced strong hurricanes since 1995, due in part to warm sea surface temperatures, participants said.
"We need to remember that the research community is telling us that we are in this active period for hurricanes that may very well last another 10 to 20 years," Mayfield said. "And that's not good news for this region."
The first tropical storm of the 2006 season will be named Alberto.
