Well-known U.S. storm forecaster William Gray has predicted an active Atlantic hurricane season.
Gray and his team at Colorado State University say 17 tropical storms can be expected this season, with nine of them becoming hurricanes. He added that five of the storms will be major hurricanes.
Last week, officials at the U.S. National Oceanic and Atmospheric Administration (NOAA) predicted there will be up to 16 named storms. They said they expect 10 of them to become hurricanes, and that six of them could become major hurricanes.
The Atlantic hurricane season runs from June 1 through November 30.
NOAA and Gray say the world is in a 20-year cycle that will continue to bring strong storms.
The 2005 storm season was the most destructive in recorded history, with seven major hurricanes, including Katrina, which killed some 1,300 people along the U.S. Gulf Coast.
