The director of the National Hurricane Center in Miami says hurricane experts are worried about the thousands of Katrina evacuees living in temporary housing.
Max Mayfield is speaking at the National Oceanic and Atmospheric Administration's four-day conference in Mobile, Alabama.
Last year's Atlantic hurricane season was the busiest on record, with Category Four Katrina's August 29 destruction the worst on record.
According to NOAA, the season included 27 named storms, including 15 hurricanes in which seven were major, Category 3 or higher.
Hurricane researcher Jay Baker of Florida State University says his studies show that residents are more likely to heed evacuation orders if they come from local officials.
The hurricane season starts June 1.
