FORT LAUDERDALE, Fla. (AP) - The director of the National Hurricane Center says the potential for a new catastrophe in Haiti is his biggest concern for the upcoming Atlantic storm season.

Director Bill Read could offer little help to Haitians who have been living under flimsy tents since the Jan. 12 earthquake. He warned people to move out of low-lying areas, as Haiti's bare, mountainous landscape leaves the Caribbean country vulnerable to flooding even in strong rainstorms.

Read says the oil spill in the Gulf of Mexico will have little effect on any storms that develop in those waters, but a hurricane could help break it up. Read will address the annual Florida Governor's Hurricane Conference in Fort Lauderdale later Wednesday. The six-month Atlantic hurricane season begins June 1.
