Max Mayfield, whose calm voice but resolute manner guided South Floridians and millions of others through some of the worst hurricane seasons in history, will retire as director of the National Hurricane Center and intends to leave in January, he told his staff this afternoon.

''No one event has caused this,'' he told shocked forecasters during the usual afternoon ''map discussion'' to review conditions in the hurricane zone. "'I've been here 34 years and as Forrest Gump said in the movie, 'I'm tired and I want to go home.' ''

The staff expected to hear only about Tropical Storm Debby and Tropical Depression 5, which is expected to grow into Tropical Storm Ernesto as it moves through the Caribbean.

Along with that, they heard the bombshell announcement, which took less than a minute.

''My last day is going to be Jan. 3,'' he told his forecasters and support staff. "Let's give it everything we've got. Now, get back to work.''
