GEORGE TOWN, Cayman Islands Oct 16, 2005 — A tropical storm warning was in effect for the Cayman Islands on Sunday and residents began preparing for the worst.

The system could become Tropical Storm Wilma, which would make it the 21st named storm of the season, tying the record for the most storms in an Atlantic season, the National Hurricane Center in Miami said.

The only other time that many storms have formed since record keeping began 154 years ago was in 1933, when Franklin Delano Roosevelt was president and the United States was in the midst of the Great Depression.
