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 only other time so 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 Depression.
Long-term forecasts show the storm would likely move west and north, putting the storm in the Gulf of Mexico later this week. Forecasters say water temperature and other conditions were favorable for it to become a significant hurricane.
A hurricane watch was issued for the Cayman Islands, meaning hurricane conditions could be felt there within 36 hours. A tropical storm warning, meaning tropical storm conditions within 24 hours, also was posted.
