As Hurricane Irene makes her way through the Caribbean, a hurricane warning is in effect for the north coast of the Dominican Republic from the Haiti border eastward and in the southeastern Bahamas and Turks and Caicos Islands. By mid-day today, Weather.com has "increased the threat along Florida and southeast United States coast to HIGH. This threat level will likely change as forecast confidence increases both in the track and intensity. Other areas of the U.S., perhaps farther north along the East Coast."
As a precaution, Carnival Cruise Lines has altered more of their ships' itineraries:
Carnival Conquest, sailing a scheduled 7-day Bahamas and Florida cruise that left Galveston yesterday, will now sail a Western Caribbean itinerary. Port calls will include Costa Maya on Wednesday, Cozumel on Thursday, and Progreso on Friday.
Carnival Victory, currently on a 7-night cruise from San Juan, cancelled today's visit to St. Thomas and is presently sailing to Barbados for its scheduled Wednesday port call. The remainder of the itinerary is being evaluated.
