(8/3/14, 2:30 p.m. EDT) -- Tropical Storm Bertha is now about 150 miles southeast of San Salvador, bringing maximum sustained winds of 45 miles per hour. It's expected to continue moving toward the north-northwest, north and north-northeast, with some strengthening in the next 48 hours. A tropical storm warning is in effect for Turks and Caicos, and parts of the Bahamas. Carnival spokeswoman Jennifer De La Cruz tells us Carnival Valor had no issues returning to San Juan, and the next sailing is expected to depart on time. Royal Caribbean spokesman Harry Liu reports that Enchantment of the Seas was forced to skip a call on CocoCay, the line's private island. It spent the day at sea instead.
(8/2/14, 2:30 p.m. EDT) -- Tropical Storm Bertha, currently swirling about 110 miles west-southwest of Puerto Rico, has caused at least one cruise line to make changes to a handful of its ships' itineraries.
The National Hurricane Center says the storm, which has maximum winds of 50 miles per hour, continues to move west-northwest at about 22 miles per hour. As many as 8 inches of rain are possible throughout the area.
Several watches and warnings have been issued for Puerto Rico, the U.S. and British Virgin Islands, Turks and Caicos, and parts of the Bahamas and the Dominican Republic.
Carnival Breeze: The order of Breeze's itinerary has been rearranged to avoid the storm, putting a scheduled call on Grand Turk at the end of the voyage. All ports still remain on the itinerary, just in a different order.
Carnival Liberty: Carnival Liberty's August 1 sailing will replace a Sunday call on Grand Turk with a Friday call on Nassau. The order of the remaining ports -- San Juan, St. Thomas and St. Maarten -- has also been switched.
Carnival Valor: Carnival is currently monitoring the storm's effect on San Juan, as Carnival Valor is scheduled to end its current sailing there on Sunday. If the ship is delayed returning to port, it will affect both the current sailing and the subsequent voyage.
Royal Caribbean also has ships in the area, but it reports that there have been no changes so far.
We'll update this story as more information becomes available.
