As Hurricane Rina continues to strengthen and a hurricane warning was issued for part of Mexico’s Yucatan Peninsula, Carnival Cruise Line changed itineraries for eight ships and Celebrity Cruises changed the itinerary for Celebrity Millennium.

Tropical Storm Maria is impacting the itinerary of Norwegian Cruise Line’s Norwegian Gem. The ship, which departed from New York on Sunday, will avoid the path of the storm by sailing to the Bahamas and Florida instead of Bermuda.

A greatly weakened Hurricane Katia was expected to pass between the US east coast and Bermuda in the next two days without making landfall, forecasters from the National Hurricane Center said Wednesday.

The latest advisory from the National Hurricane Center and analysts at NASA's Goddard Space Flight Center have included probabilities that Hurricane Katia could potentially make landfall in the New York City region.

The National Hurricane Center, in its latest advisory on Wednesday morning, says Tropical Storm Katia is gradually gaining strength as it moves quickly west-northwestward. Yesterday morning Katia was estimated to have maximum sustained winds of 65 miles per hour and was moving west-northwestward at 21 mph.

The Puerto Rico Tourism Company (PRTC) said Puerto Rico is open for business and fully operational for tourists after Hurricane Irene passed through last week. All hotels, casinos, airports and ferries are operating as normal on the main island as well as Culebra and Vieques.
