(6:12 p.m. EDT) -- Storms off the coast of Mexico in the Pacific Ocean have caused Carnival Cruise Line to make itinerary changes to its ship sailing the Mexican Riviera.

As of Friday, September 20, Hurricane Lorena was forecast by the National Hurricane Center to bring heavy rainfall and winds to Mexico's Baja Peninsula, where the popular port Cabo San Lucas is located. Tropical Storm Mario is not forecast to hit land at this time, but the agency warned that the storm's track was uncertain.

Carnival Splendor will be visiting ports in reverse order on its sailing from Long Beach, Calif., on Saturday, September 21. Instead of going to Cabo San Lucas on Monday, September 23, the ship will go to Puerto Vallarta, then Mazatlán as scheduled. It will stop in Cabo on Wednesday, September 25.

Cruise Critic will continue to monitor the storms and update when needed.
