(2:50 p.m.) Hurricane Norbert has weakened slightly, but could still gain strength as it prepares to hit the Baja Peninsula this weekend.
So far, Carnival, Princess Cruises and Norwegian Cruise Line have announced itinerary changes due the Category Three Hurricane.
Carnival Pride had been due to call in Mazatlan today, but instead it will call in Cabo San Lucas and spend a day at sea on Friday.
Sapphire Princess missed a planned call today at Cabo San Lucas. The ship is heading back to Los Angeles and will arrive there on Saturday as scheduled.
Norwegian Sun's Friday stop in Cabo San Lucas has been cancelled; the ship will instead spend the day at sea.
Winds have decreased to 115 miles per hour, and the storm could still impact other Mexican Riviera itineraries as it edges closer to the coast.
Following Hurricane Norbert further south in the Pacific is the newly formed Tropical Storm Odile, which is currently headed in a west-northwest direction toward the southern coast of Mexico.
We will keep you posted as this storm develops.
