CANCUN, Mexico – Officials readied storm shelters along Mexico's Caribbean coast Saturday and told fishermen and tour operators to pull in their boats as Ida strengthened into a hurricane as it neared the resort city of Cancun.
The U.S. National Hurricane Center in Miami said Ida's winds had picked up to 75 mph (120 kph), making it a Category 1 storm.
The hurricane was on a path that would take it through the middle of the Yucatan Channel that separates Mexico and Cuba on Sunday. Forecasters predict Ida will enter the Gulf of Mexico, eventually weaken again to tropical storm strength and possibly brush the U.S. Gulf Coast next week.
As rain began pelting down in Cancun, the beaches were empty but tourists walked the streets under umbrellas or improvised rain ponchos.
Realtor Beth Conway, 41, from Sacramento, California, said she was happy just to be in Cancun.
"We don't really care if it's rainy or sunny," Conway said as she gathered her luggage at the Cancun airport. "We were just hoping they weren't going to cancel our flight."
The storm caught others by surprise. "What storm? I checked the weather three nights ago. I didn't think to check it again," said Rafah Adoulhosn, 29, a pharmacist from San Antonio, Texas, who plans to spend a week in nearby Playa del Carmen.
"I had a week off. We had to take advantage of it," said her boyfriend, 31-year-old surgical resident Adham Saad.
Tropical-storm warnings were issued for the Mexican coastline from Punta Allen, south of Tulum, to San Felipe at the top of the Yucatan Peninsula, an area that includes Cancun. The warnings were also in effect for western Cuba and Grand Cayman Island.
A hurricane watch was in effect from Tulum to Cabo Catoche.
Authorities started up a reporting system used to locate tourists and plan potential evacuations or shelters. Quintana Roo state Tourism Director Sara Latife Ruiz said there were about 36,000 foreign and Mexican tourists in Cancun.
"We can locate them and if necessary, take them to some temporary shelter," said Latife Ruiz. "Right now, no flights have been canceled ... and there has been no evacuation of tourists."
State civil defense Director Luis Carlos Rodriguez said "there is still time to protect property, so we have advised fishermen, small boat owners and those living in low-lying areas of Tulum, Holbox, Cancun and Playa del Carmen to take safety measures for their property."
Late Saturday, Ida was centered about 120 miles (193 kilometers) east-southeast of Cozumel and moving northwest at about 12 mph (19 kph).
Juan Granados, assistant director of civil defense, said seven storm shelters were being readied on Cozumel, five on Isla Mujeres and seven on Holbox, an island north of the peninsula. Statewide, dozens more were being readied for use if needed.
Authorities suspended fishing along part of the coast and told tour operators who offer reef snorkeling and diving excursions to stay in port, Granados added.
"We'll get some wind and rain, but that's about it," said James Watts, 34, part of a family from British Columbia, Canada that runs The Summer Place Inn and a real estate firm on the island of Cozumel, near Cancun.
Employees at the inn weren't taping up or boarding over windows, but Watts said small boats would be pulled ashore, adding "we'll put some sandbags in them to keep them from going anywhere."
Popular Mayan sites such as the seaside ruins of Tulum were to remain open, but employees worked to clean up debris that could become a hazard in high winds, Mexico's National Institute of Anthropology and History said in a statement.
John Cangialosi, a specialist at the Hurricane Center, said that as Ida heads north across the Gulf of Mexico, it is expected to meet a cold front that is moving south — making longer-term forecasts complicated for now.
"There's going to be some sort of interaction between the two, but where they interact, and how, and the timing of the thing, that's kind of the big question mark," Cangialosi said.
Regardless of how the cold front affects the tropical system, Cangialosi said residents on the north Gulf Coast can expect lots of wind and heavy rain.
Ida plowed into Nicaragua's Atlantic coast on Thursday as a Category 1 hurricane, damaging 500 homes along with bridges, power lines, roads and public buildings.
Cuba's national Meteorological Center said it did not expect any direct impact from the storm, but noted it could cause heavy rains in the western province of Pinar del Rio.
The Hurricane Center said a hurricane warning might be needed for the province by late Sunday.
