Roslyn weakened from a Category 3 hurricane to a tropical storm Sunday afternoon, the National Hurricane Center said.
The storm was moving inland at 20 mph about 55 miles south-southeast of Durango City, Mexico, with maximum sustained winds of 70 mph at around 1 p.m. local time, according to the hurricane center.
The storm was expected to continue moving farther inland over west-central Mexico into Sunday evening, "with some increase in forward speed," the hurricane center said in its latest update.
"Rapid weakening is expected to continue, and Roslyn is forecast to become a tropical depression by this evening and dissipate tonight or early Monday," the hurricane center said.
The Mexican government discontinued all warnings south of San Blas on Sunday afternoon. The hurricane warning from San Blas to Escuinapa was changed to a tropical storm warning.
Tropical storm warnings also remain in effect for San Blas to Mazatlán.
Tropical storm conditions were expected to spread inland through west-central Mexico through the late afternoon or early evening Sunday.
Tropical storm-force winds extended out to 70 miles, the U.S. hurricane center said Sunday afternoon.
The storm was expected to drop up to 10 inches of rain on the upper coast of Jalisco and Nayarit, including Islas Marías, and up to 8 inches on southeastern Sinaloa and southern Durango into southwestern Zacatecas.
The rain “could lead to flash flooding and landslides in areas of rugged terrain," the hurricane center warned.
Water levels along the coast were expected to subside over the afternoon.
Swells along the country's southwestern coast and west-central region and the southern part of the Baja California peninsula could "cause life-threatening surf and rip current conditions" through Sunday night, the hurricane center said.
Roslyn weakened overnight from a Category 4 to a Category 3 hurricane before it weakened to a tropical storm in the afternoon.
Hurricane Orlene made landfall Oct. 3 a little farther north in roughly the same region as Roslyn, about 45 miles southeast of the resort of Mazatlán.
Seemingly oblivious to the approaching storm, tourists ate at beachside eateries Saturday around Puerto Vallarta and smaller resorts farther north on the Nayarit coast where the storm likely was headed.
“We’re fine. Everything is calm. It’s all normal,” said Jaime Cantón, a receptionist at the Casa Maria hotel in Puerto Vallarta. He said that if winds picked up, the hotel would gather up outside furniture “so nothing will go flying.”
While skies began to cloud up, waves remained normal, and few people appeared to be rushing to take precautions. Swimmers were still in the sea at Puerto Vallarta
“The place is full of tourists,” said Patricia Morales, a receptionist at the Punta Guayabitas hotel in the laid-back beach town of the same name, farther up the coast.
Asked what precautions were being taken, Morales said authorities “haven’t told us anything.”
The head of the state civil defense office, Pedro Núñez, said, “Right now we are carrying out patrols through the towns to alert people so that they can keep their possession safe and keep themselves safe in safer areas.”
In the neighboring state of Jalisco, Gov. Enrique Alfaro wrote that 270 people had been evacuated in a town near the storm's expected path and that five emergency shelters had been set up in Puerto Vallarta.
