After plowing over the Pacific as a powerful Category 4 storm just offshore from Puerto Vallarta, Hurricane Roslyn was expected to bring a dangerous storm surge to parts of Mexico on Sunday.

Roslyn has become "extremely dangerous," according to the National Hurricane Center in the United States, with maximum sustained winds of 215 kilometers per hour.

The hurricane center predicted, "damaging winds, a life-threatening storm surge, and flooding rains to portions of west-central Mexico" at 12 a.m. Sunday.

Roslyn's core was 75 kilometers west of Cabo Corrientes, a point of land jutting into the Pacific south of Puerto Vallarta, and moving north at 19 kilometers per hour.

Forecasters said Roslyn would likely pass close to Cabo Corrientes and the Puerto Vallarta region during the night, but warned that high winds, heavy rains, and rough surf would still be present.

From Las Islas Marias to Playa Perula, a hurricane warning was in effect. The hurricane center issued a hurricane warning for the area north of Escuinapa to Mazatlan.

The storm was expected to make landfall in Nayarit state early Sunday morning. Hurricane Orlene made landfall on October 3 a little further north in roughly the same region, about 75 kilometers southeast of Mazatlan.

A hurricane warning has been issued for the coast from Playa Perula south of Cabo Corrientes north to El Roblito, as well as the Islas Marias.

The hurricane was expected to make landfall around the fishing village of San Blas, about 90 miles (150 kilometers) north of Puerto Vallarta, according to the state government of Nayarit.

Rains from Roslyn could cause mudslides and flooding, according to the National Water Commission, and the US hurricane center warned of dangerous storm surges along the coast, as well as 10 to 15 centimeters of rain.
