MEXICO CITY, Oct 21 (Reuters) - Hurricane Roslyn is expected to hit Mexico's Pacific coast at near major hurricane strength bringing dangerous storm surges and flooding, the U.S. National Hurricane Center (NHC) said, as authorities urged residents in some areas to move to safety.
Roslyn had strengthened into a Category 1 hurricane by late on Friday, the Miami-based forecaster said, as it approached resort towns in central Mexico.
Hurricane conditions are expected to reach the coast by late Saturday or early Sunday, it said.
"Winds are expected to first reach tropical storm strength by midday Saturday, making outside preparations difficult or dangerous," the NHC said.
The NHC expects Roslyn to bring a dangerous storm surge with "large, destructive waves" and "significant coastal flooding".
