Mexico ? Hurricane Ivo picked up some speed late Thursday as it curved toward Mexico’s Pacific coast on a path that could take it near Baja Califorina’s resorts over the weekend, the U.S. National Hurricane Center said.

The storm, which was upgraded late Wednesday to a Category 1 hurricane, had sustained winds of about 70 mph, with gusts of 85 mph, on Thursday night. It was forecast to take a turn toward Baja.

The Hurricane Center said Ivo was likely to weaken into a tropical storm before hitting land Sunday. But it warned that any prediction of what its intensity would be over the weekend was “highly uncertain” and urged people in the peninsula to closely monitor Ivo.
