MEXICO CITY — Tropical Storm Norbert strengthened well off Mexico’s southern Pacific coast Sunday and threatened to become a hurricane in 24 hours, the U.S. National Hurricane Center said.
Norbert formed overnight and was centered 250 miles south of Zihuatanejo, a resort town north of Acapulco.
It had winds of 60 mph.
The storm could become a hurricane by Monday. But its northwestern path was taking it farther from land, said Jamie Rhome, a hurricane specialist with the Miami-based center.
There were only sporadic rains in Guerrero state, home to Acapulco and Zihuatanejo, where local elections took place as planned.
Norbert was projected to pass southwest of the Baja California Peninsula on Friday, but Rhome said it was to early to tell whether it would head for land.
Tropical Storm Marie, meanwhile, lingered 875 miles southwest of the southern tip of Baja California, posing no threat to land.
