Cabo San Lucas, Mexico ? Hurricane Otis weakened to a tropical storm Sunday and headed north toward an unpopulated stretch of the Baja California Peninsula, while another tropical storm crossed the Yucatan peninsula, apparently heading for open Gulf waters.

No immediate reports of damages or injuries were received in connection with either Otis or Tropical Storm Stan, officials in the states of Baja California Sur and Quintana Roo said.

Otis, once a Category One hurricane, had wind speeds of about 45 mph by Sunday and was expected to weaken and fall below tropical storm strength, according to the U.S. National Hurricane Center.

The storm was swirling about 125 miles south of Cabo San Lazaro, near the tip of the Baja California peninsula, and could cross over a relatively unpopulated stretch of coast about 300 miles north of the resort of Cabo San Lucas today.

Meanwhile, Tropical Storm Stan formed before dawn Sunday and then plowed into a marshy stretch of land about 40 miles southwest of the resort Tulum. The storm could re-emerge into the Gulf of Mexico today, where it was projected to gather strength again.
