Carlotta weakened from a hurricane to a tropical storm Saturday over southern Mexico after pummeling the country's Pacific coast with strong winds and heavy rains and causing a mudslide that killed two children.

The U.S. National Hurricane Center said a tropical storm warning was in effect west of Punta Maldonado to the resort city of Acapulco.

The storm hit the southern Mexican coast on Friday as a hurricane, making landfall in the state of Oaxaca. Officials in Oaxaca's town of Pluma Hidalgo say two young girls died there when a mudslide struck their home.

The Hurricane Center says the center of Carlotta or its remnants will remain inland over southern Mexico for several days.

The storm is not expected to affect the G20 summit which begins Monday in Mexico. Leaders of the Group of 20 top economies are meeting in the Pacific coast resort of Los Cabos at the southern tip of Mexico's Baja California peninsula, far from the storm's path.
