LES CAYES, Haiti — The death toll from a 7.2-magnitude earthquake in Haiti climbed to 1,297 on Sunday, a day after the powerful temblor turned thousands of structures into rubble and set off franctic rescue efforts ahead of a potential deluge from an approaching tropical storm.

Saturday’s earthquake also left at least 5,700 people injured in the Caribbean nation, with thousands more displaced from their destroyed or damaged homes. Survivors in some areas were forced to wait out in the open amid oppressive heat for help from overloaded hospitals.

Yet the devastation could soon worsen with the coming of Tropical Depression Grace, which is predicted to reach Haiti on Monday night. The U.S. National Hurricane Center demoted the tropical storm to a depression Sunday, but forecasters warned that regardless, Grace still posed a threat to bring heavy rain, flooding and landslides.

The earthquake struck the southwestern part of the hemisphere’s poorest nation, almost razing some towns and triggering landslides that hampered rescue efforts in a country already grappling with the coronavirus pandemic, a presidential assassination and a wave of gang violence.

The epicenter was about 78 miles west of the capital of Port-au-Prince, the U.S. Geological Survey said, and aftershocks continued to jolt the area Sunday.
