Tropical Storm Grace heads toward quake-ravaged Haiti.

As people in Haiti desperately search for survivors from a devastating earthquake, the threat of yet another natural disaster looms over the island.

Tropical Storm Grace is projected to pass over Haiti on Monday, the National Hurricane Center said. A tropical storm watch has been issued, and the center advised people on the island to monitor the path of the storm, which could dump heavy rain and bring high winds to Haiti.

Robbie Berg, a hurricane specialist at the center, said on Saturday that the earthquake could increase the chance of mudslides.

“It could have shifted some of the ground and soil, which could make mudslides more common,” he said.

The storm was skirting Puerto Rico on Sunday and on a path to go directly over the Dominican Republic, Haiti and then Cuba before heading north toward the Gulf Coast of the United States.

The storm formed in the eastern Caribbean on Saturday morning, as the earthquake rocked Haiti’s western peninsula. It is the seventh named storm of the 2021 Atlantic hurricane season and follows several days of floods and power outages unleashed this week by Tropical Storm Fred, which weakened to a tropical depression.
