SANTO DOMINGO, Dominican Republic (AP) — Tropical Storm Franklin roared toward the island of Hispaniola shared by the Dominican Republic and Haiti early Wednesday amid fears it would trigger deadly landslides and heavy flooding in both countries.

Franklin was expected to swirl above the island for most of Wednesday, with forecasters warning the storm could dump up to 10 inches (25 centimeters) of rain, with a maximum of 15 inches (38 centimeters) in isolated areas.

By Tuesday night, the storm was located 175 miles (280 kilometers) southwest of Santo Domingo, the capital of the Dominican Republic, according to the National Hurricane Center in Miami. It had maximum winds of 40 mph (65 kph) and was moving northward at 9 mph (15 kph).

Meanwhile, Tropical Storm Harold weakened into a tropical depression Tuesday night after making landfall in South Texas, bringing strong winds, rain and leaving thousands of homes without power.

In the Caribbean, officials were most concerned about the storm’s impact in Haiti, which is vulnerable to catastrophic flooding given the country’s severe erosion.

Ariel Henry, the country’s prime minister, had urged Haitians on Tuesday to stock up on water, food and medication as authorities checked on some of the more than 200,000 people displaced by gang violence, with some living on the street or in makeshift shelters.

Some recalled how a powerful thunderstorm that unleashed heavy rains one day in June left more than 40 people dead across Haiti.

In the Dominican Republic, officials shuttered schools, government agencies and several airports with at least 24 of the country’s 31 provinces under red alert.

Flooding already was reported on Tuesday in the capital of Santo Domingo and beyond, where residents prepared for heavy rainfall.

“We’re scared of the river,” said Doralisa Sánchez, a government employee who lives near the Ozama River that divides the capital and has had to flee her home three times during previous storms.

She hoped Franklin wouldn’t force her to seek shelter and temporarily abandon her home because she said people steal belongings left behind.

Others, like businesswoman Albita Achangel, worried they had nowhere to go if the waters start rising.

“We are hoping for God’s will,” she said, adding that her patio already was flooded.

The storm worried thousands of Dominicans who live in flood-prone areas.

“When two drops of water fall here, this suddenly becomes flooded,” said Juan Olivo Urbáez, who owns a small business in a community near the Ozama River.

A tropical storm warning was in effect for the entire southern coast of the Dominican Republic and Haiti, as well as the entire northern Dominican coast. A tropical storm watch was posted for the Turks and Caicos Islands.

Franklin is the seventh named storm of the Atlantic hurricane season, which runs from June 1 to Nov. 30. An eighth named storm, Gert, dissipated on Tuesday.

On Aug. 10, the National Ocean and Atmospheric Administration updated its forecast and warned that this year’s hurricane season would be above normal. Between 14 to 21 named storms are forecast. Of those, six to 11 could become hurricanes, with two to five of them possibly becoming major hurricanes.

Harold made landfall Tuesday morning as a tropical storm, near South Padre Island, on the Texas Gulf coast, leaving thousands of homes and businesses in the city of Corpus Christi without power. By Tuesday night, the National Hurricane Center reported that it had become a depression.
