The remnants of Hurricane Eta unleashed torrential rains and catastrophic flooding on Central America, with fatalities sharply up on Thursday as streets turned into rivers and dozens more were feared to be buried in their homes by mudslides.

In Guatemala, the death toll shot up past 50 over the course of the day, according to President Alejandro Giammattei, who said mudslides around the town of San Cristobal Verapaz had swallowed about 25 homes.

“Right now, we’re trying to get there on foot because there’s no other way,” said Giammattei, referring to flooded out roads near the town, located about 120 miles (193 km) north of the Guatemalan capital.

In neighboring Honduras, families waded through flooded streets of the northern city of San Pedro Sula, while cars sat almost submerged in parts of the central Guatemalan city of San Pedro Carcha, television footage and images posted on social media showed.

Hundreds of people were left stranded on roofs in Honduras as frantic rescue efforts played out, which were credited with taking around 500 people to safety.

“The situation is serious, it’s shocking and needs to be dealt with professionally, fast,” Honduran President Juan Orlando Hernandez told HCH television earlier in the day.

Damage and destruction had spread across the “vast majority” of Honduras and speedboats and helicopters would be sent to rescue people in inaccessible areas, Hernandez added.

One of the fiercest storms to hit Central America in years, Eta struck Nicaragua as a Category 4 hurricane on Tuesday with winds of 150 miles per hour (241 kph) before weakening to a tropical depression as it moved inland and into neighboring Honduras.

By Thursday, authorities confirmed seven deaths in Honduras. Media in Nicaragua also reported two miners had died in a mudslide.

Guatemala’s disaster relief agency Conred had earlier said about 15 homes were likely covered by mudslides, possibly affecting around 75 people.

Giammattei had already declared a state of emergency in nearly half of the country’s 22 departments.

In both Guatemala and Panama, several people have been reported missing as water levels continue to rise.

In southern Costa Rica, a landslide killed two people in a house, a Costa Rican woman and an American man, officials said. Meanwhile, five people, including three children, died in flooding in Panama’s Chiriqui province, near the Costa Rica border, authorities said.

There was better news in Honduras, where 60 fishermen who disappeared at sea on Tuesday returned after taking shelter on cays until they were rescued, said community leader Robin Morales.

Calling their survival a “miracle,” Morales said a man among them presumed dead from a heart attack also made it back.

“Our friends are alive, thank God,” he said.

Across swaths of Nicaragua, Honduras, Guatemala and Costa Rica, high winds and heavy rain have damaged homes, roads and bridges, forcing thousands to take cover in shelters.

Eta was moving northwest through Honduras toward the Caribbean, at eight miles per hour (13 kph) on Thursday, the U.S. National Hurricane Center (NHC) said. Heavy rains continued and the storm’s top winds edged up to 35 mph (56 kph).

One unidentified woman made a desperate plea for help on Honduran television from La Lima, a municipality southeast of San Pedro Sula.

“I’ve got five children on the roof of my house and nobody’s helping me to get them down,” she said.

Eta is forecast to return to sea and regain momentum as a tropical storm, possibly reaching the Cayman Islands, Cuba and southern Florida in the coming days, the NHC said.
