Pallade Veneta - Strengthening Hurricane Fiona heads north off Turks and Caicos

The US National Hurricane Center (NHC) said Tuesday evening that the storm had moved 75 miles north of Turks and Caicos, though it was still producing strong winds and heavy rains on portions of the British territory that is home to some 38,000 people.

NHC aircraft had also measured an uptick in Fiona's maximum windspeeds, now at 125 miles (205 kilometers) per hour, making it a major hurricane.

At least five people have died as the storm churned across the Caribbean -- one in the French overseas department of Guadeloupe and two each in Puerto Rico and the Dominican Republic.

After leaving the Turks and Caicos Islands, home to some 38,000 people, Fiona began a slow crawl northwards on a path that could see the strengthening storm approach Bermuda late Thursday.

"Hurricane Fiona has proven to be an unpredictable storm," Anya Williams, the deputy governor of Turks and Caicos, said in a broadcast.

Williams said no casualties or serious injuries had been reported in Turks and Caicos, but she urged residents to continue to shelter in place.

Blackouts were reported on Grand Turk and several other islands in the archipelago and 165 people were admitted to shelters, she said, adding that Britain's Royal Navy and the US Coast Guard are standing by to provide assistance.

Dominican Republic President Luis Abinader has declared three eastern provinces to be disaster zones: La Altagracia -- home to the popular resort of Punta Cana -- El Seibo and Hato Mayor.

Authorities said Tuesday that more than 10,000 people had been moved to "safe areas," while some 400,000 are without electricity.

Footage from local media showed residents of the east coast town of Higuey waist-deep in water trying to salvage personal belongings.

"It came through at high speed," Vicente Lopez told AFP in Punta Cana, bemoaning the destroyed businesses in the area.

- 'I have food and water' -

US President Joe Biden has declared a state of emergency in Puerto Rico and dispatched the head of the Federal Emergency Management Agency to the island, which is still struggling to recover from Hurricane Maria five years ago.

"We’re sending hundreds of additional personnel to support all affected communities," FEMA Administrator Deanne Criswell said Tuesday after a tour with Pedro Pierluisi, the island's governor.

Pierluisi said the storm had caused catastrophic damage on the island of three million people since Sunday, with some areas receiving more than 30 inches (76 centimeters) of rain.

Michelle Carlo, medical advisor for Direct Relief in Puerto Rico, told CBS News that "a lot of people in Puerto Rico are suffering right now."

"About 80 percent of Puerto Ricans are still without power and about 65 percent are without water service," Carlo said.

Across Puerto Rico, Fiona caused landslides, blocked roads and toppled trees, power lines and bridges, Pierluisi said.

A man was killed as an indirect result of the power blackout -- burned to death while trying to fill his generator, according to authorities.

On Monday afternoon, Nelly Marrero made her way back to her home in Toa Baja, in the north of Puerto Rico, to clear out the mud that surged inside after she evacuated.

"Thanks to God, I have food and water," Marrero -- who lost everything when Hurricane Maria devastated Puerto Rico -- told AFP by telephone.

The hurricane has left around 800,000 people without drinking water as a result of power outages and flooded rivers, officials said.

After years of financial woes and recession, Puerto Rico in 2017 declared the largest bankruptcy ever by a local US administration.

The grid was privatized in June 2021 in an effort to resolve the problem of blackouts, but the issue has persisted, and the entire island lost power earlier this year.
