Power gas gone out across all of the US territory of Puerto Rico on Sunday, according to PowerOutage.us, as Hurricane Fiona bears down on the islands, which are already grappling with the threat of flooding and mudslides stemming from the Category 1 storm.
“Puerto Rico is 100% without power due to a transmission grid failure from Hurricane Fiona,” the website said.
Gov. Pedro Pierluisi confirmed the outage in a tweet, noting the entire electric system was out of service and officials have activated the proper protocols to work to restore power.
The blackout — which followed hours of progressively worsening power outages — comes five years after Puerto Rico’s power grid was devastated by Hurricane Maria in September 2017, leaving many residents without electricity for months.

Fiona has strengthened into a Category 1 hurricane, with sustained winds of 80 mph and gusts of up to 100 mph as it churns in the Caribbean about 50 miles south of Puerto Rico, bringing with it the threats of flooding and mudslides, according to the National Hurricane Center’s latest update.
The storm’s impacts have already been felt: At least one death has been reported in Basse-Terre in the French territory of Guadeloupe, according to the vice president of the territory’s environmental agency, who said the capital had been devastated by flooding. And in Puerto Rico, nearly 570,000 customers — or 40% of the island’s total — were without power as of 12:30 p.m. ET Sunday, according to PowerOutage.us. And the flash flooding has already begun.
Puerto Rico Gov. Pedro Pierluisi warned the storm “will cover our entire island” in a news conference Sunday, noting winds and rain bands from the storm may extend outward up to 100 to 120 miles. “This is impacting us now,” Pierluisi said. “It’s south of Puerto Rico but very close to our coast.”
The hurricane — the third of the 2022 Atlantic Hurricane Season — is bearing down on Puerto Rico, with the eyewall approaching the southern coast, according to the National Weather Service’s office in San Juan. Winds are expected to increase along the immediate coastline, the hurricane center said, while conditions are forecast to deteriorate throughout Sunday afternoon and evening as Fiona moves near or over the southwestern part of Puerto Rico.

There is a possibility Fiona’s center might skirt Puerto Rico, precluding a traditional “landfall.” But regardless, the impacts of the storm remain the same.
“Additional strengthening is forecast during the next 48 hours while Fiona moves near Puerto Rico, the Dominican Republic and over the southwestern Atlantic,” the hurricane center said. “Hurricane conditions are expected on Puerto Rico today, and are expected in portions of the eastern Dominican Republic tonight and Monday.”
The National Weather Service on Sunday warned of life-threatening to catastrophic flooding, issuing flash flood warnings for south and east Puerto Rico, including Ponce and Yabucoa, through at least mid-afternoon. The service said flooding had started after an estimated 1 to 4 inches of rain had already fallen.
Very heavy rainfall of 12 to 16 inches is forecast across a wide swath of Puerto Rico, with most of the rain expected Sunday, and isolated locations across southern and eastern Puerto Rico could see up to 25 inches, per the hurricane center.
