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 Authority of Electric Energy and LUMA Energy, which operates Puerto Rico’s power grid, continue to work on the island-wide power outage that is impacting nearly 1.5 million customers, according to Pierluisi.
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.
But officials have stressed it won’t be like last time: Not long before the lights went out, Abner Gomez, head of public safety and crisis management at LUMA Energy, said utility authorities plan to repair and restore electricity with the help of local government agencies. “This is not Maria, this hurricane will not be Maria,” Gomez said.
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.
“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.”
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.
The northern and eastern Dominican Republic, too, is forecast to see 4 to 8 inches of rain, with isolated totals up to 12 inches possible.
“These rains will produce life-threatening flash flooding and urban flooding across Puerto Rico and the eastern Dominican Republic, along with mudslides and landslides in areas of higher terrain,” the hurricane center said.
Puerto Rico officials continue to closely watch the island’s mountain regions, which have suffered landslides in the past and where the soil is saturated from the rain, Pierluisi said.
Around 120 shelters with 25,000 cots have been opened for those in need, the governor said. Classes Monday have been canceled and government workers — save emergency workers — should stay home, too.
A hurricane warning — indicating hurricane conditions are expected — was issued for Puerto Rico, including the islands of Vieques and Culebra, and later expanded to include the eastern Dominican Republic from Cabo Caucedo to Cabo Frances Viejo. The Dominican Republic’s northern coast, from Cabo Frances Viejo west to Puerto Plata, were under a hurricane watch Sunday morning, meaning hurricane conditions are possible in the next 48 hours.
President Joe Biden on Sunday morning approved an emergency declaration for Puerto Rico, freeing up federal resources, including the Federal Emergency Management Agency, for emergency response and disaster relief efforts.
The threat won’t end once the storm passes between Puerto Rico and the Dominican Republic. Further strengthening is expected, and the official forecast track indicates Fiona could be a major hurricane by Wednesday as it tracks to the east of the Bahamas and toward Bermuda.
“It appears likely that Fiona will become the first major hurricane of this Atlantic season in a few days,” the hurricane center said.
