Ernesto has intensified into a hurricane and is on a path toward Bermuda, forecasters say

SAN JUAN, Puerto Rico (AP) — Ernesto intensified Wednesday into a hurricane over the Caribbean and is on a path toward Bermuda, forecasters said.

The storm had maximum sustained winds of 120 kph (75 mph), making it a Category 1 hurricane, the National Hurricane Center said.

Before it was confirmed to strengthened to a hurricane, the tropical storm dropped torrential rain on eastern Puerto Rico and left hundreds of thousands of people without power in the U.S. territory.

Ernesto is forecast to move through open waters and make its closest approach to Bermuda on Saturday. It is expected to become a major Category 3 storm, with forecasters warning of heavy swells along the U.S. East Coast.

THIS IS A BREAKING NEWS UPDATE. THE FOLLOWING IS AP’S PREVIOUS STORY.

Tropical Storm Ernesto dropped torrential rain on Puerto Rico on Wednesday and left nearly half of all clients in the U.S. territory without power as it threatened to strengthen into a major hurricane en route to Bermuda.

The storm was located about 125 miles (200 kilometers) northwest of San Juan, Puerto Rico and was moving over open waters. It had maximum sustained winds of 70 mph (110 kph) and was moving northwest at 16 mph (26 kph).

Ernesto was expected to become a hurricane later Wednesday. “While it is possible Ernesto is already a hurricane, radar data does not yet support an upgrade,” the National Hurricane Center in Miami said.

A tropical storm warning was in effect for Puerto Rico and its outlying islands of Vieques and Culebra and for the U.S. and British Virgin Islands.

“I know it was a long night listening to that wind howl,” U.S. Virgin Islands Gov. Albert Bryan Jr. said in a news conference.

An island-wide blackout was reported in St. John and St. Croix, and at least six cell phone towers were knocked offline across the U.S. territory, said Daryl Jaschen, emergency management director.

He added that the airports in St. Croix and St. Thomas were expected to reopen at midday.

Schools and government agencies, however, remained closed in the U.S. Virgin Islands and Puerto Rico, where heavy flooding was reported in several areas, forcing officials to block roads, some of which were strewn with trees. Nearly 100 flights also were canceled to and from Puerto Rico.

“A lot of rain, a lot of rain,” Culebra Mayor Edilberto Romero said in a phone interview. “We have trees that have fallen on public roads. There are some roofs that are blown off.”

Ernesto is forecast to move through open waters for the rest of the week and make its closest approach to Bermuda on Saturday. It is expected to become a major Category 3 storm in the upcoming days and then weaken slightly to a Category 2 as it nears Bermuda.

“Residents need to prepare now before conditions worsen,” said Bermuda’s National Security Minister Michael Weeks. “Now is not the time for complacency.”

Forecasters also warned of heavy swells along the U.S. East Coast.

“That means that anybody who goes to the beach, even if the weather is beautiful and nice, it could be dangerous … with those rip currents,” said Robbie Berg, warning coordination meteorologist with the National Hurricane Center.

Between 4 to 6 inches of rain is expected in the U.S. and British Virgin Islands and between 6 to 8 inches in Puerto Rico, with up to 10 inches in isolated areas.

The government of the U.S. Virgin Islands reported an island-wide blackout in St. Croix, while in Puerto Rico, more than half a million customers were without power.

Late on Tuesday, the U.S. Federal Emergency Management Agency had warned people in both U.S. territories to prepare for “extended power outages.”

Luma Energy, the company that operates transmission and distribution of power in Puerto Rico, said early Wednesday that its priority was to restore power to hospitals, the island’s water and sewer company and other essential services.

Puerto Rico’s power grid was razed by Hurricane Maria in September 2017 as a Category 4 storm, and it remains frail as crews continue to rebuild the system.

Not everyone can afford generators on the island of 3.2 million people with a more than 40% poverty rate.

“People already prepared themselves with candles,” said Lucía Rodríguez, a 31-year-old street vendor.

Puerto Rico Gov. Pedro Pierluisi announced late Tuesday that U.S. President Joe Biden had approved his request to use emergency FEMA funds as a result of the tropical storm.

Ernesto is the fifth named storm of this year’s Atlantic hurricane season.

The National Oceanic and Atmospheric Administration has predicted an above-average Atlantic hurricane season this year because of record warm ocean temperatures. It forecast 17 to 25 named storms, with four to seven major hurricanes of Category 3 or higher.
