TOA BAJA, Puerto Rico (AP) 鈥� Ernesto strengthened into a hurricane Wednesday as it dropped torrential rain on and left nearly half of all customers in the U.S. territory without power as it threatened to become a major storm en route to .
The storm was located about 720 miles (1,160 kilometers) south-southwest of Bermuda and was moving over open waters. It had maximum sustained winds of 80 mph (130 kph) and was moving northwest at 16 mph (26 kph).
A hurricane watch was issued for Bermuda, while tropical storm warnings were discontinued for Puerto Rico and its outlying islands of Vieques and Culebra and for the U.S. and British Virgin Islands.
鈥淚 know it was a long night listening to that wind howl,鈥� U.S. Virgin Islands Gov. Albert Bryan Jr. said in a news conference.
An island-wide blackout was reported in 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 remained closed in the U.S. and British 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. More than 140 flights were canceled to and from Puerto Rico.
鈥淎 lot of rain, a lot of rain,鈥� Culebra Mayor Edilberto Romero said in a phone interview. 鈥淲e have trees that have fallen on public roads. There are some roofs that are blown off.鈥�
Flash flood warnings remained Wednesday afternoon because of ongoing rains.
In the north coastal town of Toa Baja, which is prone to flooding, dozens of residents moved their cars to higher areas.
鈥淓veryone is worried,鈥� said V铆ctor B谩ez as he sipped beer with friends and watched the rain fall. He only briefly celebrated that he had power. 鈥淚t's going to go out again.鈥�
Ernesto is forecast to move through open waters for the rest of the week and strengthen into a major hurricane. Its center is expected to pass near Bermuda on Saturday
鈥淩esidents need to prepare now before conditions worsen,鈥� said Bermuda's National Security Minister Michael Weeks. 鈥淣ow is not the time for complacency.鈥�
Forecasters also warned of heavy swells along the U.S. East Coast.
鈥淭hat means that anybody who goes to the beach, even if the weather is beautiful and nice, it could be dangerous 鈥� with those rip currents,鈥� said Robbie Berg, warning coordination meteorologist with the .
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.
Late on Tuesday, the U.S. Federal Emergency Management Agency had warned people in both U.S. territories to prepare for 鈥渆xtended power outages.鈥�
More than 640,000 customers were without power in Puerto Rico, along with 23 hospitals operating on generators, Gov. Pedro Pierluisi said Wednesday. He added that crews are assessing damage and that it was too early to tell when electricity would be restored.
鈥淲e are trying to get the system up and running as soon as we can,鈥� said Juan Saca, president of Luma Energy, the company that operates transmission and distribution of power in Puerto Rico.
Luma Energy said earlier Wednesday that its priority was to restore power to hospitals, the island鈥檚 water and sewer company and other essential services. More than 300,000 customers were without water as a result of power outages, Pierluisi said.
Puerto Rico鈥檚 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.
鈥淚t鈥檚 just frustrating that this many years later, we continue to see something like a storm cause such widespread outages in Puerto Rico, particularly given the risk that these outages can cause for vulnerable households in Puerto Rico,鈥� said Charlotte Gossett Navarro, the Hispanic Federation鈥檚 chief director for Puerto Rico.
Not everyone can afford generators on the island of 3.2 million people with a more than 40% poverty rate.
鈥淧eople already prepared themselves with candles,鈥� said Luc铆a Rodr铆guez, a 31-year-old street vendor.
Rooftop solar systems are scarce but keep growing in Puerto Rico, where fossil fuels generate 94% of the island's electricity. At the time Mar铆a hit, there were 8,000 rooftop installations, compared with more than 117,000 currently, according to the Institute for Energy Economics and Financial Analysis.
Ernesto is the fifth named storm and the third hurricane of this year鈥檚 Atlantic hurricane season. Since 1966, only four other years have had three or more hurricanes in the Atlantic by mid-August, according to Philip Klotzbach, Colorado State University hurricane researcher.
The National Oceanic and Atmospheric Administration has predicted an above-average Atlantic hurricane season this year . It forecast 17 to 25 named storms, with four to seven major hurricanes.
