Hurricane Ernesto churned towards Bermuda on Friday as a Category 2 storm packing powerful winds and likely to produce life-threatening flooding and storm surges in the British island territory.
Ernesto, centred about 205km south-southwest of the archipelago at 5pm Atlantic Standard Time, was producing sustained winds of up to 155km/h and had the potential to drop up to 230mm of rain, the US National Hurricane Center said.
The centre of Ernesto was expected to pass near or over Bermuda on Saturday morning, making conditions ripe for storm surges and flash flooding by the afternoon.
"Folks, be under no illusion. This storm is the real deal," said Michael Weeks, Bermuda's national security minister, at a press conference on Friday.
He warned Bermudians to brace for 36 hours of hurricane and tropical storm-force winds starting Friday afternoon.
Warren Darrell, 52, of Smith's Parish, said he had stocked up on groceries for his family, battened down the hatches and removed furniture from the lawn in preparation for Ernesto's arrival.
"I'm ready to play games with my daughters and wait," he said. "I'm a bit worried, a little bit worried, but I think we'll overcome. I think we'll be fine."
Winds, torrential rains and rip currents began picking up just before noon at John Smith's Bay on Bermuda's Main Island. The government planned to close a causeway bridge linking it to St. George's Island on Friday night. A number of tourists and locals were seen roaming around the south shore, while a person was windsurfing as waves grew in size before 2pm.
Ernesto was crawling at roughly 20km/h on a north-northeast trek, the Miami-based hurricane centre said.
Bermuda, a collection of 181 small islands clustered more than 965 km off the Carolina coast, could expect hurricane conditions to persist until Sunday, National Hurricane Center Director Michael Brennan said in an online briefing.
Fewer than a dozen hurricanes have made direct landfall on Bermuda, according to records dating to the 1850s.
Puerto Rico power outages
Earlier this week, Ernesto grazed Puerto Rico as a tropical storm, bringing heavy rainfall to the US Caribbean territory and cutting power to about half of its 1.5 million customers.
About 250,000 homes and businesses remained without power as of Friday morning, according to LUMA Energy, the island's main electricity distributor.
Puerto Rico's power grid was notoriously fragile. The island has experienced prolonged power outages in recent years when weather systems much more powerful than Ernesto rolled through.
Since Hurricane Irma seven years ago, Puerto Rico's grid has been in a rebuilding process, and residents have increased their use of renewable power, according to a study by the Institute for Energy Economics and Financial Analysis.
Despite work to shore up the grid, and US$1 billion in federal funding, the island's main power organisations have failed to balance budgets or stabilise the central power network, said Tom Sanzillo, the institute's director of finance.
"The grid in Puerto Rico remains in a state of disrepair," he said.
Ernesto is the fifth named Atlantic storm of what is expected to be an intense hurricane season.
Slow-moving Debby hit Florida's Gulf Coast as a Category 1 hurricane just last week before soaking some parts of the Carolinas with up to 60cm of rain.
