Hurricane Ernesto turns its attention to Bermuda, will churn up dangerous beach conditions for East Coast
The Category 1 hurricane will intensify and could become the season’s second major hurricane — Category 3 or stronger — as it crosses 600 miles of the Atlantic before reaching Bermuda early Saturday. A hurricane warning is in effect for the island.
Ernesto’s robust strengthening will be fueled by the extremely warm waters of the Atlantic – a phenomenon that’s becoming more frequent in a world warming due to fossil fuel pollution. The second major hurricane typically doesn’t arrive in an average season until mid-September, if it happens at all.
The center of the hurricane will track near or over Bermuda on Saturday but powerful wind gusts and heavy rain will arrive earlier. Drenching rain and tropical storm-force wind gusts could begin as early as Friday morning over the tiny island, which is about a third of the size of Washington, DC.
More powerful winds and torrential rainfall will likely arrive late Friday or early Saturday. Ernesto could unload 4 to 8 inches of rain over the island through Saturday night, with potential for isolated totals to approach a foot.
“This may result in considerable life-threatening flash flooding,” the National Hurricane Center warned Thursday.
Dangerous storm surge and significant coastal flooding will also unfold as Ernesto makes its closest approach to the island Saturday.
Dangerous surf for Eastern Seaboard
Ernesto will have wide-reaching impacts despite remaining so far from large land masses.
The hurricane will create massive waves — perhaps up to 40 feet high — in the open Atlantic that will spread hundreds of miles away. These elevated wave heights will bring rough seas and dangerous rip currents to the US East Coast, the Bahamas and parts of the Caribbean into early next week.
For a majority of the US Atlantic coast, the most dangerous coastal conditions will unfold over the weekend, coinciding with the time many people flock to the beach. Ernesto “will result in very dangerous rip currents (Saturday and Sunday),” the National Weather Service in Mount Holly, New Jersey, warned Thursday.
Rip currents can exhaust even the strongest swimmers and turn deadly. At least 29 people have been killed in rip currents this year in the US and its territories, according to the National Weather Service.
Beyond Bermuda, Ernesto will pass close to Atlantic Canada early next week and potentially bring some rain, wind and rough seas.
Outages linger after Ernesto
Ernesto’s center never made landfall over Puerto Rico or the US Virgin Islands but the system’s strong winds still knocked out power to hundreds of thousands of people in total.
In Puerto Rico, about half of all customers on the island were at one point without power Wednesday, according to LUMA Energy,the private company that operates the transmission and distribution of power in Puerto Rico. By Thursday morning, more than 400,000 were still in the dark.
In the US Virgin Islands, about 29,000 customers were without power Thursday morning, about half of the island’s tracked customers, according to PowerOutage.us.
Heavy rain soaked the Virgin Islands late Tuesday and Wednesday. More than half a foot of rain drenched much of Puerto Rico and caused widespread flash flooding. Some locations recorded nearly a foot of rain from Ernesto: Just over 10 inches of rain fell over a 24-hour period in the mountain town of Barranquitas, according to a preliminary weather service report, while Villalba saw around 9.5 inches.
A vehicle drives through a flooded roadway in Dorado, Puerto Rico, in the aftermath of Ernesto late Wednesday afternoon.
Intense rainfall and flooding caused several rivers to overflow their banks in Puerto Rico and interrupted water filtration processes at a number of water processing plants to varying degrees, according to the island’s water authority.
Even as Ernesto moved a few hundred miles away from Puerto Rico Wednesday night, water issues worsened. More than 300,000water customers – about 23% of total customers – were without drinking water Thursday morning, according to the island’s emergency portal system.
The weather conditions during Ernesto's approach will be influenced by the ongoing issue of fossil fuel pollution, leading to more frequent instances of extremely warm Atlantic waters. Despite Ernesto not making landfall, the hurricane will generate dangerous rip currents on the US East Coast, posing a risk to swimmers.
