Tropical Storm Fiona forms behind Hurricane Earl

MIAMI — The National Hurricane Center says Tropical Storm Fiona has formed in the Atlantic Ocean behind Hurricane Earl, which is battering the northeastern Caribbean.

Fiona formed east of the Leeward Islands on Monday afternoon and forecasters say a tropical storm watch may be required later in the day.

The storm has winds of 40 mph (65 kph) and is about 890 miles (1,435 km) east of the Leeward Islands.

Earl, meanwhile, rapidly intensified into a major Category 3 storm on a path projected to menace the United States.

SAN JUAN, Puerto Rico (AP) — Hurricane Earl battered tiny islands across the northeastern Caribbean with heavy rain and roof-ripping winds Monday, rapidly intensifying into a major Category 3 storm on a path projected to menace the United States.

Already dangerous with sustained winds of 125 mph (205 kph), Earl is expected to gain more strength before potentially brushing the U.S. East Coast this week and bringing deadly rip currents.

The U.S. National Hurricane Center in Miami warned coastal residents from North Carolina to Maine to watch the storm closely.

“Any small shift in the track could dramatically alter whether it makes landfall or whether it remains over the open ocean,” said Wallace Hogsett, a meteorologist at the center. “I can’t urge enough to just stay tuned.”

In the Caribbean, Earl caused flooding in low-lying areas and damaged homes on islands including Antigua and Barbuda, Anguilla and St. Maarten. Several countries and territories reported power outages. Cruise ships were diverted and flights canceled across the region.

“We are getting a battering with wind and rain,” said Martin Gussie, a police officer in Anguilla. Several utility poles were down and a couple of roofs had blown away, and it was still too dangerous to go out and assess the full extent of damage, he said.

The storm’s center passed just north of the British Virgin Islands on Monday afternoon. It was forecast to move gradually away from the Caribbean and approach the U.S. Mid-Atlantic region around Thursday, before curving back out to sea, potentially swiping New England or far-eastern Canada.

The Hurricane Center said it was too early to say what effect Earl would have in the U.S., but warned it could at least kick up dangerous rip currents. A surfer died in Florida and a Maryland swimmer has been missing since Saturday in waves spawned by former Hurricane Danielle, which weakened to a tropical storm Monday far out in the north Atlantic.

Craig Fugate, administrator of the Federal Emergency Management Agency, said Earl’s approach ought to serve as a reminder for Atlantic coastal states to update their evacuation plans.

“It wouldn’t take much to have the storm come ashore somewhere on the coast,” Fugate said. “The message is for everyone to pay attention.”

The rapid development of Earl, which only became a hurricane Sunday, took some islanders and tourists by surprise.

Wind was already rattling the walls of Lila Elly Ali’s wooden house in Anegada, the northernmost of the British Virgin Islands, when she and her son went out to nail the doors shut Monday.

“They say the eye of the storm is supposed to come close to us, so we’ve just got to pray. Everyone here is keeping in touch, listening to the radio,” the 58-year-old said by phone from the island of 280 people.

At El Conquistador Resort in Fajardo, Puerto Rico, people lined up at the reception desk, the lights occasionally flickering, to check out and head to the airport. There, more delays awaited.

John and Linda Helton of Boulder, Colorado, opted to ride out the storm. The couple, celebrating their 41st wedding anniversary, finished a cruise Sunday and planned to spend three days in Puerto Rico.

“There was a huge line of people checking out as we were coming in, and I thought it was just that summer vacation must be over,” said John Helton, a real estate appraiser. “But we paid for the room, so we might as well stick it out.”

“I don’t think we could get a flight even if we wanted to leave,” Linda Helton added.

There were no reports so far of major damage from Earl.

In St. Maarten, sand and debris littered the streets, and winds knocked down trees and electricity poles and damaged roofs. But police spokesman Ricardo Henson said there was no extensive damage to property.

Alisha Daya, a 24-year-old tourist from Milwaukee, wore earplugs but still had trouble sleeping overnight because of the wind and crashing waves at the Oyster Bay Beach Resort.

“It was loud because we were right on the ocean,” Daya said, adding that the storm delayed their planned departure Monday but the worst seemed to be over.

In Antigua, at least one home was destroyed but there were no reports of serious injuries.

Jeremy Collymoore, head of the Barbados-based Caribbean Disaster Emergency Response Agency, said islands such as Antigua and Anguilla appeared to have been spared worse damage because they were raked by the system’s northwestern quadrant — the most forgiving part.

Mudslides and flooding were still a risk, with 4 to 8 inches (10 to 20 centimeters) of rain forecast to fall on islands including Puerto Rico.

The U.S. Virgin Islands imposed a curfew for Monday night.

Monday afternoon, Earl was about 60 miles (100 kilometers) northeast of St. Thomas in the U.S. Virgin Islands and headed west-northwest at 15 mph (24 kph), according to the center in Miami. Hurricane-force winds extended outward up to 60 miles (95 kilometers) from its center.
