Hurricane Fiona kicks up massive waves of about 50 feet as Bermuda, Canada brace for impacts

Hurricane Fiona is kicking up massive waves as it approaches Bermuda, where weather conditions are expected to deteriorate Friday as the storm heads toward Atlantic Canada.

Fiona's march north comes after the storm devastated Puerto Rico and other Caribbean islands, where many residents are still left without power and water days after Fiona hit.

Waves of about 50 feet were reported by the National Oceanic and Atmospheric Administration as a Saildrone sailed in the Atlantic on Thursday.

A hurricane warning is in effect for Bermuda as Fiona, a Category 4 hurricane, approaches, according to the National Hurricane Center. Hurricane conditions are expected in Bermuda starting Thursday night through Friday morning, causing elevated coastal water levels, potential power outages and about two to four inches of rainfall, the center said.

Fiona is also expected to bring "life-threatening surf and rip current conditions" to the northeast U.S. coast, the center said.

On Friday morning, Fiona was located less than 200 miles west-southwest of Bermuda with maximum sustained winds of 130 mph and was moving north-northeast at 21 mph, the center said. The storm is expected to pass to the west of the island Thursday night before approaching the Canadian province of Nova Scotia on Friday. By Saturday, it will be close to Nova Scotia and Newfoundland.

Hurricane Fiona takes aim at Atlantic Canada

While the storm is expected to weaken Friday, Fiona is still forecast to be "a large and powerful post-tropical cyclone with hurricane-force winds" when it hits Canada, according to the National Hurricane Center.

A hurricane watch has been issued for parts of Atlantic Canada, including Nova Scotia, Prince Edward Island, The Magdalen Islands, and the coast of Newfoundland, according to the center.

Those areas are expected to see three to six inches of rain with local maximums of up to 10 inches, causing potentially significant flooding, the center forecast.

Atlantic Canada is expected to "receive the full brunt of Hurricane Fiona's impacts this weekend" with some areas at risk for "extreme damage," AccuWeather said.

"Fiona will bring widespread power outages due to high winds, flooding due to torrential rain and isolated storm surge and massive seas offshore and in the Gulf of St. Lawrence," AccuWeather meteorologist Brett Anderson said.

Tropical system Invest 98L developing

A developing tropical system could spin up into a hurricane in the Gulf of Mexico by the middle of next week, forecasters warned Wednesday.

"This is the most significant threat for the U.S. mainland we've had this hurricane season," AccuWeather chief meteorologist Jonathan Porter said.

Most computer models predict the system, Invest 98L, will be a tropical storm by the weekend in the Caribbean. The models show the system strengthening into a hurricane by early next week. If it becomes a named storm, it would be called Hermine. Read more here.

Biden pledges to aid Puerto Rico as residents still without power, water

Days after Fiona hit Puerto Rico, about 62% of 1.47 million power customers remained without energy on Thursday, and a third of customers — more than 400,000 — were without water service.

President Joe Biden on Thursday said he is committing the full force of the federal government to help the island recover from Fiona.

"We’re with you. We’re not going to walk away," Biden said.

Puerto Rico’s Electric Energy Authority Director Josué Colón said areas less affected by Fiona should have power restored early Friday, but officials did not say when other areas would have power back.

More businesses, including grocery stores and gas stations, are temporarily closing as power outages drag on. Many residents are concerned about the availability of fuel and basic goods.

Gasoline was unavailable in Salinas after all gas stations shut down Wednesday, according to community leader Wanda Ríos Colorado.

Puerto Rico’s Department of Consumer Affairs said there is no shortage of fuel, but rather a disruption to the system as a result of flooding, landslides, and the island-wide power outage.

Some fuel stations were unable to reopen or could not be refilled in the storm’s early aftermath, officials said.

As much as 80% of Puerto Rico's crops were also destroyed by Fiona, including coffee crops that had just reached a successful harvesting peak post-Maria, according to the humanitarian non-governmental organization Mercy Corps.

Puerto Rico struggles to reach isolated areas

After destroying roads and bridges and causing mudslides, Fiona has left hundreds of Puerto Ricans stranded as authorities work with religious groups and nonprofits to reach areas isolated by the storm in order to provide vital food, water and medicine.

At least six municipalities have areas cut off by the storm, Nino Correa, commissioner for Puerto Rico’s emergency management agency, estimated.
