As Hurricane Fiona continues to churn toward Bermuda, weather conditions are expected to deteriorate on the island Thursday before 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.
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.
Thursday morning, Fiona was located 455 miles southwest of Bermuda with maximum sustained winds of 130 mph and was moving north-northeast at 13 mph, the center said. The storm is expected to pass just to the west of the island Thursday night before approaching the Canadian province of Nova Scotia on Friday.
After Hurricane Maria: Puerto Ricans were still struggling with Hurricane Maria's devastation. Then came Hurricane Fiona.
The aftermath: Many Puerto Ricans remain without power, water and medical supplies after Hurricane Fiona battered the island. Here's what the devastation looks like.
Recovery begins: Puerto Ricans describe the 'nightmare' of weathering Fiona just five years after Hurricane Maria. Here's what recovery efforts look like.
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.
Novia Scotia, Prince Edward Island and western Newfoundland 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.

Many Puerto Ricans remain without water, food, medicine
Days after Fiona hit Puerto Rico, more than a million people remained without power Wednesday, said Keith Turi, FEMA assistant administrator for recovery. And the Puerto Rico Aqueduct and Sewer Authority said about 45% of its subscribers were still without water service.
More than 1,000 people were in shelters early Wednesday, said Brad Kieserman, vice president of operations and logistics for the Red Cross.
Some health care centers were running on generators, and one cancer hospital had to transfer patients because of power issues, said Alexandra Lúgaro, 41, executive director of the non-profit Foundation for Puerto Rico's Center for Strategic Innovation and a former candidate for governor.

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.
