‚ÄúThis could be Canada’s version of (the hurricane). SandyCanadian Hurricane Center meteorologist Chris Fogarty said, pointing to Fiona’s size and intensity and her combination of hurricane and winter storm characteristics. Hurricane Sandy affected 24 states and all of the Eastern Seaboard, causing an estimated $78.7 billion in damages. loss

Fiona was about 1,200 miles southwest of Halifax, Nova Scotia, on Thursday morning, but the area is already bracing for a rare and historic impact.

“Please take this seriously because we are seeing climate numbers in our weather maps that are rarely seen here,” Fogarty said.

The lowest pressure ever recorded in Canada was 940 millibars in Newfoundland in January 1977, said Brian Tang, professor of atmospheric science at the University at Albany. “Current weather forecast models are indicating that Fiona will make landfall in eastern Nova Scotia with a pressure of 925 to 935 millibars, which would easily set a new record,” he said.

A pressure of 920 to 944 millibars is typically found in a Category 4 hurricane.

Many forecasters, including Fogarty, are comparing the storm to 2003. Hurricane Juan, which devastated the Canadian coast as a Category 2 storm.

“That storm was so small. This is so big,” Fogarty said.

A storm’s hurricane-force winds extend 70 miles in either direction from its center.

— and tropical storm-force winds extending more than 200 miles. This means that a 140-mile-wide path can experience hurricane-force winds and an area over 400 miles can experience tropical-storm-force winds.

And according to Tang, Fiona could grow even stronger by the time the storm reaches Canada.

Effects of Fiona

Fiona is expected to reach Atlantic Canada on Friday evening, but the region will begin to experience deteriorating conditions early Friday.

Fiona is purely a hurricane right now. As it begins to interact with a cold weather system and the jet stream, it will evolve into a superstorm characterized by a strong tropical storm and a strong autumn storm with hurricane-force winds, very strong. It will rain. , and large storm surges and surges,” Tang explained.

The National Hurricane Center is predicting the storm will “continue with hurricane-force winds as it crosses Nova Scotia and enters the Gulf of St. Lawrence.” In fact, the storm could still pack winds of 100 mph when it hits the coast.

Nova Scotia, Prince Edward Island and western Newfoundland could get up to 6 inches of rain, with some areas getting up to 10 inches. This can result in significant flooding.

“We want people to take this very seriously and be prepared for extended periods of utility outages and structural damage to buildings,” Fogarty explained.

Deadly storms and large waves are predicted for the region.

Some waves on the eastern side of the Gulf of St. Lawrence could exceed 39 feet, and the western Gulf will see waves up to 26 feet from the north, which will likely cause significant erosion on beaches north of Prince. Edward Island, Canada’s hurricane center said.

The hurricane center also warns of coastal flooding, especially during high tide.

It has been almost 50 years since the storm hit Nova Scotia and Cape Breton. Those were both winter storms — in 1974 and 1976, Fogarty said. Many people won’t even remember those two storms, so forecasters are trying to send a clear message to residents to be prepared.
