Hurricane Fiona intensifies, alerts issued in Atlantic Canada

Kalin Mitchell with the latest on Hurricane Fiona CTV Atlantic Chief Meteorologist shares the latest information on Hurricane Fiona and its expected impact on the region.

Hurricane Fiona intensified rapidly from a Category 1 to a Category 3 hurricane as it moved towards the Turks and Caicos Islands Monday afternoon into Tuesday morning, with maximum sustained winds near the eye of 185 kilometres per hour.

TRACK

The hurricane is forecast to move north into an area of favourable ocean water temperatures and atmospheric conditions allowing it to become a Category 4 hurricane, with maximum sustained winds near 220 kilometres per hour as it passes west of Bermuda late Thursday. While a direct hit to Bermuda is not forecast, the Island is still being advised to monitor the progress of the hurricane.

The National Hurricane Center then brings Fiona as a Category 3 hurricane into the Scotia Slopes marine area south of Sable Island Friday night. Fiona is then forecast to approach eastern Nova Scotia as a Category 2 hurricane Saturday morning.

The forecast cone -- or the area the centre of the storm is expected to take a path through -- still encompasses a large area of Atlantic Canada, stretching from Halifax on the western side, to the Burin Peninsula in Newfoundland on the eastern side. The cone does not predict the entirety of the area to be impacted by the storm nor the intensity of those impacts.

POST-TROPICAL TRANSITION

Regardless of the approach intensity and track of the hurricane, it is expected to undergo a post-tropical transition as it passes through Atlantic Canada.

This starts as the hurricane interacts with a weather front (cold front) on Friday and continues into the weekend. There will be a number of changes to the storm as a result including:

ALERTS ISSUED

Environment Canada and the Canadian Hurricane Centre posted a Tropical Cyclone Information Statement for Newfoundland, Prince Edward Island, eastern New Brunswick, and all but the southwest of Nova Scotia Tuesday morning. They state that they are monitoring the hurricane, that the storm will become quite large and impact a broad area, and that the Canadian Hurricane Centre will begin six-hourly bulletin updates Tuesday night or early Wednesday.

THE MARITIMES

While this storm will be large with broad impacts, we still need to narrow down the approach it will take through the region. A move towards Newfoundland will lessen the intensity of the impacts for the Maritimes, while a pass near or through Cape Breton would increase them. That will be narrowed considerably over the next few days.

The National Hurricane Center is giving a moderate-to-high probability of eastern P.E.I. and eastern Nova Scotia getting into tropical storm force winds (one minute sustained wind of 63+ kilometres per hour, stronger gusts) Friday night into Saturday morning. That said, the entirety of the Maritimes should be checking in on the forecast for the storm daily.

Some initial preparation for a high wind, heavy rain event would be appropriate. Things like checking working condition of generators and sump pumps, and making sure property drainage is free and clear of debris.
