Hurricane Teddy Update For Nova Scotia – Sunday 9:00am


From Environment Canada – – 8:46AM 2020-09-20

Hurricane Teddy poised to impact Atlantic Canada Tuesday and Wednesday.

Hurricane Teddy will likely reach offshore waters south of Nova Scotia on Tuesday as a hurricane, and will then impact Atlantic Canada and the Gulf of St. Lawrence region as a strong post-tropical storm on Tuesday into Wednesday.

Teddy is currently a category three hurricane over the Tropical Atlantic well southeast of Bermuda. It will slowly move up during the next two days, passing east of Bermuda on Monday. This is when it will begin to accelerate towards Nova Scotia. When it reaches Canadian waters south of the Maritimes it will be a category two hurricane, but is expected to be a very dangerous post-tropical storm as it moves through eastern Nova Scotia and southwestern Newfoundland.

Possible impacts:

A. Public

Rainfall could be significant, especially north and west of Teddy’s track. At this point, the highest rainfall amounts are likely for eastern Nova Scotia and the south coast of Newfoundland. Most regions will see some tropical storm force winds, and south of the forecast track winds may reach hurricane force. Power outages are likely due to breaking branches and possible tree falls, especially due to trees still having their full foliage. Every effort should be made to secure temporary structures.

B. Marine

As Hurricane Teddy moves into our waters, there is a reasonable chance of hurricane force winds near and south of the track, mainly over southern Atlantic Canada forecast waters. Tropical storm force winds are likely farther north into the Gulf of St, Lawrence and southern coastal Newfoundland. There will also be large waves, again mainly over southern waters.

C. Surge/Waves

Very large waves will move into southern forecast waters overnight into Monday and will build along the Atlantic coast of Nova Scotia on Tuesday, with the highest waves expected late in the day. For southern Newfoundland, fairly large waves will build into the coast late on Tuesday into Wednesday, with the worst waves expected on Wednesday. Storm surge is likely, mainly for parts of the Atlantic coast of Nova Scotia on Tuesday and for southwestern Newfoundland on Wednesday. There is also a chance for Prince Edward Island and the Magdalen Islands late on Tuesday.

The highest risk is the combination of the very large waves combining with the storm surge to cause dangerous conditions along the Atlantic coasts of Nova Scotia and Newfoundland, with rough and pounding surf, localised flooding and coastal erosion.
