Alerts in Effect
Tropical Cyclone Information StatementIssued at 20:48 Sunday 20 September 2020
For Hurricane Teddy.
The next information statement will be issued by 3:00 a.m. ADT.
Hurricane Teddy will approach Nova Scotia early on Tuesday and is expected to transition to a large and intense Post-Tropical Storm as it draws nearer to the province Tuesday night. Teddy will bring heavy rain, strong winds and heavy pounding surf to much of the Maritimes and Newfoundland on Tuesday and Wednesday.
1. Summary of basic information at 9:00 p.m. ADT.
Location: near 29.4 North 63.4 West.
About 353 kilometres south-southeast of Bermuda.
Maximum sustained winds: 165 kilometres per hour.
Present movement: North-northwest at 15 kilometres per hour.
Minimum central pressure: 964 millibars.
Teddy is currently a category two hurricane over the Tropical Atlantic southeast of Bermuda. It will move generally northward tonight and Monday, passing east of Bermuda. Teddy is expected to transition Monday night and Tuesday into a large and intense post-tropical storm. The storm will move into the Maritimes marine areas south of Nova Scotia on Tuesday then turn northeastward towards Cape Breton Tuesday night and Wednesday morning. Post-Tropical Storm Teddy is then expected to move across Newfoundland on Wednesday.
2. Public impacts and warnings summary:
A Tropical Storm Watch is now in effect for the Atlantic coast of Mainland Nova Scotia. These watches will likely be extended to parts of Cape Breton later tonight and may be upgraded to Tropical Storm Warnings as the storm draws closer.
Too early to give specific wind forecasts, but most parts of the Maritimes and southern Newfoundland will see tropical storm force winds gusting in the 70 to 90 km/h range. Exposed areas along the Atlantic coasts of Nova Scotia where Teddy makes its closest approach could see higher gusts of 90 to 110 km/h or possibly slightly stronger. These winds will likely cause power outages, breaking branches and possible tree falls, especially due to trees still having their full foliage.
The highest rainfall amounts are likely to be just north and west of Teddy's eventual track through the region, which for now would encompass most of mainland Nova Scotia, Cape Breton, the eastern half of Prince Edward Island, and parts of southwestern Newfoundland. Rainfall amounts in these areas could exceed 50 mm, with isolated areas possibly exceeding 75 mm.
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, large waves will build into the coast late on Tuesday into Wednesday, with the largest 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. Rough and pounding surf, localised flooding and coastal erosion are likely in vulnerable areas.
3. Marine impacts and warning summary:
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.
