Storm Surge Warning

Issued at 04:50 Tuesday 22 September 2020
Summary

High Storm Surge levels and very large waves are expected to impact the coast.

Maximum water levels: storm surge of up to 50 cm except higher in areas where large waves break on shore

Maximum wave heights: 7 to 9 metres, possibly exceeding 10 metres over eastern areas.

Locations: From Yarmouth County east to Cape Breton.

Time span: For the Southwest Shore near high tides on this morning and this evening. For the Eastern Shore, near the high tides this evening and wednesday morning. For Cape Breton near high tide early Wednesday.

Remarks: Storm surge and very large breaking waves are the main concern and could pose a significant threat. This morning 3-4 metre waves at the coast will build to 7-9 metres late in the day, with waves breaking higher along parts of the coast. The high waves will persist into the overnight period. Early Wednesday as Teddy approaches, eastern Nova Scotia will see very large wave and significant storm surge. Outside of the times for high tide there is still a threat for very large waves, rough and pounding surf, and local overwash. The public should observe extreme caution.

###

This is a potentially dangerous situation. High waves combined with the surge may cause damage along the coast. Coastal flooding is possible along the shoreline.

Storm surge warnings are issued when water levels pose a threat to coastal regions.

Tropical Storm Warning

Issued at 02:56 Tuesday 22 September 2020
Summary

Tropical storm force winds of 70 gusting to 100 km/h over exposed areas from Hurricane Teddy can be expected over the above regions.

Tropical storm force winds ahead of Hurricane Teddy are expected to begin affecting parts of Nova Scotia today, accompanied by rain at times heavy in the afternoon and evening. A second swath of strong southerly winds will briefly affect eastern mainland Nova Scotia and Cape Breton early Wednesday morning.

Potential wind gusts: 80 to 90 km/h possibly reaching 100 km/h over exposed areas and along parts of the coast.

Locations: Coastal regions of mainland Nova Scotia and Cape Breton

Time span: From noon today until later tonight. A second period of strong winds can be expected over eastern Nova Scotia Wednesday morning.

Remarks: Tropical storm force northeasterly winds will develop across much of Nova Scotia ahead of Hurricane Teddy today. Winds are expected to gust to 80 to 100 km/h over exposed areas and along parts of the coast this afternoon and evening. A period of very strong southerly winds gusting to 90 to 100 km/h will affect eastern mainland Nova Scotia and Cape Breton Wednesday morning as the center of Post-Tropical Teddy crosses eastern Nova Scotia.

###

These winds could break tree branches potentially resulting in downed utility lines.

A tropical storm warning means that tropical storm conditions (sustained winds near 65 km/h or more) are expected over parts of the region within 24 hours.

By nature, a tropical storm also implies the threat of local flooding from heavy rainfall - consult your local area forecast for possible rainfall warnings.

Tropical Cyclone Information Statement

Issued at 02:49 Tuesday 22 September 2020
Summary

For Hurricane Teddy.

The next information statement will be issued by 9:00 a.m. ADT.

Hurricane Teddy will spread tropical storm force winds to parts of Nova Scotia today. Thereafter Teddy is expected to transition to a powerful Post-Tropical Storm as it brings heavy rain, strong winds and heavy pounding surf to much of the Maritimes and southern Newfoundland. The center of Post-Tropical Storm Teddy is expected to make landfall along the eastern shore of Nova Scotia Wednesday morning.


1. Summary of basic information at 3:00 a.m. ADT.

Location: near 37.4 North 61.8 West.

About 815 kilometres south of Halifax.

Maximum sustained winds: 155 kilometres per hour.

Present movement: North at 41 kilometres per hour.

Minimum central pressure: 956 millibars.

Teddy is currently a category two hurricane over the Atlantic Ocean well south of Halifax. It will move north-northwestward for a time today as it enters the Canadian response zone and then gradually transition into a powerful post-tropical storm. On Wednesday post-tropical Teddy will turn northeastward and travel across eastern Nova Scotia in the morning then weaken as it moves into the Gulf of St. Lawrence.

2. Public impacts and warnings summary:

a. Wind.
Wind and Tropical Storm warnings are in effect for the Atlantic coastline of Nova Scotia from Digby to Cape Breton, where wind gusts of 80 to 100 km/h are expected today. Tropical storm watches are in effect for the remainder of Nova Scotia, as well as Prince Edward Island, Iles de la Madeleine, and southwestern Newfoundland where winds gusting 70 to 80 possibly reaching 90 km/h are possible later today and tonight. Given trees are still in full leaf, these winds could cause limbs to break with some tree falls, likely leading to many power outages. In addition a Les Suetes wind warning is in effect for western Cape Breton and a Wreckhouse wind warning for southwestern Newfoundland.

b. Rainfall.
Rainfall warnings are in effect for all of Nova Scotia except western most regions, and for Prince Edward Island. Rain ahead of Teddy will likely reach the region by this afternoon and will continue in many areas into Wednesday. Rainfall amounts in these areas could exceed 50 mm, with isolated areas possibly reaching 75 to 100 mm.

c. Surge/Waves.
Storm surge warnings are in effect along the Atlantic coast of Nova Scotia from Yarmouth County through to eastern Cape Breton County. Large swells will continue to build toward the Atlantic coast today, with the highest waves expected to reach the Atlantic coast later today into Wednesday morning. Waves of up to 8 to 10 metres are expected, and will break higher along parts of the coast. For southern Newfoundland, the largest waves, in the 6 to 8 metres range, are expected to reach southern coastlines on Wednesday. Note that the waves will break higher along parts of the coast.

Elevated water levels will develop in conjunction with these waves, mainly for parts of the Atlantic coast of Nova Scotia today and for southwestern Newfoundland on Wednesday. There is also a chance for Prince Edward Island and Iles de la Madeleine later tonight or Wednesday.

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 infrastructure damage and erosion are likely in vulnerable areas, even outside of the times of high tide.

3. Marine impacts and warning summary:

Hurricane force wind warnings are in effect for most offshore Maritime marine waters, with storm and gale warnings for remaining waters south of Nova Scotia. Gale warnings are in effect for most Gulf of St. Lawrence waters as well as the southwestern Grand Banks. Teddy will also bring extremely high significant wave heights as high as 15 metres to extreme offshore Maritimes waters by late today. In addition High Water Level warnings are in effect for Lurcher, Southwestern Shore, Eastern Shore and Fourchu.
