Update: Environment Canada has lifted all warnings for HRM in regards to Hurricane Teddy

Tropical storm warning in effect

Tropical storm force winds of 60 gusting to 90 km/h over exposed areas from Tropical Storm Teddy can be expected over the above regions.

Tropical storm force winds ahead of Hurricane Teddy expected to begin affecting parts of Nova Scotia late on Tuesday, accompanied by rain at times heavy in the afternoon and evening.

Potential wind gusts: 65 to 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 Tuesday into Late Wednesday.

Remarks: Tropical storm force northeasterly winds will develop across much of Nova Scotia ahead of Hurricane Teddy on Tuesday. Winds are expected to gust to 80 to 100 km/h over exposed areas and along parts of the coast Tuesday afternoon and evening. Another period of strong winds is possible Wednesday morning over easternmost sections of Nova Scotia as Teddy makes its closest approach to the
province.

These winds could break tree branches potentially resulting in downed utility lines. Stay away from the shore – the combination of surge and large waves could result in dangerous rip currents and the risk of being pulled out to sea.

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

.

Storm surge warning in effect

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

Maximum water levels: storm surge up to 50 cm

Maximum wave heights:7 to 9 metres, breaking higher along parts of the coast.

Locations: From Yarmouth County east to Guysborough.

Time span: For the Eastern Shore, near the high tides Tuesday evening and wednesday morning. For the Southwest Shore near high tides on tuesday morning and Tuesday evening.

Remarks: The main risk is for very large waves, rough and pounding surf and a threat for rip currents. On Tuesday 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. 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.

High waves combined with the surge may cause damage along the coast. Coastal erosion is likely in vulnerable areas. Coastal flooding is possible along the shoreline.

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

.

Rainfall warning in effect

Rain, at times heavy, is expected.

Total rainfall amount: 50 to 75 mm, possibly reaching 100 mm in areas of heaviest rain.

Locations: Lunenburg, Halifax, and Guysborough Counties

Time span: beginning late Tuesday morning and continuing into Wednesday.

Remarks: The initial rain bands ahead of Hurricane Teddy will reach the Atlantic coast of Nova Scotia late Tuesday morning. Rain will be heavy at times through the afternoon and then diminish somewhat in the evening. A second burst of heavier rain is expected just ahead of Teddy as it approaches the coast overnight on Tuesday and into Wednesday morning. Total amounts may exceed 50 mm by 6 a.m. Wednesday, with total rainfall possibly reaching 100 mm in areas of heaviest rain by Wednesday night. This warning is likely to be expanded with future updates.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Rainfall warnings are issued when significant rainfall is expected.

.

Wind warning in effect

Strong winds that may cause damage are expected or occurring.

Maximum gusts: northeasterly 90 to 100 km/h along parts of the coast.

Locations: Along the Atlantic coast of Nova Scotia from Digby County to Victoria County

Time span: Tuesday afternoon until late Tuesday evening.

Remarks: Winds will strengthen over the coast of Nova Scotia on Tuesday as Teddy approaches from the south. Winds will reach warning criteria over the Atlantic and lower Fundy coasts of mainland Nova Scotia on Tuesday afternoon, and over eastern Cape Breton on Tuesday evening.

Late Tuesday evening and into the overnight hours, winds will shift to southeasterly and diminish somewhat over eastern Nova Scotia before strengthening again overnight and Wednesday morning as Teddy crosses the province. Winds will remain near warning criteria over western mainland Nova Scotia through the night as they shift to northwesterly.

Damage to buildings, such as to roof shingles and windows, may occur. High winds may toss loose objects or cause tree branches to break.

Wind warnings are issued when there is a significant risk of damaging winds.

For Hurricane Teddy.

A Tropical Storm Warning is in effect for the Atlantic coastline of mainland Nova Scotia and Cape Breton.
Tropical Storm Watches are in effect for or the rest of Nova Scotia, Prince Edward Island, Iles de la Madeleine, and southwestern Newfoundland.

Hurricane Teddy will spread tropical storm force winds to parts of Nova Scotia on Tuesday. Thereafter it 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.

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

Location: near 32.9 North 62.8 West.

About 185 kilometres east-northeast of Bermuda.

Maximum sustained winds: 150 kilometres per hour.

Present movement: North at 30 kilometres per hour.

Minimum central pressure: 960 millibars.

Teddy is currently a category one hurricane over the tropical Atlantic northeast of Bermuda. It will move generally northward tonight and enter the Canadian response zone on Tuesday. Thereafter Teddy is expected to transition into a powerful post-tropical storm. On Wednesday post-tropical Teddy will turn northeastward and head toward eastern Nova Scotia and then southwestern Newfoundland.

2. Public impacts and warnings summary:

a. Wind.
Tropical storm warnings are in effect for the Atlantic coast of mainland Nova Scotia for Tuesday. Tropical storm watches are in effect for the rest of Nova Scotia, Prince Edward Island, Iles de la Madeleine, and southwestern Newfoundland. These areas will likely see winds gusting up to 90 km/h during the day. Given trees are still in full leaf, these winds could cause limbs to break with isolated tree falls, likely leading to many power outages.

b. Rainfall.
Rainfall warnings are in effect from Lunenburg to Guysborough county.
Rain ahead of Teddy will likely reach Nova Scotia by Tuesday afternoon and will continue in many areas into Wednesday. 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 reaching 75 to 100 mm.

c. Surge/Waves.
Storm surge warnings are in effect along the Atlantic coast of Nova Scotia from Shelburne County to Halifax to Guysborough.
Large swells will gradually build south of the region tonight and Tuesday, with the highest waves expected to reach the Atlantic coast late Tuesday into Wednesday morning. Wave of up to 9 metres are expected, and will break higher along parts of the coast. For southern Newfoundland, the largest waves are expected to reach southern coastlines on Wednesday and will reach 7 metres near the coast. Elevated water levels will accompany the storm, 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 later Tuesday night 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 erosion are likely in vulnerable areas, even outside of the times of high tide.

3. Marine impacts and warning summary:

High water level warnings are in effect from Shelburne county to Guysborough county. Hurricane force wind warnings are now in effect for offshore Maritime waters, with storm warnings for most remaining waters south of Nova Scotia. Gale warnings are in effect for southern Gulf of St. Lawrence waters as well as the southwestern Grand Banks. Teddy will also bring extremely high significant wave heights of 10 to 15 metres to extreme offshore Maritimes waters by late Tuesday. High water level warnings are in effect from Shelburne county to Guysborough county.
