DISCUSSION AND OUTLOOK

----------------------

At 1100 AM AST (1500 UTC), the center of Hurricane Teddy was located 

by a NOAA Hurricane Hunter aircraft near latitude 39.6 North, 

longitude 63.7 West. Teddy is moving toward the north-northwest near 

16 mph (26 km/h), and a turn toward the north-northeast is expected 

by early Wednesday.  On the forecast track, the center will move 

over eastern Nova Scotia on Wednesday, and then near or over 

Newfoundland by Wednesday night and east of Labrador on Thursday.

Maximum sustained winds are near 105 mph (165 km/h) with higher

gusts.  Although some weakening is likely later today and Wednesday,

Teddy should be a strong post-tropical cyclone when it moves near

and over Nova Scotia.

Teddy is an extremely large hurricane. Hurricane-force winds extend 

outward up to 140 miles (220 km) from the center and 

tropical-storm-force winds extend outward up to 415 miles (665 km).

The estimated minimum central pressure is 950 mb (28.06 inches)

based on NOAA Hurricane Hunter aircraft data.

HAZARDS AFFECTING LAND

----------------------

Key messages for Teddy can be found in the Tropical Cyclone

Discussion under AWIPS header MIATCDAT5 and WMO header WTNT45 KNHC

and on the web at www.hurricanes.gov/text/MIATCDAT5.shtml.

STORM SURGE:  A dangerous storm surge is expected to produce

significant coastal flooding near and to the east of where the

center makes landfall in Nova Scotia.  Near the coast, the surge

will be accompanied by very large and destructive waves.

SURF:  Large swells generated by Teddy are affecting Bermuda, the

Lesser Antilles, the Greater Antilles, the Bahamas, the east coast

of the United States, and Atlantic Canada. These swells are likely

to cause life-threatening surf and rip current conditions.  Please

consult products from your local weather office.

WIND:  Tropical storm conditions are expected to begin in

the warning area by this afternoon.  Tropical storm conditions

could begin in the watch areas late today or early Wednesday.

RAINFALL: Through Thursday, Teddy is expected to produce rainfall

accumulations of 2 to 4 inches (50 to 100 mm) with isolated totals

of 6 inches (150 mm) across sections of Atlantic Canada.

9:05 AM ADT Tuesday 22 September 2020

Tropical cyclone information statement for:

Newfoundland and Labrador:

Burgeo - Ramea

Burin Peninsula

Channel-Port aux Basques and vicinity

Connaigre

Nova Scotia

Prince Edward Island

Québec - south:

Îles-de-la-Madeleine

For Hurricane Teddy.

The next information statement will be issued by 3:00 p.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 centre 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 9:00 a.m. ADT.

Location: near 39.3 North 63.0 West.

About 590 kilometres south of Halifax.

Maximum sustained winds: 165 kilometres per hour.

Present movement: North-northwest at 44 kilometres per hour.

Minimum central pressure: 950 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 moves through the Canadian response zone as it gradually transitions 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.
