Dorian damage in Halifax’s West End, 08 Sept 2019 (NS Power)
Hurricane Dorian has left a path of destruction across the Maritime Provinces despite being downgraded as it crossed the region.
The Canadian Hurricane Centre says Dorian was an intense post-tropical storm as it made landfall at 7:15pm ADT Saturday in Sambro, 25 km southwest of Halifax.
Dorian brought destructive winds, flooding rains and powerful storm surges to much of Nova Scotia, southern New Brunswick and Prince Edward Island.
A construction crane collapsed and century old trees toppled onto homes, businesses, vehicles and streets in Halifax.
Public works staff are scrambling to clean up the mess and power crews are trying to restore electricity to the tens of thousands without it.

If it wasn’t for the remnants of Tropical Storm Erin, August would have been another dry month in Greater Moncton.
Almost 50 mm of rain fell on 29 August which is more than all of July and pushed the monthly total above normal.
Daytime highs weren’t hot but were consistently warm until a decidedly fall-like four days near the end of the month.

Post-tropical depression Erin interacted with an incoming low pressure system to produce lots of rain in the Maritimes.
Environment Canada says the heaviest amounts were recorded in northern Nova Scotia and the Annapolis Valley – Parrsboro and Greenwood each had more rain from this storm than all of July and August combined.
Some roads were damaged and even washed out by surface runoff or flooding.
Erin’s direct path along Nova Scotia’s south shore produced wind gusts up to 80 km/h.
The storm brought tropical air with a high of 23°C in Greater Moncton on Friday but a humidex of 32.

- Parrsboro 162

Post-tropical storm Chris quickly moved across eastern Newfoundland late Thursday and early Friday with powerful winds, heavy rainfall and rough surf along the coast.
Gander recorded almost 80 mm of rain (almost a month’s worth), the southern Avalon Peninsula had high water swells of 6 to 8 metres above normal while Bonavista and Cape Pine recorded wind gusts above 100 km/h.
The Canadian Hurricane Centre issued its final bulletin for Chris early Friday as the storm sped off into the North Atlantic.

Chris is now a post-tropical storm with sustained winds of 110 km/h and is expected to make landfall in eastern Newfoundland near Cape St. Mary’s tonight.
The Canadian Hurricane Centre says strong winds combined with low pressure will create large waves and pounding surf giving the risk of coastal flooding along the southern Burin and Avalon Peninsulas.
Besides a wind warning, a rainfall warning has been issued with possible amounts of 50 mm or more and 20 mm an hour in the heaviest showers.
The remnants of Chris will drift away into the North Atlantic by early Friday morning.

The U.S. National Hurricane Center finally downgraded Matthew to a post-tropical cyclone today after pounding North and South Carolina with strong winds, heavy rain and record flooding before moving east out to sea.
Matthew made landfall near Charleston, South Carolina yesterday as a category 1 hurricane after hugging Florida’s Atlantic coast.
Hundreds had to be rescued from floodwaters in the Carolinas including one woman who was forced to cling to a tree overnight before emergency workers arrived.
The most powerful Atlantic storm in a decade has claimed at least 20 deaths in the Southeastern United States and more than 900 in the Caribbean, mostly in Haiti.

The warmth of summer is expected to continue well into September in Southeast New Brunswick according to Environment Canada.
Meteorologists say the waters surrounding the Maritimes (Bay of Fundy, Atlantic Ocean, Northumberland Strait and Gulf of St.Lawrence) are about 2-3 Celsius above normal for this time of year.
Warm water generates energy which will help elevate temperatures throughout the region.
Precipitation is difficult to predict at this time of year since remnants of a post-tropical storm could easily deliver a hefty rainfall in just a few hours.

By the time Colin had arrived in Canadian waters earlier today, it had become a post-tropical storm – essentially a strong low pressure system.
Much of Florida had received heavy rain from Colin before the storm moved into the Atlantic Ocean and tracked northeastward.
Wind was not a factor for the Maritimes but heavy rain fell in eastern Nova Scotia, Cape Breton Island and Newfoundland.
Greater Moncton received less than 20 mm of rain between remnants of Colin and another low pressure system which was crossing New Brunswick.
Colin was the third named storm of the 2016 Atlantic Hurricane Season – after Bonnie in late May and Alex in mid-January.

After a warmer than average May in Southeast New Brunswick, hopes were high that June would follow suit but that was not the case.
Environment Canada reports the average monthly temperature was 1.5 C below normal in Greater Moncton with precipitation about 50 percent higher than usual.
Overnight lows were generally cool throughout the month and the maximum temperature barely climbed to 27 C.
Heavy rainfall from post-tropical storm Bill in the last third of the month caused flooding in the low lying areas of Sackville and Amherst.

What was left of post-Tropical Storm Bill drenched much of the Maritimes especially near the New Brunswick-Nova Scotia border.
More than 130 mm of rain has fallen in that area since yesterday with flooding in the Sackville area and also in Amherst where a nursing home had to be evacuated.
Environment Canada reports about 65 mm of rain in Greater Moncton by late this afternoon with more than 80 mm on Grand Mahan Island.
Halifax and Charlottetown have each received almost 60 mm of rain.
