Dorian packs powerful punch

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.

Heaviest snowfall of 2019

Lots of rain, freezing rain and ice pellets have been recorded so far this year in Southeast New Brunswick but snow has been somewhat scarce – until today.

A Colorado Low made its way across the continent this week bringing lots of snow to the American Midwest, Southern Ontario and Southern Quebec before arriving in the Maritimes.

Greater Moncton received 26 cm of snow followed by ice pellets and some freezing rain/drizzle along with strong winds which created poor visibility.

Snowfall amounts were fairly consistent across most of Nova Scotia with 22 cm at Greenwood and Halifax Stanfield Airport, 21 cm in Sydney but only 11 cm in Yarmouth.

Environment Canada says cold weather will replace the snow for late week with a brief warmup and rain expected this weekend.

St. George Gorge, Magaguadavic River, NB, 22 Dec 2018 (Dearing)
