Eastern Newfoundland has been paralyzed by a blizzard which meteorologists are calling a weather bomb with historic snow and howling winds.
A state of emergency continued Saturday in St. John’s where a new all-time daily snowfall record was set on Friday.
The provincial capital received an astonishing 76.2 cm on 17 January which buried vehicles and left huge snowdrifts making even walking difficult.
The previous daily record was 68.4 cm from 05 April 1999 with records dating to 1942.
Other communities in the Avalon Peninsula recorded more than 90 cm of snow.
Wind gusts exceeded hurricane-force in many areas with a peak of 171 km/h at Fortune Bay.
The Newfoundland premier has asked the federal government to bring in the army for help in the cleanup effort.

Snow settles in Moncton, 05 Dec 2019 (Dearing)
The latest low pressure to invade the Maritimes is bringing heavy rain and strong winds to Southern New Brunswick and Northern Nova Scotia.
Environment Canada has issued a rainfall warning with up to 70 mm possible especially along the Fundy coast and strong winds gusting up to 90 km/h.
Meteorologists say that much rain is a lot for frozen ground to absorb and along with an existing snowpack could create localized flooding.
After a few days with below freezing temperatures, the small amount of snow in Greater Moncton has been taken away by the rain and a mild high of 12°C.
The forecast is calling for much colder air behind this system with some snow likely on Wednesday.

A Colorado Low tracked through the Maritimes today bringing mixed precipitation and strong winds.
The system brought the first major snowfall to Nova Scotia with 23 cm at Halifax Stanfield Airport and lesser amounts in the city but it caught drivers and plow operators off guard creating gridlock.
About 10 to 20 cm of snow also fell in central and southwestern New Brunswick where some schools closed with slippery road conditions.
Greater Moncton had a rain/snow mix this morning with 2 cm before it changed to rain.

Tree leaning on power lines, 01 Nov 2019 (NB Power)
Blustery but mild weather on Halloween continued throughout the first day of November in Southeast New Brunswick.
A cold front created strong winds with a sustained high of 64 km/h and a peak gust of 94 km/h at the Greater Moncton Airport.
Many trees and branches – already weakened by Dorian earlier this fall – came down onto power lines with NB Power dealing with almost 60,000 customers without electricity by late Friday.
Environment Canada warned of gusts up to 110 km/h in the Tantramar Marsh which forced the shutdown of the Trans Canada Highway between Amherst and Sackville until winds subsided.
The daytime high on 01 November was 19.4°C which was slightly warmer than the October maximum of 19.3°C.
The same storm system also hit Quebec where more than one million customers lost power, one man was killed by a falling tree and a canopy collapsed at a service station.
Fallen leaves, Centennial Park, Moncton, 14 Oct 2019 (Dearing)
Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.

Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.
Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.
Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.
