Just days into the new year, a low pressure system has brought mostly snow to Atlantic Canada especially near the ocean.

For most of Nova Scotia, it was winter’s first major snowfall with up to 15 cm at Halifax Stanfield Airport and nearly 40 cm in Sydney.

The storm grazed Greater Moncton with only 3 cm of snow.

After leaving the Maritimes, the system brought 42 cm snow to St. John’s, Newfoundland and 30 cm to the Burin Peninsula with a peak wind gust of 106 km/h in Bonavista.

Meantime, forecasters say another low pressure system is coming midweek.

Wintry mix for New Year’s Eve

The same storm system which impacted Ontario and Quebec is now creating travel havoc in the Maritimes with a mixed bag of precipitation.

Snow along with ice pellets began in Southwest New Brunswick on New Year’s Eve morning and gradually spread to Greater Moncton by early afternoon.

About 14 cm of snow and ice pellets could accumulate in the Southeast before a changeover to rain around midnight as temperatures rise above freezing.

Snowfall warnings have been posted in western and northern New Brunswick with 15 to 30 cm likely with lesser amounts for Prince Edward Island and mostly rain is forecast for mainland Nova Scotia.

UPDATE

Moncton received 5.4 cm of snow, Saint John had 3.4 cm while about 10 cm fell in Fredericton but near 30 cm in Woodstock.

Storm sweeps Ontario

Mild but stormy conditions

Another intense low pressure system moved through the Maritimes on the weekend bringing a new round of heavy rain and strong winds.

After a bone-chilling start, winds changed direction and a southerly flow pushed the high in Greater Moncton to 13.8°C – close to the record of 13.9°C from 2008.

Winds were strong with gusts up to 87 km/h in Southeast New Brunswick and a peak of 91 km/h reported in Bathurst.

As the storm headed to Newfoundland, cold air plunged into the region and temperatures fell below freezing and may stay that way for several days.

Wind & rain cause damage

Strong winds and heavy rain from a strong low pressure system caused damage to properties and localized flooding in New Brunswick and Nova Scotia.

The Saint John area was hard hit with wind gusts up to 95 km/h which led to power outages and roof damage to at least two apartment buildings.

No one was hurt but all tenants were evacuated and assisted by the Red Cross.

Many roads were closed due to flooding or fallen trees and there were voluntary evacuations in Sussex in low lying areas.

The storm also brought mild, record-breaking temperatures with highs of 11°C in Edmundston and 12°C in Bathurst and Woodstock.

Greater Moncton hit 13.7°C but the record for 10 December was 15°C from 1957.

Rainfall totals (in mm) as of 8am on 10 December 2019:

  • Mechanic Settlement, NB  94 mm
  • Saint John Airport  63 mm
  • Kejimkujik NP, NS  53 mm
  • Dorchester, NB  50 mm

Heavy rain may cause flooding

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.

Early snow for southern Ontario & Quebec

An early winter storm tracked south of the Great Lakes on Monday and brought snow to Southern Ontario and Southern Quebec.

Snowfall amounts generally ranged between 10 and 30 cm.

Environment Canada says Toronto marked its earliest major snowfall on record with about 15 cm.

Arctic air has filtered in behind the storm prompting the city to issue an extreme cold weather alert with a possible overnight low of -15°C.

Snowfall amounts (cm), Tuesday 5pm EST:

  • Montreal 20
  • Quebec City 20
  • Windsor 19
  • Hamilton 17
  • Toronto (downtown) 15
  • Ottawa 13

Fast and furious storm

A so-called bomb cyclone with wind and rain moved through the Maritimes in just a few hours today.

The intense low pressure system brought winds gusting up to 89 km/h in Saint John which uprooted some trees already weakened by Hurricane Dorian last month.

Greater Moncton recorded a peak gust of 78 km/h along with 20 mm of rain which caused some localized flooding as leaves clogged storm drains.

The winds were even stronger in Nova Scotia with a gust of 101 km/h at Halifax harbour and 106 km/h in Lunenburg which brought trees down knocking out power.

The highest gust was near Cheticamp on Cape Breton Island at 148 km/h.

Rainfall amounts across New Brunswick and Prince Edward Island ranged from 15 to 30 mm with more than double those amounts in Nova Scotia.

Strong fall storm coming

An intense low pressure system is heading to the Maritimes.

Heavy rain will start during the morning hours in Greater Moncton and strong winds will develop by midday.

Environment Canada says rainfall amounts could reach 50 mm while easterly wind gusts of 70 km/h or higher are likely.

Some trees may be at risk of falling after being weakened by Hurricane Dorian last month.

Many leaves will undoubtedly drop which could plug storm drains causing localized flooding.

Manitoba declares state of emergency

The Manitoba government declared a state of emergency on Saturday after a powerful storm dumped heavy rain, freezing rain, snow and wind to southern portions of the province this week.

Amid the early winter blast, Manitoba Hydro is trying to restore electricity to thousands of residents after numerous trees and branches – many still covered in leaves – fell onto power lines with winds gusting up to 100 km/h.

The storm was so bad it forced the temporary closure of the Trans Canada Highway from Winnipeg to the Saskatchewan border.

Southern Manitoba got blasted after a Colorado Low moved in from the United States where it brought dramatic temperature drops and heavy snow to the Great Plains states.

The next concern for local emergency measures officials will be flooding as the snow melts given the rising temperatures forecasted over the next few days.

Snowfall totals as of 1pm CDT on Saturday, October 12th:

  • Carberry  74 cm
  • Morden  64 cm
  • Winnipeg  34 cm
  • Dauphin  30 cm
  • Brandon  29 cm
