Back-to-back low pressure systems brought a messy mix of precipitation to much of the Maritimes over the weekend.

Rain began falling Saturday with a near record warm high of 11 C in Greater Moncton which melted any snow on the ground.

However, the next system brought colder temperatures and more than ten hours of ice pellets (sleet) in Southeast New Brunswick sometimes mixed with snow and freezing rain.

About 15 cm of ice pellets and snow accumulated Sunday which forecasters say is quite rare and it was certainly heavy to move.

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.

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.

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.

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.

Messy mix falls over Maritimes

After exiting Ontario, a Colorado Low moved into the Maritimes bringing freezing rain and rain to Nova Scotia along with mixed precipitation to Southeast New Brunswick.

The system shut down schools in many parts of the region on Tuesday with icy roads being a major factor.

Greater Moncton had several hours of freezing rain and ice pellets mixing with snow (3 cm) and later rain (15 mm) as the temperature climbed slightly above freezing.

Northern and western New Brunswick received mostly snow with 10 cm in Fredericton, 18 cm in Miramichi and 27 cm in Woodstock.

A low pressure system delivered an icy mix of precipitation to Southern Ontario on Sunday with freezing rain and ice pellets turning highways and walkways into ice rinks.

Ontario Provincial Police say heavy snow shut down a section of Highway 401 near Kingston after a 30 to 40 vehicle pileup with more than a dozen injured and one fatality.

At least 500 road crashes were reported in the Greater Toronto Area and numerous flights were either cancelled or delayed at Pearson Airport.

Tens of thousands lost electricity after ice-laden tree branches fell onto power lines,

Several towns and cities were forced to cancel their Santa Claus Parades due to the extreme weather.
