Here comes the rain (and snow) again…

Snow settles in NE Moncton before changeover to rain, 10 Nov 2018 (Dearing)

Without a doubt, it has been a soggy couple of months in Greater Moncton.

More 100 mm of rain – almost a month’s worth – has fallen during the first week of November alone and precipitation was 50 percent above normal in October.

Another low pressure system arrived in the Maritimes this weekend with a mix of rain and snow in New Brunswick.

Several centimetres of snow fell in Greater Moncton and after a changeover to rain as much as 30 mm could fall before it ends later today.

October 2018 – Cool and wet

October 2018 proved to be very different from October 2017 in Southeast New Brunswick.

While it was warm and dry last year in Greater Moncton (the second warmest October since 1881), it was the opposite this year – cool and wet.

Temperatures were below normal with only one day reaching 20°C and a hard frost arrived by mid-month.

Only seven days were dry with three major rainfall events and snow fell on three days – briefly settling on the ground twice.

Nor’easter follows record cold

Snow settles in NE Moncton before a changeover to rain, 28 Oct 2018 (Dearing)

A frosty Saturday morning proved record breaking at the Greater Moncton International Airport when the thermometer plunged to -6.6°C which breaks the previous cold low from 1998 by 0.1°C.

Frigid temperatures were also set in Edmundston at -12.2°C, Woodstock at -11.7°C and Saint John at -8.4°C with weather records going back to 1886.

The Arctic cold was soon replaced by a low pressure system with some tropical moisture from the remnants of Hurricane Willa.

The early season Nor’easter brought snow, ice pellets and eventually rain to the Maritimes along with gusty winds which uprooted trees in parts of New England.

Say it isn’t snow!

Snow settles on grass, vehicles and rooftops in NE Moncton, 25 Oct 2018 (Dearing)

Even by New Brunswick standards, snow in October is not very common.

But a low pressure system dropped more than 15 cm of heavy, wet snow over western and northern parts of the province creating commuter chaos in Fredericton yesterday.

After getting drenched with 38 mm of rain, Greater Moncton received a light coating of snow this morning which stuck to rooftops, vehicles and grassy areas but it melted by midday.

Here are some snowfall totals (in cm) from volunteer observations:

  • Charlo/Belledune area. 23 cm
  • Woodstock. 16 cm
  • Fredericton. 15 cm
  • Miramichi. 13 cm
  • Grand Falls. 10 cm
  • Moncton. 3.4 cm

Early season snow in N.B.

Snow has come early for parts of northern and western New Brunswick as a low pressure system brings heavy rain elsewhere in the province.

Fredericton recorded a few centimetres of snow today while Greater Moncton is expecting mostly rain – possibly 15 to 25 mm – starting tonight.

Environment Canada says up to 15 cm of snow could fall by Wednesday night in the north and west with greater amounts over high terrain.

First snow flurries of fall!

Low clouds and cold gusty winds across the warm Gulf of St. Lawrence and Bay of Fundy produced the first snow flurries of the season throughout the Maritimes today.

Greater Moncton actually had occasional snow squalls throughout the afternoon but there was no accumulation.

Some areas of New Brunswick and Nova Scotia did record slight amounts on the ground.

Environment Canada issued a special weather statement with up to 10 cm of snow possible for the Cape Breton Highlands.

Strong winds across Atlantic Canada

A fast-moving cold front passed through the Maritimes today on its way to Newfoundland.

Powerful winds developed as a result which knocked out electricity to tens of thousands of customers across New Brunswick, Prince Edward Island and Nova Scotia.

The Greater Moncton International Airport recorded a gust of almost 90 km/h late this morning with Cape Breton Island reporting winds of more than 100 km/h.

Many locations across Newfoundland had hurricane-force gusts including Bonavista at 126 km/h, Wreckhouse at 107 km/h and St. John’s at 104 km/h.

The cold front also affected Southern Quebec yesterday with gusts of more than 80 km/h in Montreal and Quebec City.

Fall colours reach peak

The brilliant fall foliage hues of red, orange and gold have reached their peak in Southeast New Brunswick.

Leaves have already begun falling to the ground and the season is already past peak across the northern part of the province.

Experts say the colours have peaked about a week later than usual thanks to a hot, dry summer which caused stress for leaves.

The drought was relatively short-lived with a plentiful amount of rain recorded so far this autumn.

Michael strikes Florida panhandle

Hurricane Michael slammed the coastline of the Florida panhandle making landfall mid-afternoon as a Category 4 storm.

Michael is the strongest hurricane to hit the United States since Camille in 1969 with winds up to 250 km/h and as much as 300 mm of rain.

Warmer than normal water temperatures in the Gulf of Mexico helped fuel Michael and the accompanying storm surge which submerged communities near Panama City.

Forecasters say the storm was downgraded to a Category 1 as it crossed Georgia.

Michael is expected to weaken to a post-tropical depression by the time it passes south of Nova Scotia on Saturday.

Leslie responsible for rain

Hurricane Leslie is churning well south of the Maritimes and is not forecast to impact the region directly but the storm is indirectly responsible for heavy rain.

The sheer size of the storm – Leslie is more than 1,000 km wide – caused a low pressure system to stall bringing lots of rain to Nova Scotia, New Brunswick and Prince Edward Island.

Here are some totals from the rain event:

  • Greater Moncton. 32.6 mm
  • Saint John. 46.7 mm
  • Charlottetown. 47.2 mm
  • Halifax Stanfield Airport. 24.7 mm
  • Yarmouth. 43.2 mm
