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.

Enough rain already!

Another low pressure system is heading to the Maritimes with two rounds of rain starting early Tuesday stretching into early Wednesday.

Environment Canada says Greater Moncton could receive up to 35 mm of rain but some parts of the region could get 50 mm or more prompting rainfall warnings.

Winds associated with this system will be much lighter compared to the destructive winds over the weekend.

Meantime, NB Power reports about 27,000 customers remain without electricity (at 11pm AST) since restoration efforts began Sunday morning after a weekend rain and wind storm.

Powerful winds pummel Maritimes

An intense low pressure system moving up from the U.S. Eastern Seaboard brought heavy rain and strong winds to the Maritimes overnight.

The powerful hurricane-force gusts knocked out electricity to more than 100,000 customers in New Brunswick during the height of the storm.

Temperatures were very mild thanks to a southerly flow with highs exceeding 20°C in some areas including a new record of 21.7°C in Cheticamp.

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.

Willa wallops Mexico’s Pacific coast

Crashing into the Pacific coast of Mexico between Mazatlan and Puerto Vallarta, Hurricane Willa was a Category 3 storm packing wind gusts up to 193 km/h.

The eye of the hurricane struck the town of Teacapan where roofs were ripped off buildings and the streets were turned into a muddy mess.

Roads leading into Teacapan were littered with dozens of fallen utility poles.

A massive evacuation effort moved thousands into temporary shelters inland and no deaths were reported.

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

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.

Michael partly to blame for rain

Starting late Wednesday and lasting into Friday, a warm front and low pressure system eventually combined with moisture streaming northward from Tropical Storm Michael.

As these two systems began to interact, a significant amount of rain fell over parts of the Maritimes.

Rainfall summary in millimetres as of Saturday 5am ADT:

  • Doaktown: 47.2
  • Greater Moncton Airport: 39.4
  • Fredericton: 36.2

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

    Warm, summer weather picked up in September where it left off in August in Southeast New Brunswick.

    But the passage of a cold front marked a drastic temperature drop on the 18th and suddenly it felt like fall in Greater Moncton.

    The thermometer continued to plunge and sank to -1.9°C on the 25th with light, scattered frost although most vegetation was spared severe damage.

    Precipitation was actually above normal although heavy amounts fell in a handful of rainfalls.
