Freshly fallen snow in west end Moncton, 29 Nov 2018 (Dearing)
Southeast New Brunswick has been under a gloomy, grey sky all week thanks to a couple of low pressure systems.
The first one brought rain, drizzle and fog while the second brought heavy, wet snow to make this November one of the snowiest in recent memory.
Eastern New Brunswick got the brunt of the snow with Miramichi picking up a whopping 43 cm of snow while Greater Moncton had a hefty 28 cm.
Most of the snow in Nova Scotia fell over northern and eastern areas with heavy rain falling elsewhere.
Strong winds up to 89 km/h caused a storm surge along the Gulf of St. Lawrence coast.
Gusts of more than 100 km/h were reported on Prince Edward Island and Cape Breton Island.
Temperatures sunk early Monday across the Maritimes with some New Brunswick locations shattering records by almost five degrees dating back to the 1880’s.
The bitter cold precedes another storm system which could bring up to 25 cm of snow to southern New Brunswick, most of Prince Edward Island and northern Nova Scotia.
While it plunged to -14.7°C in Greater Moncton, the 1936 record still stands at -16.7°C.
Here are some of the new record lows set in the region on 19 November:
- Bathurst, NB -22.5°C
- Woodstock, NB -21.4°C
- Miramichi, NB -20.2°C
- Kouchibouguac, NB -20.0°C
- Summerside, PE -15.7°C

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.
