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.
Roof damage at apartment building, Heather Way, 10 Dec 2019 (City of Saint John)
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.

Temperature contrast 8pm, 12 Nov 2019 (earth nullschool.net)
Snow began falling in Southeast New Brunswick Monday night and later changed to freezing rain and then rain by Tuesday afternoon.
The temperature climbed to a balmy 14°C in Greater Moncton and 18°C in Greenwood, Nova Scotia.
But as the low pressure system moved out of the Maritimes toward Newfoundland, winds shifted to the northwest causing the thermometer to drop rapidly Tuesday night with a return to snow when it fell to freezing again.
Overnight low records could be challenged in the region by early Thursday as cold Arctic air takes hold.

Blustery but mild weather on Halloween continued throughout the first day of November in Southeast New Brunswick.
A cold front created strong winds with a sustained high of 64 km/h and a peak gust of 94 km/h at the Greater Moncton Airport.
Many trees and branches – already weakened by Dorian earlier this fall – came down onto power lines with NB Power dealing with almost 60,000 customers without electricity by late Friday.
Environment Canada warned of gusts up to 110 km/h in the Tantramar Marsh which forced the shutdown of the Trans Canada Highway between Amherst and Sackville until winds subsided.
The daytime high on 01 November was 19.4°C which was slightly warmer than the October maximum of 19.3°C.
The same storm system also hit Quebec where more than one million customers lost power, one man was killed by a falling tree and a canopy collapsed at a service station.

Fewer trick or treaters are expected to be spooking neighbourhoods in Greater Moncton thanks to heavy rain and strong winds.
A low pressure system could bring at least 30 mm of rain to Southeast New Brunswick over the next 24 hours.
Potentially hurricane-strength winds are expected tomorrow ahead of a cold front but temperatures will be warm reaching the high teens.
Environment Canada has issued wind warnings with gusts from 60-90 km/h and possibly up to 110 km/h in the Tantramar Marsh.
Forecasters say the wind may cause damage to buildings such as to roof shingles and windows.
The wind may not die down until early Saturday.
Irishtown Nature Park, 05 October 2019 (Dearing)
Barely a day after the coolest daytime high in five months, temperatures climbed into the high teens in New Brunswick and low 20’s in Nova Scotia.
This proves just how changeable October can be.
Greater Moncton has wrapped a third day at around 17°C.
The maximum October temperature is typically at least 20°C and it is still possible to reach it before the end of the month.

Almost 50 mm of rain fell on 29 August which is more than all of July and pushed the monthly total above normal.
Daytime highs weren’t hot but were consistently warm until a decidedly fall-like four days near the end of the month.

Post-tropical depression Erin interacted with an incoming low pressure system to produce lots of rain in the Maritimes.
Environment Canada says the heaviest amounts were recorded in northern Nova Scotia and the Annapolis Valley – Parrsboro and Greenwood each had more rain from this storm than all of July and August combined.
Some roads were damaged and even washed out by surface runoff or flooding.
Erin’s direct path along Nova Scotia’s south shore produced wind gusts up to 80 km/h.
The storm brought tropical air with a high of 23°C in Greater Moncton on Friday but a humidex of 32.
Rainfall totals (mm):
- Parrsboro 162
- Greenwood 127
- Kentville 115

Forest fire near River Glade, NB, 07 May 2013 (Dearing)
A wet, cold spring and a dry, humid July have led to one of the quietest forest fire seasons in recent memory in New Brunswick.
Statistics show 152 fires for the season to date which compares to 206 fires over the past ten years.
Last year was also much busier with 242 fires recorded by the middle of August.
Provincial wildfire officials say although July was warmer than normal, high humidity levels helped prevent fires from starting and from spreading.
