- Minto area 31
- Greater Moncton Airport 25
- Fredericton area 16

Tree leaning on power lines, 01 Nov 2019 (NB Power)
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.

After a cool and wet start to summer, a blast of heat is heading to the Maritime Provinces over the next few days.
Environment Canada has issued heat warnings for most of New Brunswick – excluding the Fundy coast – and western Nova Scotia while other areas under a special weather statement.
A warm, humid air mass is moving into the region today raising daytime temperatures to 30°C or more.
Humidex values near 40 are expected and overnight lows may not fall below 18°C providing little relief from the heat.
Near normal values will return late Saturday as a cold front arrives.
Heat warnings are also in place for parts of Ontario and Quebec where it climbed into the low 30s yesterday.
A tornado developed about 10 kilometres southeast of Gatineau Airport, Quebec early Sunday evening.
The tornado moved east along the Ottawa River before coming ashore on the Ontario side.
In the suburban Ottawa neighbourhood of Orléans, strong winds brought down trees and removed shingles on many homes with one person reportedly injured.
A thunderstorm also produced 2 centimetre hail in the area.
Environment Canada says the tornado was a low end EF-1 suggesting peak winds of 135 km/h and had a path length of at least 25 kilometres.
Volunteers filling sandbags in Ottawa, 25 April 2019 (City of Ottawa)
New Brunswick is not the only province experiencing severe flooding this spring – so are Ontario and Quebec.
The City of Ottawa declared a state of emergency this week as water levels rose along the Ottawa River.
The military was called in to help with flood mitigation efforts including sandbagging along with thousands of community volunteers.
In the western Laurentian mountains, the Rouge River is threatening to spill over the Bell Falls Dam and at least 60 homes have been evacuated downstream.
Due to the threat of flooding in several areas of the city, Montreal has also declared a state of emergency.
Icy conditions at Cap-Pele Harbour, 29 Dec 2018 (Dearing)
A low pressure system from Quebec moved across New Brunswick Friday and into Saturday bringing a mixed bag of precipitation.
Snow began in Greater Moncton by late afternoon which later changed to ice pellets and then freezing rain followed by rain as the temperature climbed above freezing.
After 9 cm snow, 2.5 hours freezing rain and about 7 mm rain, some of the snow melted but by early evening, the thermometer dropped below freezing again which led to ice.
While this may be the last major weather event of 2018, Environment Canada is forecasting another system bringing snow or rain for New Year’s Day.
