After a severe ice storm in February, the Acadian Peninsula has been hit with bad weather again and this time by possible tornadoes.

Environment Canada is investigating after social media showed downed power poles, partially collapsed roofs and overturned concrete last night.

Severe thunderstorms can cause straight line winds with gusts as high as 130 km/h which is the same strength as the lowest level of tornado.

NB Power is working to restore electricity for thousands in northeastern New Brunswick and it could be sometime tomorrow before full restoration occurs.

The same frontal trough of low pressure moved into Greater Moncton this afternoon creating a 9 degree temperature drop (23 C to 14 C) in less than an hour and a wind direction change from southwest to northeast.

Record highs in the Maritimes

Summer-like air enveloped the Maritime Provinces with new record high temperatures set in all three provinces yesterday.

Environment Canada says more than a dozen communities in New Brunswick hit new maximums for the date including St. Stephen at 34.0 C (hot spot in Canada), Fredericton at 33.0 C and both Woodstock and Edmundston at 32.0 C.

While the thermometer reached a record-breaking 30.5 C at the Greater Moncton International Airport, the overall 18 May record for Moncton is 31.7 C from 1918.

In Nova Scotia, new records were set in Greenwood and Kejimkujik Park at 32.0 C while Summerside, Prince Edward Island warmed up to 26.3 C.

A high pressure system is pushing warm, southerly air into the Maritimes with highs approaching 30 C tomorrow in New Brunswick.

Environment Canada says humidex values could climb to 39 which has led to a Level 1 Heat Alert for Fredericton and St. Stephen.

The provincial health department issues this alert when anyone vulnerable to the heat may be affected.

Greater Moncton could break a record on Thursday if the temperature reaches the forecast high of 28 C.

St. John River remains above flood stage

Much of New Brunswick was spared the worst of a low pressure system which delivered heavy rain and created flooding over the weekend especially along the St. John River.

Environment Canada says the extreme southern half of the province had the most rain with more than 100 mm in some areas and unofficially almost 180 mm (about two months worth) fell in Mechanic Settlement, near Fundy National Park.

Moncton got off relatively easy with 40 mm of rain while Saint John had 70 mm and Fredericton reported 80 mm.

The Emergency Measures Organization says water levels should remain high but steady for the rest of this week with more rain on the way.

I was grateful to soak up some sunshine this evening since clouds and rain are expected this weekend in New Brunswick. 

Environment Canada says a low pressure system from the Great Lakes will bring a prolonged period of rain to the province. 

Highest amounts could fall in the southwest with up to 100 mm and possibly 50 mm for Greater Moncton. 

The emergency measures organization is warning residents living near the St. John River and its tributaries to be on alert for flooding. 

April 2017 – Spring sputters

Spring seldom arrives on time in New Brunswick and this year is no exception even though April was actually warmer than normal in Greater Moncton.

The month can be broken into four segments – cold in the beginning, then warm, turning cold again and finally warm again near the end.

A consistent snow cover began on 27 November and disappeared briefly in late January before finally melting for the season by 10 April.

Precipitation overall was below average with much less snow than normal.

Keeping an eye on N.B. rivers

Ice jam on Middle River causes flooding, 16 April 2016 (NB-EMO)

Emergency measures officials with River Watch in New Brunswick are closely monitoring the St. John River and say the only area currently above flood stage is near Jemseg.

Even with rain being forecasted by Environment Canada, water levels are expected to remain below flood stage for the rest of the week.

So far this spring, it has been relatively quiet along flood-prone areas of the St. John River system.

Along the Middle River, south of Bathurst, an ice jam created localized flooding and forced a road closure but water levels are receding.

Spring may finally arrive in N.B.

Snow finally melting in NE Moncton, 05 April 2017 (Dearing)


Good news… spring may finally be arriving!

Environment Canada says the recent winter-like grip over Southeast New Brunswick will finally give way to milder temperatures and rain beginning later this week.

Temperatures will finally climb into the double digits Celsius by Friday for the first time since 01 March!

Localized flooding is possible over ground which may still be frozen and in areas with a significant snow cover.

Another sign of a change in seasons is the return of many migratory birds in Greater Moncton this week with chirping sounds not heard in months.

Winter won’t let go!

Still looks like winter in NE Moncton, 31 March 2017 (Dearing)

The temperature was warmer in the far north cities of Whitehorse and Yellowknife than it was in Greater Moncton.

The thermometer barely climbed above freezing today but at least the sun made an appearance after a five day absence.

Lots of cloud and frequent periods of snow have made the end of March look more like the beginning of January.

Environment Canada is not forecasting spring-like weather in the near future with another possible snowstorm by the middle of next week.

Cold start to spring

The first week of spring has felt more like the dead of winter in Southeast New Brunswick.

Greater Moncton may have missed the brunt of two storms this week but extreme cold settled in behind them with a frigid -13.7 C on 23 March.

Half of the days so far this March have recorded well below freezing average temperatures.

Environment Canada is forecasting more chilly weather for the upcoming final week with even a chance of accumulating snow.
