Strong fall storm coming

An intense low pressure system is heading to the Maritimes.

Heavy rain will start during the morning hours in Greater Moncton and strong winds will develop by midday.

Environment Canada says rainfall amounts could reach 50 mm while easterly wind gusts of 70 km/h or higher are likely.

Some trees may be at risk of falling after being weakened by Hurricane Dorian last month.

Many leaves will undoubtedly drop which could plug storm drains causing localized flooding.

Fall foliage past peak

The turkey dinner has been eaten and the leaves are now past peak in the region.

Fall foliage typically reaches its peak colour by the Thanksgiving weekend in Southeast New Brunswick.

While some trees still have most of their leaves, others are already bare.

Since Thanksgiving was 14 October – the latest possible date for the holiday on the calendar – peak colour actually occurred last week.

Strong, gusty winds normally bring down the rest of the leaves each year and… guess what?

Environment Canada has issued a special weather statement for Greater Moncton with a storm approaching Thursday bringing about 40 mm of rain and winds gusting up to 70 km/h.

Manitoba declares state of emergency

The Manitoba government declared a state of emergency on Saturday after a powerful storm dumped heavy rain, freezing rain, snow and wind to southern portions of the province this week.

Amid the early winter blast, Manitoba Hydro is trying to restore electricity to thousands of residents after numerous trees and branches – many still covered in leaves – fell onto power lines with winds gusting up to 100 km/h.

The storm was so bad it forced the temporary closure of the Trans Canada Highway from Winnipeg to the Saskatchewan border.

Southern Manitoba got blasted after a Colorado Low moved in from the United States where it brought dramatic temperature drops and heavy snow to the Great Plains states.

The next concern for local emergency measures officials will be flooding as the snow melts given the rising temperatures forecasted over the next few days.

Snowfall totals as of 1pm CDT on Saturday, October 12th:

  • Carberry  74 cm
  • Morden  64 cm
  • Winnipeg  34 cm
  • Dauphin  30 cm
  • Brandon  29 cm

Warmth returns!

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.

Coolest day since May

Irishtown Nature Park, 05 October 2019 (Dearing)

Chilly temperatures across the Maritimes on Friday made it feel more like early November than early October.

In Greater Moncton, the daytime high for 04 October was only 8.2 C which means it was the coolest day since 22 May when the maximum was only 8.6 C.

Halifax, Charlottetown, Saint John and Fredericton also had highs below 10 C.

The normal high for the first week of October in Southeast New Brunswick is 15 C with an overnight low of 4 C.

September 2019 – Dorian’s fury

Hurricane Dorian defined September for Southeast New Brunswick, Prince Edward Island and Nova Scotia.

Although downgraded before making landfall near Halifax, Dorian was still a very destructive storm.

Powerful winds toppled century-old trees onto power lines, a month’s worth of rain drenched the region in hours and a vicious storm surge tossed boats around like toys.

If it hadn’t been for Dorian, the month would have been quite dry in Greater Moncton.

September also lacked heat with slightly below normal temperatures thanks to chilly nights and cool daytime highs which often struggled to reach 20°C.

Autumn began just a few days ago but it already looks and feels like winter in parts of British Columbia, Alberta and Saskatchewan.

A strong low pressure system prompted snowfall and winter storm warnings as up to 100 cm of snow fell across southern Alberta.

Gusty winds behind the system created blowing and drifting snow making highway travel treacherous.

Many early season snowfall records have been broken.

Snowfall amounts (in cm) as of 1pm MDT, 30 September:

  • Calgary 32
  • Claresholm  40-45
  • Lethbridge  50-60
  • Taber  60
  • Cardston area  70-90
  • Waterton Park  95
