October 2019 – Gradual easing into fall

Centennial Park, Moncton, 14 Oct 2019 (Dearing)

Daytime highs were consistently in the mid-teens in Southeast New Brunswick during October which usually sees a sharp drop in temperature as the month progresses.

The average temperature was 0.7°C above normal in Greater Moncton with two days failing to reach 10°C and the warmest maximum on the last day, 19.3°C.

Six days had lows below freezing with some light frost but there was no hard freeze allowing vegetation to flourish.

The precipitation total mostly came from five rainfall events with not a single snowflake recorded.

Fall foliage peaked prior to Thanksgiving weekend and several strong wind events left few leaves on trees by Halloween night.

A Blustery Halloween!

Fallen leaves, Centennial Park, Moncton, 14 Oct 2019 (Dearing)

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.

Fading tropical storm batters Ontario

The remnants of Tropical Storm Olga were felt across Southern Ontario on the weekend with rainy and windy conditions.

Environment Canada says between 30 and 60 mm of rain fell across the region including the Greater Toronto Area.

Wind gusts were up to 80 km/h in some locations with a peak of 104 km/h recorded at Port Colborne on Lake Erie.

Olga formed in the Gulf of Mexico several days ago and made landfall in Louisiana before quickly churning northward toward the Great Lakes.

Forecasters are calling for more wet weather and cooler conditions by Halloween.

More rain & wind for Maritimes

Another low pressure system moved through the Maritimes on Wednesday bringing a lot of rain to the region especially to western New Brunswick.

Winds were also a factor with this storm but for a shorter period of time even though the peak gust was 81 km/h which was slightly higher than last week.

Here some rainfall totals (mm):

  • Saint John  59
  • Edmundston  59
  • Bathurst  49
  • Fredericton  48
  • Miramichi  37
  • Sydney  30
  • Charlottetown  22
  • Halifax Stanfield Airport  21
  • Greater Moncton  19

Fast and furious storm

A so-called bomb cyclone with wind and rain moved through the Maritimes in just a few hours today.

The intense low pressure system brought winds gusting up to 89 km/h in Saint John which uprooted some trees already weakened by Hurricane Dorian last month.

Greater Moncton recorded a peak gust of 78 km/h along with 20 mm of rain which caused some localized flooding as leaves clogged storm drains.

The winds were even stronger in Nova Scotia with a gust of 101 km/h at Halifax harbour and 106 km/h in Lunenburg which brought trees down knocking out power.

The highest gust was near Cheticamp on Cape Breton Island at 148 km/h.

Rainfall amounts across New Brunswick and Prince Edward Island ranged from 15 to 30 mm with more than double those amounts in Nova Scotia.

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.
