September 2012 – Warm and wet

Fall colours near Elgin, NB (file)

September in Greater Moncton felt like a continuation of the incredible summer we had with one exception – it finally rained and when it did it poured.

After below normal amounts of rain in July and August, September certainly made up for it although for farmers it may have been too much too late.

Perhaps the warm, wet weather played a role but the leaves seemed slow in changing colour with only hints of red, yellow and gold by the end of the month.

Flowers still flourishing

A look at the flower beds in downtown Moncton today shows they are still flourshing despite this morning’s cool low of 2.0 C.

A frost warning was posted for much of New Brunswick overnight and although we escaped frost in my neighbourhood, light frost did occur in some low-lying parts of the region.

Frost warning

Environment Canada has issued the first frost warning of the season.

Coincidently, the average date of the first fall frost in Moncton is 27 September.

Frost warning for Moncton and Southeast New Brunswick

Clear skies and near zero temperatures will cause frost tonight.

A ridge of high pressure building in over New Brunswick today will bring clear skies and near zero temperatures tonight to much of the province, causing frost.

Autumn arrives

Autumn officially arrived at 11:49am today in the Atlantic Time Zone.

If you are lamenting the end of summer like I am, take comfort in the fact that Environment Canada says it was the warmest summer in Atlantic Canada in 65 years.

The weather office is predicting the warmth to continue this fall.

New Brunswick is expected to have a mild autumn with above normal temperatures and near normal precipitation.

Rainy end to summer

The warm, dry summer of 2012 in Greater Moncton is ending on a wet note.

Environment Canada is forecasting about 30 mm of rain for Southeast New Brunswick although some areas including Nova Scotia and Prince Edward Island could receive up to 60 mm.

A slow-moving low pressure system is to blame for the wet weather but the temperatures will be warm with highs in the low 20’s C for Saturday.

The precipitation is definitely not needed in water-logged areas like Truro, NS which has already picked up more than 200 mm of rain so far this month.

Leaves starting to change colour

More and more hints of colour are starting to appear on the trees these days in Southeast New Brunswick.

Summer is officially winding down this week and we are losing more daylight, today at 12 hours and 15 minutes.

Fall colours are typically at their peak in Greater Moncton in early to mid-October, usually around Thanksgiving.

Leslie lashes Newfoundland

Post-tropical storm Leslie touched down in Newfoundland today with hurricane-force winds on the province’s east coast and drenching rains in the west.

The Canadian Hurricane Centre says the centre of the storm made landfall in Fortune on the Burin Peninsula at around 8:30 am local time.

The potent storm buffeted areas around St. John’s with winds gusting up to 131 kilometres an hour, causing damage to roofs, roads and widespread power outages.

Waves reached 10 metres at an offshore buoy.

Schools were closed, many government offices shut down and airports cancelled flights.

Flooding in Truro

My hometown of Truro, NS has been inundated with floodwaters today thanks to heavy rain and a high tide which spilled the banks of the Salmon and North Rivers.

More than 100 mm of rain fell in the Truro area in just an 18 hour period.

Floodwaters breached two dikes which forced the high school, Cobequid Educational Centre, and the Stanfield’s plant to evacuate.

Numerous roads were closed and some were even washed out.

Residents of a low-lying mobile home park in neighbouring Bible Hill also had to be evacuated.

More rain is expected to fall as Hurricane Leslie brushes eastern Nova Scotia on its way to Newfoundland.

Nova Scotia and Newfoundland can expect heavy surf over the next few days ahead of Hurricane Leslie, a Category 1 storm which is currently churning slowly toward Bermuda.

Residents of the British territory were stocking up on emergency supplies today and tourists were cancelling holiday plans to the remote island.

The Canadian Hurricane Centre says Leslie could impact Atlantic Canada by Tuesday but its path is still uncertain.

Some models show Leslie making landfall in Cape Breton while others show it veering off to the northeast and being pushed back to the ocean by a high pressure system.

Here comes the rain!

In Southeast New Brunswick, we have waited almost the entire summer for a decent rainfall and it finally came today!

Environment Canada posted rainfall warning for virtually the entire province today as the remnants of Hurricane Isaac merged with a low pressure system to create a big downpour.

As much as 90 mm of rain was expected to fall in some areas which would surpass rainfall totals for July and August combined.

Some minor localized flooding was reported especially in Saint John and along the Fundy coast.

RAINFALL TOTALS, 05 Sept 2012

Moncton  64.6 mm (beats old record of 31.0 mm from 1966)

Saint John  107.7 mm (beats old record of 27.6 mm from 1988)
