Heavy wet snow results in widespread power outages across Southern Quebec

Hydro-Quebec is dealing with a significant number of outages on Tuesday morning as a result of heavy wet snow. Over 377,000 customers are without power across the province, the majority here in the southwest corner. Montreal alone is reporting over 41,000 in the dark. (Hydro-Quebec)

Between 10-20cm of snow fell across the Island of Montreal in under 6 hours.

As of 7AM Tuesday, 375,00 Hydro-Quebec customers have no power.

Roads are snow covered, icy and dangerous - some school are closed for the day.

The upper level low responsible for our winter-like weather on Sunday, spawned a weak surface low over Vermont that moved north late Monday, providing enough lift to produce heavy wet snow across the extreme southwestern corner of Quebec. In under 6 hours, over 10cm of heavy wet snow fell, weighing down trees, many which still have leaves on them, onto power lines.

A narrow band of heavy wet snow developed on the backside of this past weekends storm, dumping a quick 10-20cm of heavy wet snow from Plattsburgh and Burlington north into Montreal. The snow caught many by surprise resulting in scores of accidents during the Monday evening commute. (Valley Weather)

The result has been widespread power outages, with Hydro-Quebec reporting over 1000 individual breaks in the system, with 377,620 customers without power as of 7am Tuesday morning. That includes 41,820 on the Island of Montreal and 19,496 in Laval. The utility has responded with crews, but strong winds and continued snowfall are slowing down the recovery operation.

In Montreal, the snow resulted in very dangerous travel conditions, with a rash of accidents reported during the evening hours. Travel remains very poor Tuesday morning, with many roads snow covered, with hard packed snow and ice on many secondary roads. Travel with great caution and remain off the roads if you do not have winter tires on.

The same system continues to push waves of light snow across Southern Quebec Tuesday morning, with another 2 to 4cm possible today. Winds will be gusty from the northwest at 30-50km/h, and temperatures will remain cold for Remembrance Day, around -2C (29F). If you have plans to attend a service, dress warmly.

Wintry weather causes accidents and power outages in the Montreal region

Seven hours of freezing rain coated trees and power lines in parts of Montreal on Sunday. More than 14,000 Hydro-Quebec customers were left without power. (Valley Weather Photo)

A messy mix of snow and freezing rain moved across southern Ontario and Quebec on Sunday, as the first winter storm of the season moved from Ohio into Maine. Montreal was right on the snow/rain line, with a few hours of snow to start, followed by 7 hours of freezing rain.

The mixed bag of precipitation took a toll on roads and power lines. Several major crashes occurred, including one on Highway 19 involving 20 cars. Others were reported on the west end of the island, where anything elevated become iced over quickly during the afternoon hours.

Power lines and trees were coated in ice as well, this was especially true right along the St. Lawrence River. Outages totalled close to 15,000 at the height of the storm, that number is down to 9,500 Monday morning. Most involve trees coming in contact with wires.

In Montreal the mercury sat right around the freezing point, with around 10mm of freezing rain falling and 1-3cm of wet snow, depending on your exact location. Further north and west, it was all snow. Ottawa reported 12cm, while Roberval, north of Montreal measured 15cm. Winds gusted well over 60km/h at times, making for a real raw November day.

More snow fell in Ottawa, with 12cm observed. Roads were slick in eastern Ontario, with hundreds of accidents reported. (Photo: 613Wrecked)

In Ontario, hundreds of accidents were reported by the OPP along both highways 401 and 417. Most of Ontario reported mainly snow, with the exception of a narrow sliver along the Saint Lawrence River from Kingston to Cornwall.

The weather will continue to be winter like this week, with significant lake effect snow expected south and east of the Great Lakes. Here in southern Quebec, expect flurries off and on through Tuesday evening, along with moderate northwest winds to 50km/h. Snow may accumulate locally 2-4cm, especially if we tap into some Great Lakes moisture.

Temperatures will fall on Monday below freezing again, down to -2C (29F) Tuesday morning and remain stationary all day. The weather will remain unsettled all week, with a mix of rain and snow froecast for Wednesday. Amounts should be on the light side, but expect slick spots when driving.

Have those winter tires installed and please use common sense and courtesy and clean the ice and snow off your car. I noticed on my Monday morning commute, ice flying off several vehicles and striking others. Please take a few minutes and clean your vehicle.

The 50th Anniversary of the wreck of the Edmund Fitzgerald - November 10

The wind in the wires made a tattle-tale sound
And a wave broke over the railing
And every man knew, as the captain did too,
T'was the witch of November come stealin'.

It was 50 years ago on November 10, 1975 at approximately 7:20 pm that the iron ore carrier Edmund Fitzgerald went down in a fierce fall storm on Lake Superior. While weather played a definite role, the exact details of the sinking of the ship remain a mystery today. The ship went down quickly, with very little warning or Mayday, taking 29 lives with her. The sinking was caused in part by a strong November Gale or "November Witch". Oddly enough on this 50th Anniversary, we have a similar but weaker storm heading from the Ohio Valley towards the Great Lakes over the next 48 hours. A gale warning is in effect for parts of the region, with the system expected to produce rough waters, strong winds, lake effect snow and rain.

The mangled lifeboat was recovered shortly after the sinking, showing the power of the wind and waves that night. The exact cause of the sinking remains a mystery still today 50 years later. (mghd.org)

The 1975 storm was as intense as they come with 20 foot waves on Lake Superior and winds gusting well over 50 knots. The severe weather was confined to an area along the immediate trajectory of the storm, and especially rough in the waters of eastern Lake Superior, exactly where the Edmund Fitzgerald was. It was a case of the wrong place at exactly the wrong time. The storm was known as a November Witch and classified as a weather bomb, with rapidly dropping pressure from 1000mb over Kansas to 978mb over James Bay in less than 24 hours. The rapid intensification and speed of the storm caught the ship and its crew almost without warning. 

Several memorial services are planned each year including the annual event at Whitefish Point, Michigan, not far from the final resting place of the majestic ship and her crew of 29 brave men. The bell from the Edmund Fitzgerald was recovered in 1995 and has been rung 30 times each year at Whitefish Point on the anniversary of her sinking. This represents all 29 men on board as well as the many others who have perished on Lake Superior. The ship sits in 162 metres (about 530 feet) of water just inside the Canadian boundary, 17 miles north of Whitefish Point, Michigan in Lake Superior.

The wreck has been investigated on at least 30 dives, but none since 1995. Ocean explorer Jean-Michel Cousteau, the son of the late Jacques Cousteau became the first person to lay eyes on the ship in 1980. "The ship was amazingly beautiful because it's deep and cold and nothing's growing on it or very little," he said. Dives to the ship were suspended in 1995 after the bell was recovered by the Canadian Navy and the Great Lakes Shipwreck Museum. The wreck is now considered a protected gravesite and no further permits have been issued by the Canadian Government in the last 30 years.

The exact cause of the sinking of the great Edmund Fitzgerald remains a hotly debated mystery still today, 50 years later. Some think the ship struck bottom near Caribou Island and began taking on water. Others think a massive roque wave drove her straight to the bottom of Lake Superior where she rests in a matter of minutes. Still others say the ship broke in two from constant wear over the lifespan of the ship, which dated back to June 7, 1958.

The Edmund Fitzgerald had left Superior, Wisconsin late in the day on November 9th, 1975 with a cargo of 26,116 tons of taconite pellets on her way to Detroit. There are a series of photos, information and very chilling radio chatter from 1975 at www.shipwreckmuseum.com

Snowfall Warning for Montreal

The first significant snow of the season will arrive on Sunday, with 10 to 20cm possible from Montreal north and west into the Ottawa Valley and the Laurentians. Travel will be difficult at best.

Snowfall Warning in effect for metro Montreal, eastern Ontario and the Ottawa Valley for Sunday.

The first significant snowfall of the season is expected Sunday into Monday across portions of southern Ontario into southwestern Quebec. Low pressure will move down the St. Lawrence Valley on Sunday and east of Montreal into New England on Monday.

The warmer temperatures of early Saturday are gone for at least the next week if not longer. Montreal reached 10C (50F) during the overnight hours as a warm front lifted across the region. That was quickly followed by a cold front, gusty northwest winds, flurries and dropping temperatures for most of Saturday. Overnight lows by Sunday morning will be near -1C (30F) and remain nearly stationary all day Sunday.

Snow will overspread the region Sunday morning, possibly mixed with freezing rain or rain south of the St. Lawrence River, with all snow north of the valley. Expect 5 to 10cm of snow on Sunday in Montreal, with an additional 5 to 10cm by Monday morning. Roads will become snow covered and slippery.  Northeast winds of 20-40km/h will make it feel even colder, and lower visibilities in steady snow. This will be a shock for many, as Montreal has barely had a snowflake or any frost so far this fall.

Driving conditions will become very poor on area highways, especially as this is the first snow of the season, and most drivers are not prepared. Leave the car at home if you do not have winter tires installed. Consider changing travel plans if possible and perhaps working from home on Monday.

Colder air will filter in behind the low Sunday night, changing any mixed precipitation back to all snow. Temperatures will remain at or below 0C (32F) throughout Monday. The week ahead will remain unsettled and cold with more flurries possible through Wednesday.

First snowflakes of the season on the horizon for Montreal

Snow has already fallen this week in spots across the Eastern Townships into the White mountains of New Hampshire and parts of Vermont. More snow is expected through Monday, with locations like Jay Peak, Vermont picking up as much as 20cm. Snow may also fall in the valley locations by Sunday night, including Montreal. (NHDOT Photo)

Measurable snow is possible by late Sunday into Monday morning for parts of southern Quebec.

First of all, if you do not have your snow tires on yet, now is the time to seriously consider doing so. Our weather will turn unseasonably cold over the next week, while a series of clipper systems moves southeast across Ontario and into New England. This will produce enough cold air for some snow to fall. While this will not be a big storm, the first snow of the season in any form usually sparks panic on the roads. Be ready!

Alberta Clippers are weaker areas of low pressure that develop in the southern Prairies and move rather quickly east across Ontario and Quebec. They often gain a little strength when the waters of the Great Lakes have yet to freeze. Clippers usually have limited moisture, so they are not our big storms, but they do produce squally weather, strong winds and a sharp drop in the temperatures on the back side of the systems.

November has already produced more seasonable weather in Montreal, after a warm September and October. Snow may fall next week across parts of southern Quebec. (Valley Weather Photo)

We have three such systems forecast to move across our region through Monday. The first on Wednesday, will produce showers and gusty west winds. Wind speeds may top 60km/h in the St. Lawrence Valley. Temperatures will only reach 6C (43F) for a high, followed by morning lows close to the freezing point. On Thursday, behind the first clipper, temperatures will hold steady at 2C (36F), along with blustery conditions and perhaps a snowflake or two. The chilly air will persist into Friday.

Another clipper late Friday, will pass north of Montreal, allowing some warm air to briefly enter the forecast. After a cold morning, highs will reach 8C (47F) on Saturday. On Sunday, the strongest of the three clippers will move south of Montreal, dragging a potent cold front behind it. Temperature will fall to below freezing Sunday night as the coldest air of the season to date arrives across Ontario and Quebec.

Any rain Sunday will change to wet snow overnight into Monday morning across the Ottawa Valley and into Montreal, with a slushy centimetre or two possible for many locations. Temperatures will drop below freezing Sunday night and likely remain near 0C (32F) for highs on Monday. Tuesday will remain breezy and cold, with flurries and a high near 2C (36F).

By the way, how cold is the air over Northern Canada? On Wednesday morning as I write this post, Eureka, Nunavut is -37.6C.

Windy, wet and chilly Halloween in Montreal

It is looking like a wet, dark and chilly Halloween night in Montreal, along with blustery winds up to 60km/h. We may see a break in the heavier rain for the kids to trick or treat, but I think conditions will still be wet and cold throughout the evening. Warm costumes, umbrellas and bright colours are in order, stay safe and have fun!

Happy Halloween

Heavy rainfall warning remains in effect for southern Quebec.

The weather will be damp, windy and chilly for Trick or Treating in Montreal this Halloween.

Deep low pressure moving across upstate New York along with a second storm system developing along the Atlantic coast, will produce lots of rain across southern Quebec for Halloween. Waves of moisture have brought 30 to 40mm to Montreal already since Thursday morning, with another 20 to 30mm expected Friday. 

The rain will be heavy at times, as it has been during the Friday morning commute in Montreal. Visibility is down to a few kilometres at best in heavy rain, making for slow travel, along with numerous accidents on rain slicked roads. Some minor flooding has been reported as well, especially in areas with poor drainage or leaves blocking the sewers.

As the low pressure moves to our east, the gusty northeast winds will back to the west and increase 40-70km/h at times. Temperatures will drop from our current highs near 9C (48F), down into the low single digits, around 3C (38F) tonight. The steady rain will taper to showers this evening. 

As colder air moves into the region, the rain may change to a period of snow across the higher elevations, with perhaps a flake or two in the valley locations by Saturday morning. On Saturday, expect a chilly high of 6C (43F), along with blustery northwest winds of 30-50km/h and cloudy skies. High pressure will try to clear the skies out for Municipal Election Day Sunday, but I think partly to mostly cloudy skies should prevail, along with a high of only 6C (43F).

Heavy rainfall warning issued for southern Quebec

Widespread heavy rainfall warnings have been issued for southern Quebec and eastern Ontario, with 40-70mm forecast. Deepening low pressure will move from the Ohio Valley into southern New England today, while a secondary low develops along the middle Atlantic coast. That low will draw in some moisture form hurricane Melissa as it travels between Bermuda and the offshore waters of Atlantic Canada. The heavy rain may cause some minor flooding issues, especially where falling leaves are blocking sewers and gutters.

Rainfall from the first low has already arrived in Montreal Thursday morning, and should fall throughout most of the day. Overnight into Friday morning, additional moisture will arrive from the southeast, with localized heavy rain possible. Winds will increase from the northeast Thursday 20-40km/h, backing to the northwest Friday afternoon, and increasing to 30-50km/h. The cool, damp and breezy weather will make for a rather challenging Halloween in Montreal. I still think that the weather may break for Trick or Treating, with more showery conditions opposed to heavy rain.

Regardless of the precipitation falling, the weather will dark, windy and downright spooky. Temperatures will be chilly, in the 5C to 9C (41F to 49F) range throughout the forecast period and into the weekend. There may even be a few snowflakes on Halloween night as much cooler air moves in behind the departing low. They will most likely be confined to the higher elevations, but I would not be surprised to see a flake or two around Montreal into Saturday morning.

Skies will finally clear by Sunday as high pressure settles into the region.
