Canadian Coast Guard Dispatched Amid Flood Concerns

Canadian Coast Guard vessel Griffon has been dispatched to Lake Erie and the mouth of the Grand River amid flooding concerns.

The CCGS Griffon will be breaking up ice jams near Port Maitland, ON and the mouth of the Grand River today, where is connects to Lake Erie. This is an effort to reduce flood risk due to ice restriction of water as it passes down stream today through Wednesday.

Communities along the Grand River and its tributaries should pay close attention to local statements and updated warnings from the Conservation Authority. A flood warning remains in effect for the entire watershed.

The flood concern is expected to peak Wednesday morning, before cooler temperatures and mixed precipitation arrives.

Total rainfall amounts of 40-60mm is expected. Locally higher amounts are expected east of Lake Huron.

Drenching Rain for Southern Ontario: Localized Flooding

[UPDATED]

A series of moisture-laden impulse waves that will provide a strangle-hold through the Southern and Central USA states will push Northeastwards across Southern Ontario beginning Monday and linger through Wednesday.

Several days of moderate rainfall will tally up the precipitation totals to respectable amounts.

Due to many regions still having a more than measurable snow depth, localized flooding will be a widespread concern.

Is it all bad news? Absolutely not! Warm temperatures will surge through much of the aforementioned regions and potentially ‘tickle’ record-breaking on Tuesday as temperatures surpass the teens.

What’s to come afterwards? Temperatures will cool off, however, there is no significant frigid or arctic air in the forecast until at-least March, and confidence and certainty is somewhat low at this time.

New Brunswick

Treacherous Conditions for Quebec and New Brunswick

Respectable ice accretion is expected to build for parts of Quebec and West-Central regions of New Brunswick.

Freezing rain is expected to creep through both of the aforementioned provinces and pose an extended threat of widespread freezing rain. While not all regions are expected to be targeted, regions such as Quebec City and its Northern suburbs, as well as, regions in West-Central New Brunswick will become treacherous as upwards of 15mm of accretion could result. Regions elsewhere will receive minimal accretion, and thereby, only isolated and patchy icy conditions will be present.

Freezing rain is expected to linger into much of the day on Tuesday.

Predominantly rain will target Southern New Brunswick, and Eastern PEI.

At TransCanada Weather, we suggest you take extra care while walking outside or commuting to and from work.

Please adjust your driving habits accordingly and be prepared to allot extra time from traveling to and from your destination.

Manitoba

Dangerous Windchills for Manitoba and NW Ontario

A brief period of dangerous and life-threatening Windchills are inevitable across Central and Northern Manitoba, as well as, Northwestern Ontario.

A fierce Arctic air-mass will funnel extremely cold air from ‘way-up’ in Northern Canada down to the aforementioned regions.

Parts of Central Manitoba could experience Windchills hovering near -60C. Elsewhere, Windchills in the -50 to -55C range are probable.

It is extremely important residents bundle-up all exposed skin as frostbite can occur in under 2 minutes in these uninhabitable conditions.

Soaking Rain For Ontario and Quebec

A series of moisture-laden impulse waves that will provide a strangle-hold through the Southern and Central USA states will push Northeastwards across Southern Ontario, Eastern Ontario and Southern Quebec beginning Monday and lingering into Thursday.

Several days of moderate rainfall will tally up the precipitation totals to respectable amounts; ranging from 20-80mm based on the location as depicted on our map.

Due to many regions still having a more than measurable snow depth, localized flooding will be a widespread concern, particularly across ‘Cottage Country’, Eastern Ontario and Southern Quebec.
For regions across Southern Ontario, many regions are still dealing with isolated and ‘patchy’ ice from last weekends ice accretion: watch for localized pooling.

While some models are suggesting 100-125mm is possible over a ~60 hour interval for some regions near Lake Huron and Lake Erie, this is likely a slight over-achievement and we expect the upper threshold of totals to be more in-line with 80mm, with many populated locales receiving 40-65mm.

Is it all bad news? Absolutely not! Warm temperatures will surge through much of the aforementioned regions and potentially ‘tickle’ record-breaking on Tuesday as temperatures surpass the teens.

What’s to come afterwards? Temperatures will cool off, however, there is no significant frigid or arctic air in the forecast until at-least March, and confidence and certainty is somewhat low at this time.
