Major Storm for parts of Central and Eastern Canada


July 13, 2010 — Snow ending across Eastern Ontario and Southern Quebec this morning. Snowsqualls plaguing Southern Ontario through this afternoon. Strong winds easing later today for the Maritimes, Quebec, and Ontario.

The large fall storm that continues to affect much of Central and Eastern Canada will slowly wind down later today. However, snowsqualls will continue to cause problems across Southern Ontario and strong winds will be slow to ease through the Maritimes. Here is a regional breakdown of the weather yet to come with this powerful system.

Eastern Ontario and Southern Quebec: Snow ending but strong winds and poor travelling conditions persist

Heavy wet snow has fallen through the overnight hours across Eastern Ontario from the Ottawa to St. Lawrence Valleys. While the snow will diminish through Wednesday morning, wind and cold temperatures will make for locally icy roads.

Montreal narrowly avoided the heavier accumulations, but areas from Mt. Tremblant through Ottawa to Gananoque have seen significant snowfall.

Southern Ontario: Snowsqualls continue today with local whiteout conditions

Lake-effect snowsqualls and strong winds will create locally dangerous driving conditions through today before winding down tonight. While some areas will escape with barely a flurry, more than 15 cm of snow is possible in the heaviest bands off Lake Huron and Georgian Bay.

Squall bands from Lake Huron will continue to impact the traditional Snow Belt regions near London. Road conditions through Grey, Bruce, Huron, Perth, Middlesex and Oxford counties will be poor with local whiteouts. Highway 401 will be affected by these squalls and travel will be treacherous as conditions change rapidly.

Snowsqualls off Georgian Bay will make travel hazardous on Highway 400 between Barrie and Vaughan. These snow bands could give accumulating snow as far south as Markham, Scarborough and Pickering. While areas from Hamilton to Mississauga should avoid the squalls, commuters on the northeast side of the GTA York Region especially will be dealing with the first significant snow of the season. Accidents are likely as conditions will deteriorate rapidly when driving through these squalls. The lake-effect snow will diminish Wednesday night with a warm up in store by Halloween.

Maritimes: Strong Winds easing later today

Strong southerly winds locally gusting over 100 km/h through the morning hours will begin to abate this afternoon as the strong storm over Quebec begins to weaken and push north.
