Alerts for: Metro Montréal - Laval

Warnings

3:00 PM EST Monday 22 December 2014
Freezing rain warning in effect for:

  • Châteauguay - La Prairie area
  • Laval area
  • Longueuil - Varennes area
  • Montréal Island area

Ice build-up due to freezing rain is expected or occurring.

A low pressure system developing over the Central United States will intensify as it heads toward the Great Lakes. A strong southerly flow will set up over the eastern part of the continent bringing a mild and humid air mass over the province of Quebec.

Tuesday, a mixed bag of precipitation will develop over the southern part of the province. A fairly long period of freezing rain is expected over the St Lawrence and Ottawa valleys. Despite the arrival of a milder air mass, persistent northeast winds will feed an influx of cold air near the surface, creating conditions favourable for freezing on exposed surfaces. However, ice accumulations should be between 2 and 5 mm.

Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous. Take extra care when walking or driving in affected areas.

Freezing Rain Warnings are issued when rain falling in sub-zero temperatures creates ice build-up and icy surfaces.

Environment Canada meteorologists will update alerts as required. Please continue to monitor your local media or Weatheradio for further updates. If you would like to report severe weather, you can call 1-800-361-0233 or send an email to tempsviolent.quebec@ec.gc.ca. You may also tweet reports of severe weather to #meteoqc.

A stormy holiday season.



A storm will hit Eastern Canada from December 23 to 25. The low

Intensify over the Great Lakes area during the next few days.
A strong southerly flow will set up over the eastern part of the
Continent, bringing a mild air mass over Quebec and the Maritimes.



On Tuesday the 23rd, a mixed bag of precipitation will begin to fall
Over Southern Quebec. Snow will be followed by rain, but there is a
Chance of freezing rain during the transition. In the St Lawrence

Warnings have been issued accordingly.



This first impulse will spread toward Eastern Quebec on December 24,
Bringing snow and freezing rain with it. During this time, western
Quebec will see some rain.



On Christmas Eve, a second, larger impulse will move into western

Be possible. Total rainfall amounts could be upwards of 25
Millimetres. However, areas near Labrador will see a snowstorm.
