Snow squall warning

WEATHER ALERTS
ENVIRONMENT CANADA
********************************
Weather advisory in effect for:
    •    Guelph - Erin - Southern Wellington County

A winter weather travel advisory is in effect.

Hazards:
Brief heavy snowfall with quick accumulations near 2 to 4 cm.
Very poor visibility in heavy snow and blowing snow.

Timing:
This afternoon and ending by early evening.

Discussion:
A sharp cold front is expected to move south through the area this afternoon. A narrow band of heavy flurries combined with gusty northwest winds associated with the front will lead to a relatively short but sudden drop in visibility. The front and associated band of heavy snow is expected to clear the region later in the afternoon or early evening.

Significant impacts on the afternoon commute are possible.

Travel may be hazardous due to sudden changes in the weather. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.

Be prepared to adjust your driving with changing road conditions.

********************************
Snow squall warning in effect for:
    •    Kitchener - Cambridge - Region of Waterloo
    •    Mount Forest - Arthur - Northern Wellington County

Conditions are favourable for a brief frontal snow squall today followed by lake effect snow squalls later today into Thursday.

Hazards:
Locally heavy snowfall with total accumulations of 15 to 35 cm possible.
Peak snowfall rates of 3 to 5 cm per hour.
Significantly reduced visibility in heavy snow and blowing snow.

Timing:
Beginning this morning or afternoon, and ending Thursday afternoon.

Discussion:
A sharp cold front is expected to move south through the area today leading to the development of a frontal snow squall. Heavy flurries associated with the cold front combined with northwest winds gusting up to 70 km/h will cause a sudden drop in visibility to near zero.

Behind this front, lake effect snow squalls off Lake Huron and Georgian Bay will develop this afternoon or evening and persist into Thursday afternoon. Strong northwesterly winds along with the lake effect snow squalls will lead to significantly reduced visibility in blowing snow.

Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Rapidly accumulating snow could make travel difficult over some locations.

Consider postponing non-essential travel until conditions improve.
