Discussion:
The first significant lake effect snow squalls of the season are forecast to begin this afternoon. These snow squalls will continue tonight before weakening late Tuesday.
Of particular concern is the potential development of a very intense band of lake effect snow tonight. If this band develops, it may produce intense snowfall rates of 5 to 10 cm per hour. The band is expected to meander somewhat, but if it locks in, some locations may receive significantly higher amounts.
Strong westerly winds followed by northwesterly winds will accompany these snow squalls resulting in significantly reduced visibility at times in heavy snow and 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. Road closures are possible.
Consider postponing non-essential travel until conditions improve.
Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or tweet reports using #ONStorm.
