Winter Storm Warning

Issued at 16:00 Saturday 19 January 2019

Winter storm conditions will continue tonight.

Snow at times heavy and blowing snow will continue this evening and begin to taper off late tonight or early Sunday morning.

Although the storm system responsible is tracking well to the south of the Great Lakes, northeast winds off Lake Ontario are picking up extra moisture resulting in higher snowfall totals.

Winds are forecast to gradually begin to shift to a more north to northeasterly direction late this evening. As a result, the very heavy snow near the western end of Lake Ontario will diminish somewhat toward midnight. However, conditions will likely worsen for a period tonight over much of Niagara region.

Additional snowfall accumulations of 10 to 15 cm are expected. Locally higher amounts of 20 cm are possible. Amounts will be considerably less for areas north of Hamilton and Burlington

In addition, strong winds gusting to 60 km/h will generate widespread blowing snow and cold wind chill values in the minus twenties. Near zero visibility is likely at times.

###

Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@canada.ca or tweet reports using #ONStorm.
