Environnment Canada has issued a winter storm warning in effect for: Niagara Falls – Welland – Southern Niagara Region – St. Catharines – Grimsby – Northern Niagara Region for today and tonight.
Snow at times heavy and blowing snow are expected to develop early this morning and taper off overnight.
Although the storm system responsible will track well to the south of the Great Lakes, northeast winds off Lake Ontario will pick up extra moisture resulting in higher snowfall totals. Snowfall accumulations of 15 to 25 cm are expected. Snowfall amounts should be considerably less for areas north of Hamilton and Burlington.
In addition, strong northeast winds gusting to 60 km/h will generate widespread blowing snow and cold wind chill values near minus 20. Near zero visibility is likely at times.
Consider postponing non-essential travel until conditions improve. 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. Now the more detailed forecast:
