UPDATE: Niagara Falls, Welland and the Southern Niagara Region are under a snow squall WARNING.
Snow squalls are expected to develop.
Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Snow squalls are expected to develop off Lake Erie this afternoon and end this evening. Local snow amounts of 10 to 15 cm are possible.
Travel may be hazardous due to sudden changes in the weather.
Visibility may be suddenly reduced at times in heavy snow.
Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow.
Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
