A significant low pressure system emerged out of the Southern U.S. and tracked southeast of the Lower Great Lakes Monday night bringing snow and blowing snow to Southern Ontario.
Many school buses were cancelled and some school were closed.
The highest snowfall totals were observed in the Hamilton and Niagara areas where extensive blowing snow made travel extremely hazardous. Exact amounts in the St. Catharines area are a bit uncertain, but there is an unconfirmed report of over 40 cm of total snowfall accumulation. Locally higher snowfall accumulations were also noted over the higher terrain south of Georgian Bay.
