A special weather statement remained in place Wednesday afternoon calling for moderate to heavy snowfall to continue across southwestern Ontario into the evening hours.
The expected significant snowfall is thanks to a Texas low pressure system that arrived in the region earlier Wednesday, according to Environment Canada.
The system could bring up to 15 cm of snowfall by Thursday morning.
The same low pressure system has prompted flood watches in the region along Lake Erie and Lake Huron.
The Ausable Bayfield Conservation Authority (ABCA) said in a statement that expected strong winds with gusts exceeding 70km/h may result in flooding and erosion problems along the Lake Huron shoreline.
The conservation authority’s flood watch stretches from the Ipperwash area along the coast to just north of Bayfield, Ont.
A flood watch issued by the Lower Thames Conservation Authority Wednesday morning said gale warnings and freezing spray warnings had been issued by Environment Canada in its marine forecast for the Lower Great Lakes.
High winds are expected to begin Wednesday evening, lasting though Thursday and possibly into Friday, said the advisory, which spans an area running from the Port Stanley area west to Leamington.
“Thursday afternoon into Friday, there is the possibility of shoreline damage, erosion and/or flooding in areas such as Erie Shore Drive,” the advisory said, referring to the lakeside roadway located just south of Blenheim.
The Long Point Region Conservation Authority also issued its own flood watch for the Lake Erie shoreline Wednesday afternoon. It runs from the Port Stanley area east into Haldimand County.
Forecasts calls for westerly winds of 45-55 km/h and gusts up to 80 km/h starting Thursday morning and continuing into early Friday morning, the advisory said.
The incoming system brings a stark end to a string of mild and dry weather in the region. On Sunday, the temperature hit 9 C in Windsor and Sarnia, and 7 C in London.
On Wednesday, the daytime high was expected to be 0 C in all three cities.
