Get the shovels ready as another wallop of snow is forecast to fall Tuesday night in London and its surrounding counties.

According to Environment Canada, a developing low pressure system is starting in southern United States and will arrive in southwestern Ontario on Tuesday evening.

Roughly five to 10 cm of snowfall is expected by Wednesday’s morning commute. The weather authority is asking commuters to allow some extra time during their drive.

Environment Canada has also issued a snowfall warning for Windsor-Essex and Chatham-Kent as well as Norfolk and Brant County where total snowfall amoungs of 15 to 20 cm are likely.

Areas closer to the Niagara Region are also under a warning and could see more than 20 cm before the snow tapers off later Wednesday.

Concerns about snowbanks

Meanwhile police are warning that the height of snowbanks in parts of Ontario are starting to impact driver safety and motorists should be extra cautious.

London police Const. Ken Steeves says "If the snowbanks are prohibiting your view or restricting your view by all means we suggest maybe reducing the height of them, put the snow in another location, just ensure the safety of yourself as well as other motorists."

OPP are also asking parents to talk to their children about the dangers of playing on or tunnelling under snowbanks.
