THUNDER BAY – Environment Canada has issued a Freezing Rain Warning for Thunder Bay and most of Northwestern Ontario. A low pressure system developing over Montana is tracking towards Northwestern Ontario. An associated band of freezing rain is expected to begin overnight over western sections and spread eastward early Tuesday morning. Several hours of freezing rain, at times mixed with ice pellets, are possible before temperatures rise above freezing and a change over to rain occurs.
Travellers should be prepared for poor conditions as untreated surfaces will become icy.
