New Brunswick's Emergency Measures Organization has issued a localized flood advisory for the province.
In a statement released on Wednesday, EMO officials say rivers, streams and tributaries "are not frozen as they would normally be this time of year," which could lead to some localized flooding.
In addition, EMO is warning people that it's not safe to cross any waterways on foot, by snowmobile or ATV, "because of the deterioration of ice covers."
Environment Canada is forecasting messy weather for Wednesday evening and into Thursday, with snow changing to ice pellets and freezing rain, then to rain as temperatures rise. Northern New Brunswick could see an extended period of freezing rain overnight, along with strong winds.
