Flood warnings

The Emergency Measures Organization is advising people living near the province's rivers to be prepared for flooding. (CBC) The provincial government issued an alert on Tuesday afternoon that said the predicted temperatures and rainfall could see continued melting of the snow pack and the deterioration of ice covers.

“River flows are forecast to increase throughout the basin and there is a high probability of ice movement along the St. John River and other river systems across the province within the next two days,” according to an advisory released by the provincial government.

“With ice movement there is the potential for ice jams to occur as well as associated flooding. People living in all regions should be prepared and remain a safe distance away from waterways.
