Major flood risk remains for Red, lower Assiniboine and other southern Manitoba rivers

Provincial flood forecasters say they will be watching the weather closely over the next two months because the presence or absence of precipitation will determine the degree of flooding.

And then the rains came. This winter is on track to become Northern California’s soggiest on record. A key precipitation index is running more than a month ahead of the previous record pace, set in the winter of 1982–1983 (records go back to 1895).
