Ice conditions are being monitored throughout the province.
Ice remains intact on much of the Red and Assiniboine rivers but warmer temperatures forecast for next week will influence ice breakup.

- be watchful of local waterways as flood conditions can develop quickly and ice conditions may be unsafe;
- avoid crossing areas with broken ice and surface water, and not drive or walk through fast moving water; and
- call 511 to check road conditions before travelling.
