About 150 flood-affected city property owners along Christie Road, Forbes Road, Kingston Row and Kingston Crescent will be served notice Wednesday evening.
Emergency preparedness co-ordinator Randy Hull said the chance of homes being evacuated remains low, but should it happen, they will have only a matter of hours to leave.
In a news release Wednesday afternoon, the City of Winnipeg urged property owners near the river to "remain vigilant as the potential for a rapid rise in river levels due to serious ice jams continues."
If river levels rise suddenly due to an ice jam, there is the potential that a temporary evacuation of specific areas may be required, the release stated.
Some of the ice jams that have plagued the city for the past couple of weeks began moving on Tuesday, between Bishop Grandin Boulevard and the Elm Park Bridge in south Winnipeg.
In other areas, the ice remains intact and will likely begin moving over the next few days, the city expects. Ice has begun moving into the floodway channel, where city crews are working to break it up as much as possible.
It is expected that ice will pass through the floodway and exit at the north end, then collide with the solid ice cover north of the city.
Water levels between the south Perimeter Bridge and the floodway entrance gates have already risen significantly since the floodway was activated, the release states.
When the floodway gates south of the city block the river flow through Winnipeg, they force the water to back up so it clears the elevated edge of the floodway channel and flows into the diversion.
Dike elevations at the south end of the city were set four feet above the forecast water level to account for that potential rise, as well as any increase from ice jams, the city said.
If any evacuations are necessary, they will be conducted through City of Winnipeg emergency services personnel. More information can be found on the city's EmergWeb (
