Manitoba Transportation and Infrastructure’s Hydrologic Forecast Centre continues to monitor flood activity as an additional precipitation system is expected to move through the province. The precipitation is expected to continue through June 12, bringing significant rainfall to much of western, southern and eastern Manitoba including the Interlake region.
There is still considerable uncertainty across weather forecast models regarding the location, timing and amount of precipitation. However, there is higher confidence that areas in western Manitoba, including the Parkland region, and in southeastern Manitoba, including the Whiteshell lakes area, could see up to 70 mm of precipitation before the system leaves the province.
Most other areas of southern, eastern and central Manitoba, including the Interlake region, could receive between 30 and 50 mm of precipitation during this period. Some forecast models indicate the potential for thunderstorms to develop across portions of southern and southeastern Manitoba, which could result in localized rainfall amounts well over 70 mm.
A flood warning for western Manitoba, including the Parkland region, remains in effect. The Hydrologic Forecast Centre has also issued an overland flood watch for parts of western, central and southeastern Manitoba, excluding areas already in a flood warning.
Overland flooding occurs when high-intensity rainfall over a short period generates surface runoff that exceeds the capacity of ditches, drains and natural waterways, causing water to flow across the land and flood normally dry areas.
Residents in the affected areas are advised to monitor weather conditions closely and be prepared for rapidly changing conditions, localized flooding, road washouts and water accumulation in low-lying areas.
The Manitoba Emergency Management Organization continues to work with all local authorities and emergency management partners to provide guidance and support for response and recovery activities.
Several communities throughout the province continue to be impacted by high water levels. Reported impacts to date include loss of road access, flooded properties and damage to infrastructure. Manitobans are urged to watch for road closures and obey all detours. Do not travel on closed roads.
