THIRD SPRING FLOOD OUTLOOK RELEASED FOR MANITOBA– – –
Additional Snow, Delayed Spring Run-off Increases Flood Risk on Assiniboine, Souris Rivers
Manitoba Infrastructure and Transportation’s Hydrologic Forecast Centre of has issued its third 2013 spring flood outlook, which reports:
The delayed melt has left major rivers and tributaries with a thick ice cover and below-normal flows for the month of April. Future weather conditions will affect the magnitude of the spring flood potential. The amount of additional snow and rain, the timing and rate of the spring thaw and the timing of peak flows in Manitoba, the U.S. and other provinces will have a significant effect on flood potential. Delayed melt and the potential for spring rainstorms could result in rapid snow melt, aggravating overland flooding and increasing tributary flows. Based on today’s Environment Canada long-range weather forecast, melt and subsequent run-off may start as early as April 17.
Flood-fighting equipment has been placed around the province to bolster emergency response. This includes two million sandbags, six sandbagging machines, 17,000 super sandbags, 43 kilometres of Hesco cage barriers, 50 km of water-filled barriers, and 34 mobile pumps ready to deploy on an emergency basis provincewide.
This is the final outlook with daily flood reports to be issued beginning in April during the time of active melt and river flow. The detailed outlook with text and charts is available at www.gov.mb.ca/mit/floodinfo/index.html.
