The Ministry of Natural Resources and Forestry – Sault Ste. Marie District is advising area residents that a Watershed Conditions Statement – Flood Outlook is in effect in the District.
Residents in the Sault Ste. Marie District should keep a close watch on water conditions, regularly check for updated weather forecasts and stay away from fast-moving rivers and streams.
MNRF is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.
Locally heavy showers will continue today with isolated thunderstorms also expected this afternoon into this evening. Local rainfall amounts up to 25 mm are expected by the time the showers come to an end early Thursday morning. In addition, very mild temperatures will result in rapid snow melt and significant run-off during this time period.
After Thursday evening nighttime temperatures will drop back down to sub-zero temperatures and prevail into next week. Above zero daytime temperatures will continue with a high of 7 degrees expected for Saturday.
The latest local snow survey shows a continuing snowpack representing approximately 85 mm of water equivalent. This water equivalency is below the annual average for this time of year.
Water levels and stream flows across the region are moderately elevated from ongoing spring snow melt and current precipitation events.
Warm temperatures and precipitation are likely to further degrade the snowpack and ice on local waterbodies producing further runoff and increasing levels and flows.
Risks may include significant degradation of ice and possible ice jams from increasing temperatures and flows, and fast moving cold water with rapidly changing conditions. In
addition to unsafe ice conditions on area waterbodies there may also be localized flooding in areas with poor drainage.
A close watch on local forecasts and conditions is recommended.
This message will be in effect until (or updated before): Tuesday, March 30 2021, 12:00 AM
