Flood Watch for Sault Ste. Marie and Goulais River Areas

Flood Watch

Monday, April 27, 2020 – 5:00 PM: The Ministry of Natural Resources and Forestry – Sault Ste. Marie District is advising area residents that a Flood Watch is in effect for the District.

Residents of the Sault Ste. Marie District should continue to keep a close watch on water conditions, regularly check for updated messages and stay away from fast-moving rivers and streams.

The ministry is closely monitoring the weather and developing watershed conditions. Further updates will be issued as appropriate.


Description of Weather System:

The weather outlook for Sault Ste. Marie over next several days is for daytime temperatures of up to 12°C and with night-time lows to remain above zero. Clouds will move in during the afternoon on Tuesday with a 70% chance of showers this evening and overnight. Tomorrow will be cloudy as daytime highs reach 11°C with rain (2-4 mm) moving into the region after midnight. Rain is also predicted for Wednesday and Thursday bringing an estimated volume of 35-45mm and 25-35 mm respectively with gusting easterly winds and temperatures near 8°C. The four-day total volume of rainfall predicted may exceed 60-85 mm.

Water levels and stream flows across much of northeastern Ontario are moderately elevated from ongoing spring snow melt and recent precipitation events.

Above freezing temperatures and precipitation will further degrade the remaining snowpack and produce continued runoff, thereby increasing water levels and flows.

Description of Current Conditions:

Although water levels are currently below critical thresholds for the Goulais River, any increases in the amount of precipitation forecasted and coupled with continued melting of the remaining snow pack could result in a subsequent rise in water levels.

Risks may include increasing flows, fast moving cold water with rapidly changing conditions.

A close watch on local forecasts and water conditions is recommended.



This message will be in effect until (or updated before): Friday, May 01 2020, 12:00 AM .
