The Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) –
Sault Ste. Marie District is advising area residents that a Watershed Conditions Statement –
Flood Outlook is in effect for the District.

Residents in the Sault Ste. Marie District area should keep a close watch on water and ice
conditions, regularly check for updated weather forecasts, and stay away from fast-moving
rivers and streams.

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

TECHNICAL INFORMATION
Description of Weather System
Daytime high temperatures today and Saturday will remain just above zero with trace
amounts of mixed precipitation and nighttime temperatures from -5 to -10 degrees Celsius
(oC). The current colder weather will give way to a warming trend starting Sunday which will
see daytime highs reaching from between 5 to 9 oC and with nighttime highs remaining
above zero degrees through to the end of next week. These forecasted milder temperatures
will likely result in rapid snow melt and significant run-off during this time period.

The latest local snow survey shows a continuing snowpack representing approximately 224
mm of water equivalent. This water equivalency is above the annual average for this time of
year.

Description of Current Conditions
Water levels and stream flows across the region are moderately elevated from ongoing
spring snow melt and recent precipitation events.
Forecasted warm temperatures and precipitation will begin to accelerate the melting of the
snowpack and ice cover on local waterbodies producing additional runoff and increasing
levels and flows.

Risks may include significant degradation of ice, possible ice jams, 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.
