Environment Canada’s rainfall warning is expected to be in effect through to Thursday morning with anticipated rainfall amounts ranging from 50 to 75 mm with a few areas possibly reaching 100 mm.  So far, our watersheds have received up to 50 mm but this is highly variable with some areas only receiving 10-15 mm.  Our watersheds have done an excellent job absorbing most of this rainfall, but they are now saturated, and runoff is anticipated from the added moisture. Stream and river flows are expected to rise throughout the day but are not expected to cause unusual flooding. Flooding may occur in low lying areas that typically flood seasonally.

Recent warm temperatures have significantly lowered the snow pack throughout our watersheds.  In most areas, the field snow has been completely exhausted with snow restricted to woodlots and fence rows.  The melt has saturated the soils but has not caused any significant runoff to our streams and rivers.  River flows are normal for this time of year.
