Yet another rainfall warning has been issued for the region as a storm system draws near.

Environment Canada says between 20 - 40 mm of rain could fall between Thursday evening (May 19) and Friday overnight (May 20).

Temperatures are expected to drop into the low single digits on Friday. As a result, the rain may become mixed with wet snow at times. However, most of the snow should melt on contact and no snowfall accumulations are anticipated.

The additional rain will only worsen the near historic water levels and flooding that has impacted the region in recent weeks.

Since May 1, a total of 107.6 mm of rain has fallen in Kenora this month which is well above the average for May of 80.8 mm.
