A major low pressure system in southern Manitoba has spread heavy rain into central and northern Manitoba. On the northern edge of the precipitation, arctic air drawn into the system is yielding a band of nearly stationary, unrelenting, snowfall. The cities of Thompson and Flin Flon are currently seeing a rain/snow mix which will change back to snow this evening as colder air wraps in behind the very slowly departing low.

Final accumulations will be highly variable due to melting. Current indications are that 25 to 50 cm is likely to fall by Thursday night. The cities of Flin Flon and Thompson will see lesser amounts due to warmer temperatures and the rain/snow mix currently occurring.

Strong northeasterly wind gusts to 80 km/h persisting through Thursday will accompany this system.

At the eastern edge of the province, heavy rain is in the forecast.

Rainfall warning in effect for:

  • Shamattawa

Rain, at times heavy, continues.

The rain will continue on Thursday, but further accumulations are not expected to be significant.
