The freezing rain warning extends from Sault Ste. Marie east to North Bay and Mattawa.
“Freezing rain may change over to rain late this afternoon or evening for locations near the North Channel and the city of North Bay as temperatures briefly rise above the freezing mark,” Environment Canada’s weather alert said Sunday morning.
“Precipitation will transition to ice pellets and then snow from west to east Monday morning. Easterly winds will become northerly on Monday morning with gusts up to 50 km/h. This may exacerbate the situation if there is ice build-up on tree limbs and power lines.”
Further north, in Timmins east to Temiskaming Shores, snowfall between 20 and 30 cm is expected.
“Snow may mix with or transition to ice pellets this afternoon through tonight, particularly for locations along and south of a line from Gogama to Kirkland Lake. A risk of freezing rain will also exist in these areas,” the weather alert said Sunday afternoon.
“For locations that receive ice pellets and freezing rain, snowfall amounts will be reduced. A sharp gradient in snowfall amounts may exist to the north and south of the axis of heaviest snow. All precipitation will transition to snow from west to east late tonight into Monday morning.”
