Freezing rain warning issued in Ottawa-Gatineau

A freezing rain warning throughout Ottawa-Gatineau could be upgraded to a winter storm warning due to significant snowfall by Monday, according to Environment Canada.

The freezing rain warning was issued at 5 a.m. Sunday.

A low-pressure system from Colorado is heading east and is expected to reach Eastern Ontario Sunday evening, with snowfall amounts of anywhere from five to 10 centimetres. It should change to freezing rain overnight and persist well into Monday, the weather agency warned.

In the Ottawa Valley, snowfall amounts might exceed 10 to 15 centimetres, which would breach snowfall warning criteria and call for an upgraded severe weather warning.

Snow in Ottawa is expected to begin falling Sunday evening, sometimes heavily. It's expected to change to ice pellets mixed with freezing rain overnight, with a low of -7 C and a total accumulation of five to 10 centimetres.

Periods of ice pellets mixed with freezing rain are expected for Monday. It'll change to freezing rain in the morning, and that rain will persist into the early evening, with a high of 1 C.

By Tuesday, the sun is predicted to return with a low of -10 C and a high of -6 C.
