A second winter storm in as many days began Saturday afternoon with about 15 centimetres of snow and ice pellets expected by Sunday night, according to CBC Ottawa climatologist Ian Black.

On Friday, about 15 cm of snow came down causing messy road conditions through the overnight and into Saturday morning.

The roads became even more slick due to some ice pellets falling Saturday afternoon. That caused traffic slowdowns and delays at the MacDonald-Cartier International Airport.

Road conditions continue to be slippery on Highway 401 east of Prescott and 417 east of Ottawa and Highway 34.

The City of Ottawa’s overnight parking restriction remained in effect, which means drivers can’t park on streets between 1 a.m. and 7 a.m. unless they have a street parking permit.

'A tale of two storms'

Environment Canada called for a “tale of two storms” late Saturday when a still-unpredictable winter storm is set to move into the Ottawa area from the United States.

A special weather statement said significant snow and ice pellet amounts are possible for the Ottawa Valley, with an ice storm possible across much of southern Ontario.

“There is still uncertainty surrounding the exact position of the storm track. Any change in the storm centre's track will affect precipitation amounts and type,” Environment Canada said in their statement.

“However, it is very likely that holiday travel will be significantly impacted.”
