Rain will continue overnight on P.E.I. ahead of a messy weather day Saturday, with rainfall warnings and freezing rain warnings in effect for all three counties.

"More wet weather is ahead with periods of rain tonight and even heavier rain on the way for Saturday," said CBC Prince Edward Island meteorologist Jay Scotland.

"P.E.I. should expect an additional 20 to 40 mm of rain this evening through Saturday night," he said.

With snow covering drains and the ground frozen, there could be nowhere for the rain to go in many parts of the Island.

"My main concerns with the rain is for localized flooding — basements and low-lying areas — and water pooling on roads," said Scotland.

The temperature will fall overnight, he said, with a risk for significant freezing rain starting in the early hours in Prince County, then spreading across the Island through the day.

That freezing rain could result in icy roads, walkways and steps, said Scotland.

The chance of significant snowfall is over for most of the Island, he said, but western Prince County could see an additional 5 to 10 cm of snow and ice pellets Saturday afternoon and evening.

By Sunday, any additional precipitation will be fairly light, said Scotland, and temperatures will stay around the freezing mark.

On Friday, public schools and Holland College cancelled classes for the day, given that the worst of the weather was expected midday. Most offices and businesses stayed open.

Snow began falling in Prince County at 6 a.m. AT and had spread across the province by 9 a.m. The change to rain began in the west and had reached Charlottetown by late morning.
