Roads 'very poor' Saturday as first significant storm of season hits ...

Residents of Prince Edward Island experienced their first significant snowfall of the season Saturday.

The Island remained under a winter storm warning with blowing winds and up to 20 centimetres of snow possible by the evening, according to Environment Canada. That is down from an earlier forecast calling for up to 25 centimetres. 

Shortly before 3 p.m., RCMP reported roads on the Island to be "very poor" and said that several cars have gone off the road.

The storm caused the cancellation of all ferry crossings between Wood Islands, P.E.I., and Caribou, N.S., on Saturday.

The weather did not cause any cancellations at Charlottetown Airport, but the 1:17 p.m. Porter flight from Ottawa arrived about an hour late. Air Canada's 3:30 p.m. flight from Montreal was also delayed.

The Confederation Bridge was closed to high-sided vehicles for much of the day, but by 5 p.m. was reopened to all traffic.

UPEI's Charlottetown and St. Peter's Bay campuses were closed for the day.

The Atlantic Veterinary College teaching hospital remained open for emergencies.

Both the Simmons Sports Centre and Cody Banks Arena in Charlottetown were closed, as was Credit Union Place in Summerside.

Grocery stores and pharmacies remained open.

Overnight parking bans are in effect for both Charlottetown and Summerside.
