Bouts of freezing rain in Queens and Kings County are expected to end early Saturday evening, but temperatures are falling fast, warns Environment Canada.

The national weather service issued flash freeze and freezing rain warnings for Prince Edward Island and most of Atlantic Canada early Saturday morning.

Temperatures stayed quite mild across most of P.E.I. on Saturday, hovering above 10 degrees across the Island, according to figures from Environment Canada. St. Peters even reached a high of 18 degrees.

The rainfall warnings ended by late afternoon, but the flash freeze warning is still in effect for Queens and Kings County.

Prince County is still under a freezing rain warning.

Environment Canada expects temperatures to drop "dramatically" on P.E.I. as a cold front moves into the province, resulting in "water freezing quickly, especially on untreated surfaces.

"Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous. Be prepared to adjust your driving with changing road conditions."

The national weather service said power outages may occur and that heavy downpours can cause flash floods and water pooling on roads.

Flash freeze warnings are issued when a rapid drop in temperature is expected, that can cause water from rain or melted snow on streets and sidewalks to quickly freeze.
