Mild temperatures across the Greater Toronto Area this weekend has caused ice and snow to thaw, creating a slushy mess.

Environment Canada is calling for 15 to 25 mm of rain as temperatures soar to a high of 8 C. Many residents awoke Saturday morning to a thick fog across much of the region, creating limited visibility for motorists.

Both Toronto Pearson and Billy Bishop Airport advised travellers to check their flight status ahead of time as the weather was causing some delays.

The Toronto Region Conservation Authority has sent a warning to GTA residents to be aware of "the combination of slippery and unstable banks, unsafe ice and extremely cold water temperature that will create very hazardous conditions close to any river, stream or other water bodies."

There's also the possibility for flooding on roads, underpasses and in low-lying areas, Toronto's head of transportation services said.

"The threat now is just with the melting snow and the imminent rain coming in over the weekend that we're going to have some localized ponding on the roadways," Peter Noehammer said.

Noehammer said so far the precipitation hasn't created any problems but had this advice for homeowners.

"For your own property, if there's any snow buildup around your window wells, your doorways and entrances into your home, try to avoid water that could come into your home by pushing that away," he said.

"Getting it away from the perimeter of your house so it can find its way to the driveway, to the roadway, and drain away."

Etobicoke resident Flora Sardina woke up at 2 a.m Saturday to the sound of water dripping into the basement of her home.

"We spent hours trying to get rid of it this morning and it's still coming down," she said after calling a plumber to help fix the leak.

One company told CBC News Sardina was not alone, and they had been kept busy all day dealing with flooded basements.
