Saskatchewan has been blanketed with a fog advisory from Environment Canada.
Several areas, including the Battlefords, Saskatoon, Weyburn and Estevan, Moose jaw and Regina are all under the advisory.
Meteorologist Terri Lang said the warm air is mixing with cold air, which causes the fog to form.
“Because the fog droplets themselves are still liquid, they’re not frozen, mixed with the temperatures below zero and still having that liquid water around,” Lang said. “As soon as those water droplets run into something like trees, sidewalks, cars that are below freezing, they freeze onto it.”
Lang said road conditions will be treacherous.
“We’ve got a double whammy with really low visibility and this freezing fog freezing onto the roads and such, people really do have to take care,” Lang said. “Checking the highway hotline before they head out is very important.”
Lang also said snowy weather is on the way for southwest Saskatchewan as well.
“There’s a bit of a Colorado low to the south of the border and there’s kind of a little extension of that, and we’re expecting some fairly heavy snow to move over the southwest corner of the province through the day (Saturday), so fog will be gone, but then snow moving in to some of these areas,” Lang said. “Drivers really need to be on their toes if they’re travelling this weekend.”
However, Lang says the fog will clear by sometime Saturday.
