Black ice could be the next danger for Saskatchewan motorists, as a rapid rise in temperature is forecast for the province.
According to experts from the Ministry of Highways, a quick change in temperature leads to frost.
Highways are susceptible because, as warmer air passes over colder pavement, the humidity in the air condenses on the road surface. The pavement has been so cold for so long, the moisture quickly freezes.
It has the potential of creating icy patches that are difficult to see. The condition is also known as 'black ice,' as the surface appears to be normal pavement.
Combine that with drivers lulled into a sense of security because of the warmer air, and Saskatchewan's highways may become just as dangerous as in a snowstorm.
The situation will not be helped with the addition of strong winds, also in the forecast.
Gusts between 50 and 70 kilometres in the southern part of the province are expected Tuesday, Doug Wakabayashi, a spokesman for the Highways ministry, said.
"It will serve to polish that pavement frost ... making it very slippery," he said. "And also all that loose snow that is around will start drifting as well."
The concern for black ice is expected to start later on Monday night and last well into Tuesday.
According to a safe driving guide from Transport Canada, snow and ice are more slippery at 0 C than at - 20 C or colder.
Wakabayashi said highway crews have access to more than 300 pieces of equipment, from graders to sanders, to help keep roads clear.
Motorists were being advised to check road conditions before heading out, and allow extra time to reach destinations.
