Extreme cold and Arctic air continue to blanket Saskatchewan, prompting Environment Canada to issue more extreme cold warnings across the eastern half of the province and most of the north.
By 4:10 a.m. Wednesday, the weather agency had issued its warning for Regina, saying very cold wind is expected for the day.
“Light northerly winds are combining with the extremely cold temperatures to produce dangerous wind chill values in the -40 C to -45 range. Wind chill values are expected to moderate this afternoon into this evening,” the warning said.
Regina was at -32 C by 7:30 a.m., with a wind chill value of -41 C; wind chill values throughout the day were forecast to be in the -30s C.
While the weather service did not issue a warning for Saskatoon, temperatures were still cold: By 7:30 a.m., the city was at -27 C with a wind chill value of -36 C.
Environment Canada also issued warnings for a number of other communities, including Prince Albert, La Ronge, Hudson Bay, Melfort, Yorkton and Estevan.
Reports came in to the 980 CJME and 650 CKOM text lines of temperatures at the Prince Albert airport hitting -39 C at 5 a.m.
Environment Canada advised people in areas under cold weather warnings to watch for symptoms of exposure including shortness of breath, chest pain, muscle pain and weakness, numbness and colour change in fingers and toes.
The weather service noted frostbite can develop quickly in extreme cold temperatures, especially where wind chill is a significant factor.
Exposed skin can freeze in 10 to 30 minutes with wind chill in the -28 C to -39 C range. That time drops to five to 10 minutes when the wind chill is in the -40 C to -47 range.
