Much of southern Manitoba is under a special weather statement as yet another Colorado low sets its sights on Manitoba.
Environment Canada put out the statement around 3:30 Wednesday afternoon. Meteorologists stress that the low pressure system is still difficult to forecast with certainty, but it's likely much of southern Manitoba will see precipitation, mostly in the form of rain over the weekend.
"We have yet another Colorado low, a large low-pressure system coming up from the states," says Natalie Hasell with Environment Canada. "The greatest impact will be seen south of the border. But we are expecting this system will also affect the Canadian prairies."
It will be the third major Colorado low to hit southern Manitoba in just as many weeks, and many areas are now battling overland flooding and swollen river banks.
"Uncertainties with this system remain higher than the previous two; there is a chance the system remains entirely in the United States, however, the largest likelihood is that areas near the international border will receive the largest amount of precipitation," the statement says.
Hasell says some models make it look like the system will miss Manitoba altogether while others show the lower part of the province could see a mixture of rain and potentially snow with the lows overnight on the weekend remaining around zero degrees Celsius.
"Current guidance suggests some areas may receive an additional 20 to 50 mm of precipitation, most of which will likely fall as rain, although some snow is possible over the higher terrain of southwestern Manitoba."
For Winnipeg, rain is expected to begin Friday evening and last until sometime Sunday.
