A powerful low-pressure system that crossed the border on Monday will be held back by strikes on the western prairies for another day before leaving. Rain warnings are still in effect for much of southern Alberta and central Saskatchewan.
The system carries huge amounts of rainfall, and locally 100+ mm is not excluded for some of the most difficult areas to the end. The largest amounts of precipitation will be directed to the southern foothills of Alberta.
The additional total rainfall that is yet to come is excessive for many areas. The northern foothills of Alberta and northern Saskatchewan could still see another 30-60 mm, with Calgary and Edmonton on the hook for another 15-30 mm.
In addition, widespread, strong northwest winds will continue until Wednesday, with gusts of 70-80 + km / h for Alberta and Saskatchewan. Some localized pockets of 90+ km / h are possible.

There is also a risk of lightning thunderstorms in the region on Wednesday.
All that will form will remain under strict criteria, but conditions may be favorable for the development of funnel clouds with some of the storms in eastern Saskatchewan.

Calgary is expected to receive 100 mm of rain with this system, and Edmonton can see up to 50 mm. Weather forecasters recommend that you be alert to the risk of flooding in some areas.
“For more information on the potential effects of floods on your community, please contact your municipality and the province of Alberta (rivers.alberta.ca) for the latest information and recommendations,” the Environment Canada and Climate Change (ECCC) said in a warning. for rainfall issued for Calgary. “Heavy rainfall can cause sudden floods and water build-up on roads. Localized floods are possible in low-lying areas. Beware of possible leaching near rivers, streams and gutters.”

Floods are likely, but the endangered infrastructure will be smaller streams, tributaries and agricultural fields, as well as localized streets. The likelihood of rivers overflowing and becoming widespread is generally low due to current levels, so no major damage is expected.
However, the city of Calgary has declared a local state of emergency as a precautionary measure.
According to local media, Mayor Joti Gondek says this will help emergency services if the need for evacuation comes true, but she does not anticipate that it is needed at the moment. Any potential evacuation will depend on the weather over the next few days.
