WEDNESDAY: HEAVY RAIN STARTS TO REDUCE, LOCALIZED FLOOD IS STILL A THREAT
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 heaviest rainfall streams by Wednesday will be directed to the Alberta, Saskatchewan border, with only delayed rainfall forecast in southern Alberta, where 60-70mm of rain has been reported locally so far. Forecast for an additional 15-30 mm of rain for settlements along the borders of the province.
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 were numerous reports of trees being felled Tuesday in parts of Alberta.

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. Funnel clouds were reported in parts of southeastern Alberta on Tuesday.
There is still some uncertainty as to where the highest total precipitation will be, and some built-in thunderstorms in the system will also lead to additional amounts of precipitation.
As a result, residents must not give up vigilance when it comes to the threat of floods.
“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 accumulation on the roads. Localized floods are possible in low-lying areas. Beware of possible leaching near rivers, streams and gutters.”

The city of Calgary declared a local state of emergency as a precautionary measure Monday afternoon.
According to local media, Mayor Joti Gondek said this would help emergency services if an evacuation was needed, but she did not anticipate that it would be necessary at the moment.

The system will send temperatures to fall well below the seasonal ones for mid-June. After a seasonal weekend, the daily highs in Calgary will fall in the middle of the teens by the middle of the week.
The active model continues over long distances, especially in Alberta. A few more rounds of widespread rain and thunderstorms are likely to begin this weekend and continue until the middle of next week. This will be very useful for replenishment of groundwater and potential erasure of land in much of the region, but also the risk of flooding.
