Saskatchewan flooding

Above: Weyburn, below Yellow Grass.
A very slow moving low pressure area spinning over the prairies has produced more severe flooding in southern Saskatchewan. Since Friday over 100mm of rain has fallen in Weyburn in the southeast portion of the province. Yellow Grass and Radville to the northwest are reporting major flooding as well with portions of Highway 39 under water. A state of emergency is in effect in Weyburn where several homes and trailers have had to be evacuated and a boil water advisory is in effect. More rain is expected today, washing out roads and flooding basements already. I know the area very well and it is normally very sunny and very dry at this time of year. As a matter of fact Yellow Grass holds the national record for heat at 45C (113F), recorded on July 5, 1937. I lived in the region between 1997 and 2000, and while heavy rain does occur, it is rare to this extent. In addition to the heavy rain in the east, over 150mm of rain fell in Assiniboia, including 91mm on Friday alone in heavy thunderstorms that produced a wind gusts to 91km/h.Montreal: Despite the good weather, it was not a good weekend on Quebec roads. Numerous accidents produced a dozen fatalities, one of which I sadly witnessed on Highway 20 near Coteau du Lac while I was heading to Ontario. The weather this week will be decent to start with sunny skies and warm temperatures. By Thursday a slow moving frontal system will bring showers and thunderstorms that will last into the weekend.
