In what has become a regular occurrence in southeast Saskatchewan as of late, Environment Canada has issued a severe thunderstorm watch for the region.
Both the Estevan and Carlyle jurisdictions issued advisories at 3:54 p.m.
It says conditions are favourable for the development of dangerous thunderstorms that may be capable of producing strong wind gusts, damaging hail and torrential rain.
In a further development Monday night, Environment Canada said a big, severe weather system has formed over Montana and North Dakota. A few thunderstorms are forming ahead of this system over southern Saskatchewan.
They could be conducive of up to golf ball sized hail and up to 125 millimetres of rain.
There are thunderstorms in the forecast for the southeast for Monday and Tuesday.
The Mercury will have more details as they become available.
