Environment Canada says the Guelph area and Waterloo Region are in for a windy afternoon and evening on Monday.
The agency has issued a special weather statement that calls for strong winds gusting up to 80 km/h. It is also warning of poor visibility due to blowing snow.
Along with Guelph and Waterloo Region, the advisory also covers Wellington County.
The strong winds may throw loose objects, cause tree branches to break and damage property, Environment Canada said.
It added that power outages are also possible.
The winds should pick up in the afternoon before diminishing in the evening.
