Environment Canada issued a special weather statement for most of Alberta Monday afternoon, warning “an abrupt change in the weather is coming.”

The weather agency said the change in weather is expected to begin Tuesday evening and peak by midday Wednesday bringing rain and significant wind throughout much of the province.

By Tuesday afternoon, the weather agency upgraded its advisory to include a wind warning for much of central, east central and southeast Alberta as gusts of 100 km/h will be possible Wednesday.

“A strong low pressure system is forecast to develop by Tuesday evening west of Edmonton near the BC border,” the statement reads. “This low will then move east-southeast through the province. As it does so, a big change in the weather is expected to occur.”

Environment Canada said rain is forecast for west-central Alberta Tuesday night and then for Edmonton and the Capital Region by Wednesday morning. By evening, the rain is expected to have moved across the border and into Saskatchewan.
