Dense fog created near-zero visibility for portions of central and southern Alberta Friday morning, prompting Environment and Climate Change Canada to issue fog warnings, including for the city of Calgary.

In their advisory, the ECCC explained: “Travel is expected to be hazardous due to reduced visibility in some locations.”

As of 7 a.m., foggy conditions could be seen on 511 cameras in Alberta, including Calgary, near Okotoks, Airdrie and west of Drumheller.

Winds will pick up throughout the morning, helping to mix up that fog, and Calgary will be under clear skies until early Friday evening.

Chinook conditions will develop for Sunday, with snow and rain on the BC side of the Rockies and producing warm westerly winds on the Alberta side, especially in the southern regions.

This will be short-lived as a frontal system is expected to move in late Sunday, dropping temperatures to 1C for Monday’s high.

Calgary will likely see some precipitation on Monday, although accumulations appear to be minimal at this time.
