Fog, freezing drizzle advisories for Calgary end

Fog blanketed Calgary and much of southern Alberta once again Thursday, leading to poor visibility and slippery roads.

A fog advisory was initially issued Tuesday night by Environment and Climate Change Canada (ECCC) and was in place until just before 11 a.m. Thursday.

Accompanying the fog was a freezing drizzle advisory, which was also ended just before 11 a.m.

The agency previously said the fog was expected to lift near noon, but may redevelop again Thursday night.

According to the ECCC, fog advisories are issued when near zero visibilities in fog are expected or happening.

Travel was expected to be hazardous due to reduce visibility in some areas and freezing drizzle had the possibility to make surfaces like highways, roads, walkways, and parking lots icy and slippery.

According to the ECCC, freezing drizzle can produce thin, hard-to-detect layers of ice.

Freezing drizzle advisories are issued when drizzle falling in sub-zero temperatures is expected to freeze on contact, and over time create icy surfaces.

ECCC previously said the drizzle was expected to taper off near noon Thursday.

If visibility is reduced while driving, motorists are advised to slow down, watch for tail lights, and be prepared to stop.
