Environment Canada issued a fog advisory covering much of Alberta on Tuesday, warning visibility may be significantly and suddenly reduced to near zero.
The advisory, issued just before 5 a.m., warned widespread fog had developed across central Alberta.
“Along with the fog, areas of drizzle have developed – and in some regions, where temperatures have dropped below zero, freezing drizzle is occurring,” the advisory said. “Travel will be affected due to the near-zero visibilities and slippery road conditions.”
“Travel is expected to be hazardous due to reduced visibility.”
The widespread fog and drizzle continued through most of central Alberta until late Tuesday morning – and into the early afternoon for regions in east-central Alberta.
Fog advisories are issued when near-zero visibilities in fog are expected or occurring.
