Thunder Bay – Weather – Early Tuesday is starting off murky and hazardous across the Kenora–Lake of the Woods corridor. Environment Canada has issued a Yellow Advisory for Fog, warning of near-zero visibility in dense fog this morning.

To make matters worse, there may also be patchy freezing drizzle, which can leave a thin, nearly invisible glaze of ice on untreated roads and sidewalks.

If you’re commuting or travelling early, slow down, use your lights, and expect sudden visibility drops—especially near low-lying areas and lake-adjacent routes.

Weather Trivia

Fog forms when air near the ground becomes saturated—often around lakes and low-lying terrain. When temperatures hover near freezing, freezing drizzle can occur from low clouds containing supercooled droplets, creating a thin ice glaze that’s often more dangerous than heavier snowfall because it’s hard to see.
