On March 4, 2026, Environment Canada issued a fog advisory for Tecumseh, Ontario, and the surrounding Windsor-Leamington-Essex County region. The alert was put in place to warn morning commuters that visibility could drop to near-zero, making travel on local roads dangerous.
The advisory was active from 5:01 AM until 10:15 AM on Wednesday morning. The alert was classified as yellow under the federal government’s weather alert system, representing a moderate threat to the area. According to weather data, visibility was significantly reduced throughout the morning commute.
Drivers were told to slow down and leave extra space between their vehicles and the cars in front of them. The official warning also advised motorists to use their lights and be prepared for visibility to change suddenly while driving.
Fog advisories are common in this part of the province during the spring months. The region often sees thick fog because of the influence of the Great Lakes and other nearby waterways.
