Southern Ontario: Fall Weather Hazards Outlook for Friday, October 8, 2021

Forecast Discussion

Heavy fog has developed around the Hamilton/Niagara region this evening and is expected to further expand to encompass parts of Southwestern Ontario overnight and into Friday morning. Fog is also possible throughout Eastern Ontario during the early morning hours on Friday. This could cause reduced visibility on the roads and make for difficult travel conditions. The fog will dissipate after sunrise.
