Once again parts of southern Ontario are under a blanket of fog as the unseasonable holiday weather continues.

Environment Canada issued another fog advisory this morning (Dec. 28) for parts of southern Ontario including Hamilton, Toronto, Caledon (but not Brampton or Mississauga), Halton Hills, Milton, Niagara Falls and St. Catharines.

Near zero visibility in patchy fog continues this morning, the advisory reads.

Visibility is expected to improve through the morning, however, fog patches may persist into the afternoon.

Once again, drivers should take care as visibility may be “significantly and suddenly reduced to near zero.”

“Travel is expected to be hazardous due to reduced visibility in some locations,” the weather forecaster advises. “If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop.”

The fog advisories started on Christmas Eve and continued through the week. The fog has been clearing by the afternoon but returning the next day.

Yesterday (Dec. 27), Environment Canada noted Niagara Falls had disappeared under cloud and fog in the morning.
