Ottawa’s marathon 25-hour-long fog Wednesday was its longest lasting fog in 35 years.
The fog broke at least three records but fell short of the February 1981 record, when the city was obscured by a fog that lasted 30 consecutive hours.
The all-time record for fog was 36 hours in 1961.
@DevynBarrieNews Ottawa had consecutive 30 hours of fog during Feb, 1981. The all-time record was 36 hours during Nov, 1960.

The fog began Tuesday night and was dense enough to affect flights at the Ottawa Airport.
Environment Canada lifted its fog advisory Wednesday night.

Shouldn't the fog have burned off by now? pic.twitter.com/8csMxgY72F
