Heavy fog has caused headaches this morning, with some domestic flights from Brisbane Airport cancelled or facing delays of up to 90 minutes.
Residents woke up to a thick blanket of fog over Brisbane, causing visibilities issues across the city.
Two Virgin Australia flights flying in and out to Melbourne have been cancelled, and another two flights flying into Brisbane from Sydney and Newcastle were delayed by 90 minutes.
A spokeswoman at Tigerair said flights would be delayed by up to 45 minutes, but there was “no major effect” on operations.
There has been a flow-on effect with a number of domestic arrivals and departures delayed into the mid-morning period.
Senior forecaster Diana Eadie told ABC Radio Brisbane the fog had formed in the valleys and around the Ipswich area before it gradually moved toward the city overnight.
She said it was odd to see fog at this time of year.
“We typically see a lot of fogs around the winter time, possibly early spring, but to see one in the middle of October is certainly quite unusual,” she said.
“What you’re going to see over the next few hours is its gradually going to lift and become more like a thick deck of lower cloud.”
Ms Eadie said there was a chance of a shower on the forecast, and a possible thunderstorm developing inland.
Heavy showers are expected across the weekend.
