Fog at Adelaide Airport prevents planes from landingSunday August 24, 2014 - 15:06 EST
Thick fog over Adelaide has caused headaches at the city's airport, with at least one plane caught in a holding pattern before being diverted.
The Jetstar flight from Brisbane was sent to Melbourne after circling fruitlessly while waiting for conditions to improve.
An airport spokesperson said a Singapore Airlines flight was also diverted to Victoria, while three Adelaide-bound flights that took off from Melbourne were turned back.
They included planes owned by Virgin Australia, Jetstar and Tiger Airways.
The spokesperson for the airport said the fog had cleared by mid-morning.
Most of the affected passengers had been flown to Adelaide by 12pm (ACST) and plane scheduling was "back on track".
Bureau of Meteorology senior forecaster Mark Anolak said the conditions were created after a small cold front moved over Adelaide yesterday, producing showers in the city and in the state's mid-north.
The moisture combined with clear skies overnight, which in turn created a bank of fog over the mid-north that moved south and crept over Adelaide late in the morning.
The conditions also created a dense sea fog that stretched south of the city.
