Parts of the nations southeast have awoken to a thick blanket of fog this morning, dropping visibility to as low as 50 metres.
Persistent onshore winds have led to a moisture laden atmosphere. A large high pressure system allowed for light winds and mostly clear skies overnight. This allowed the temperature to cool enough for the fog to form.
The fog was thickest and most widespread across the Australian Capital Territory, New South Wales and Victoria whilst patches also developed in Tasmania.
In the Snowy Mountains, the visibility in Cooma dropped to 100 metres in the small hours of the morning and was still only at 200 metres at 7am. Further north in the Hunter, Murrundi Gap had visibility drop to 100 metres where it remained at 9am on Sunday. In Sydney, the western suburbs saw the thickest fog with suburbs such as Richmond dropping to 100 metres just before sunrise. Canberra was also enveloped in fog that dropped visibility as low as 200 metres. This coupled with a cool start to Sunday morning with a low of five degrees, making a sleep in a little more enticing.
Across the border in Victoria, Portland in the South West, dropped to just 50 metres. On the other side of the state in Sale, visibility was as low as 100 metres.
Over Bass Strait, those in Launceston in northern Tasmania also awoke to thick fog. Visibility remained as low as 150 metres just after sunrise.
For most of these centres the fog has burned off fairly quickly thanks to mostly clear skies allowing the sun to warm the surface.
