Thick fog has shrouded Canberra this morning, reducing visibility to 100 metres at 5am, thick enough to interrupt air and road travel.
The fog has formed with help from clear skies and light winds, which has allowed moisture from recent rain to condense into droplets.
It should start to burn off soon after sunrise, but may hang around as long as about 9am. Wind should start to get strong enough from 9am to mix up the warming air and disperse the fog.
This morning has been foggy in many places along the Great Dividing Range, from western Victoria to central Queensland.
Fog is again a risk in the national capital and elsewhere along the Great Dividing Range on Friday and Saturday mornings with help from mostly clear skies and light winds.
Cloud and wind should increase over the weekend as a low pressure system deepens off the New South Wales coast. This will reduce the chance of fog over the ACT and most of the ranges.
