A massive weather system that threw a blanket of dust over Sydney is set to generate more unusual conditions across NSW.
The Bureau of Meteorology on Friday issued a severe weather warning for damaging winds over the state's southeast - stretching from the Victorian border up to the Hunter region.
Gusts of more than 90km/h are expected, and possible blizzards in the Alpine areas.
Sydney Airport has been restricted to using only one runway, which is already impacting travellers leaving and arriving in the city.
"International and Domestic terminals are experiencing some flight delays. Please contact your airline for more information," the airport tweeted on Friday morning.
Qantas is warning passengers of delays, as is Virgin Australia.
"Sydney and Melbourne Airports have reduced the number of flights allowed to arrive and depart each hour, which is impacting all airlines," Virgin said in a statement.
"This may also affect flights arriving and departing into other destinations across the network."
