FLIGHTS out of Sydney Airport have been delayed as storms pummel the city.
The news comes as storms spread rapidly across NSW bringing heavy rain and fears of flash flooding.
The Bureau of Meteorology issued a late, severe weather warning just before 4pm.
Sydney was hit by the storm about 4pm, just in time for the commute home, with many people caught out in the heavy rain.
"There is the possibility they will continue into the night, but with severe thunderstorms they can be hard to predict."
Despite being only halfway through March, most stations along the NSW coast and northern inland ranges have already recorded a month's worth of rain. The average number of rain days in March is 13.6 - that's already been tipped at 17.
Earlier today the BOM also issued a severe thunderstorm warning for Central NSW. Areas hit included Gosford, Orange, Goulburn, Dubbo, Wagga Wagga, Albury and Bourke.
It comes after a week of horror weather across the north coast, with flash flooding and the tragic death of 11-year-old Ryan Teasdale, who was sucked into a stormwater drain in Illawarra.
BOM spokesman David Barlow said rain was expected to continue until at least Friday, with the Northern Rivers area most affected.
In the past 24 hours, the Northern Rivers has seen the most rain with 112mm chucking down on the region.
Condobolin, west of the central west, has been hit with 58mm. Dubbo saw 49mm and Cooma, in the Southern Tablelands, was hit with 70mm of water.
Mr Barlow said Friday would be the wettest day of the week for the region.
