Heavy rain, hail and damaging winds have lashed parts of central west NSW, with the drenching set to continue overnight for much of the state.
Sydney was spared much of the wild weather on Monday evening but is due to gets its share on Tuesday with a severe thunderstorm warning in place for large hailstones and damaging winds.
The State Emergency Service says it received 150 calls for help across NSW as a low-pressure system made its way towards Queensland, bringing hailstones the size of golf-balls in some areas.
Dubbo bore the brunt of the storm, recording 69mm of rain by 8pm on Monday.
Emergency crews responded to 65 calls for help in the area, SES spokesman Phil Campbell said.
“The main damage in Dubbo was the Charles Sturt University campus which had to be evacuated because of water damage,” Mr Campbell told AAP, adding there were reports of aged care and childcare facilities being shut down.
A severe thunderstorm warning, which could bring flash flooding, damaging winds and large hailstones, remains for much of the state.
Areas which may be affected include Armidale, Orange, Mudgee, Bathurst, Tamworth, Gunnedah, Moree, Narrabri, Dubbo, Parkes, Wellington and Coonamble, according to the Bureau of Meteorology.
The storm cell is expected to bring up to 50mm of rain to Sydney on Tuesday.
“While there is a risk of a super cell thunderstorm, that decreases overnight,” bureau forecaster Rebecca Kamitakahara told AAP.
“They are still predicted to bring destructive winds however,” Ms Kamitakahara said, adding that the central and north-west slops and plains are most at risk.
The SES said it was preparing for a busy week ahead with severe thunderstorms forecast to hit the northeast parts of the state from Wednesday to Friday.
“We’re asking residents to be prepared, especially things like clearing gutters and drain pipes because they led to a lot of water damage to some of those homes in Dubbo,” Mr Campbell said.
