Windy morning forecast for coastal NSW

Another blustery morning is predicted across much of coastal NSW as damaging winds, forecast to gust at up to 90km/h, developed overnight Monday prompting authorities to issue a severe weather warning.

Much of the heavy rain which saturated parts of NSW and Queensland has moved on, after dumping more than 100mm of rain in parts of northern NSW.

Almost 40mm fell on some of the worst-affected areas in Sydney.

The winds are predicted through much of the state's east and may affect people around Armidale, Newcastle, Maitland, Nowra, Bowral and Katoomba, the weather bureau has warned.

Conditions are expected to ease as the low-pressure system responsible for the nasty weather moves from NSW on Tuesday afternoon.
