Flooding rain soaks eastern states

Ben Domensino, 26 February 2018

The heaviest rain in more than a year inundated parts of Queensland, NSW and the ACT during the last 24 hours.

An upper-level low pressure system over southeastern Australia interacting with a large mass of warm, moisture-laden air to its east caused widespread rain and thunderstorms on Sunday and Monday morning.

Widespread falls of 50-80mm were recorded between Newcastle and Canberra during the 24 hours to 9am on Monday.

Williamtown (54mm), Singleton (41mm), Canberra (64mm), Gosford (85mm) and the Sydney suburbs of Canterbury (70mm) and Terrey Hills (83mm) all registered their highest daily rainfall total since 2016.

The heavy falls produced flash flooding around Canberra on Sunday, with close to 50mm falling at Canberra Airport between 8am and 11am.

Further north, a rain gauge near Inverell received 112mm during the 24 hours to 9am Monday, while Glen Innes saw 64mm at the airport, its heaviest fall in 11 months.

Across the border Charleville picked up 31mm, which was its heaviest daily total in just over a year. Almost half of this fell in 10 minutes during a storm on Sunday afternoon.

A low pressure trough will continue to generate showers and thunderstorms in eastern Australia today, before the wet weather contracts into central and northern Queensland from Tuesday.
