A very wet weekend for southeast Qld, northeast NSW
11:48 AEST A prolonged rainfall event is set to bring large totals to parts of NSW and Qld from Saturday, with possible heavy falls and flooding. A low-pressure system in the Coral Sea, a deepening coastal trough and persistent easterlies will bring moisture-laden air into southeast Qld and northeast NSW will bring days of rainfall to the region. While there is not a drop of rain on the radar over southeast Qld and Northeast NSW on Friday morning, the mass of cloud associated with a low in the Coral Sea will enhance rainfall over the weekend.
- 10:07 AEST Southerly surges across the southeast
- 13:20 AEST Generation gone with the wind
- 11:29 AEST Devilishly dry in Tasmania
- 16:41 AEST Dubai deluge: a year's rainfall in a day
