Widespread rain has affected the southeast of Australia, bringing the highest February rain since 1919 to some places.

Tropical Cyclone Dianne and the monsoon have indirectly affected the southeast by sending a large amount of moisture into a trough. This trough stretched from WA right through to Victoria.

Adelaide picked up its highest daily total in 8 years, with 32 to 9am on Saturday. Neptune Island in the West Agricultural picked up 48mm, their highest in at least 53 years for February.

Unlike recent Victorian rain events, the South West also received heavy rain. Hamilton recorded 26mm to 9am, which is more than the average monthly total rainfall.

Wilsons Promontory had its heaviest February rain since 1919, with 61mm in the gauge. The Northeast and Alpine Areas also had another bucket full, with 53mm to 9am at Falls Creek. This brings their monthly total to 418mm, the highest in about 20 years.

The trough also brought strong winds to Alpine areas with gusts up to 139km/h at Mt Hotham this morning. Thredbo had gusts to 130km/h and this is their strongest in three years.

The heaviest rain has now moved into southeast NSW.
