Parts of the coast, ranges and slopes of New South Wales and Queensland have gained some decent rain in the past few days and most places have a chance of more in the next few.
Some spots near the coastal border have seen more than a month’s worth in one or two days.
It is also its biggest rain in 10 months and biggest for September in more than 25 years.
Both Cape Byron (68mm) and Yamba (65mm) have also gained more than a month’s worth of rain in under two days.
Falls of 10-30mm have scattered as far south as Sydney and 10-20mm as far inland as the Guyra, Murrurundi and Katoomba.
The rainfall has been patchy in nature, typical of showers and storms.
Lismore, less than 30km from Ballina, has only gained six millimetres in the same time.
This system will weaken over the next few days, causing showers and storms to ease and become even more patchy.
However, later in the week another low pressure trough will move in from the west, bringing showers and storms to a similar region.
