Rainfall totals from the current spell of wet weather could more than double over the next few days as a low pressure trough lingers over parts of northeast New South Wales, with shifting across the border into Queensland from this afternoon. Parts of the Northern Rivers have picked up over 200mm over the last 48 hours, with Evans Head collecting 257mm, Yamba 224mm and Ballina Airport 213mm as of 09:00 am this morning. All three of these stations and surrounds have the potential to receive an additional 150-200mm by the end of the working week, with most of this likely to fall through Tuesday. As the trough shifts further north through today, rain gauges in southeast Queensland will begin to get a workout, with 150-200mm also possible here. Coastal adjacent areas look to receive the heaviest of the falls. This means there is a good chance some places will exceed their average June rainfall. The system responsible will clear southwards of the worst affected region by Friday, as a high pressure ridge builds from the west and dries out conditions in time for the weekend.
