Areas in the Pilbara region in far northwest WA have had their heaviest dry season rainfalls in over a decade. A rogue trough bringing in upper level tropical moisture far further south than is usual, with strong gusty lower level warm winds created instability over the Pilbara. Paraburdoo airport collected 22.2mm over 24hrs to 9am, their highest recorded rainfall for September since the start of records in 1974 Newman Airport received 11mm over 24hrs to 9am, their best rain for September since 2006. This uncharacteristic rainfall outside the wet season is characteristic of the effects of La-Nina, trending towards wetter conditions in the northwest of Australia, and with a La-Nina season soon to be officially declared, be sure to keep track of the climate situation on weatherzone.com.au
