⚠Weather Update: hazardous coastal conditions, developing heavy rainfall, flooding risk for Qld


Hello from the Bureau, with an update on the hazardous coastal conditions and developing heavy rainfall and flooding risk for Queensland this long weekend. Heavy rainfall eased on the north tropical coast yesterday, as the remnants of ex-tropical cyclone Nora continue to weaken. River levels are generally falling for now; however, Flood Warnings do remaining in place for multiple catchments. Our attention now turns to ex-tropical cyclone Iris and the severe weather which it is expected to bring to Queensland this weekend and into next week. This strong pressure gradient on the south side of the low is currently generating strong winds and an easterly swell over the subtropical coast, and that includes
the Byron Coast of New South Wales. If you’re thinking of heading to the beach or out on the water this long weekend, please be aware that surf and swell conditions could be hazardous for coastal activities including rock fishing boating and swimming. Ex-tropical cyclone Iris should then move north-west during Friday and Saturday, with a slight risk of development into a tropical cyclone but very little significant rainfall expected on these days. However, during Sunday and Monday there is growing uncertainty in the movement and intensity of the system, and increasing potential for heavy rain. The north tropical coast could experience another period of heavy rainfall from late Sunday or Monday into mid next week, and these catchments are very saturated and won’t require much additional rainfall for flash flooding and renewed river rises. However, if the low stays just a little bit further offshore, then the far north could remain mostly clear; and if that low just drifts a little bit further south, then that bulk of the rain could fall over the Central Coast instead. With this uncertainty, and a lot of travel expected in this busy holiday period, we’ve issued a Flood Watch for coastal catchments from Cairns to just
north of Burnett Heads: It’s an early heads-up to keep an eye on forecasts and warnings for your area as the long weekend unfolds.
