Dynamical models suggest a continuation of cooling in the NINO3.4 region for the next few months with conditions near or meeting La Niña thresholds expected from October to January or February 2021, before a warming and return to neutral conditions by March. These conditions should result in a near average number of Tropical Cyclones (TC) over the Australian Region, with about 8 expected and with 4 becoming Severe Tropical Cyclones (STC). Accumulated Cyclone Energy (ACE) is expected to near the climatological average across the Northwest region and below average over the remaining regions. About 5-6 coastal impacts are expected across all regions.
