radar imagery from mornington island depicted a well-defined low-level circulation with defined banding features wrapping into the centre. situated in a very moist air mass and over the warm waters of the gulf, some intensification was expected before oswald struck the cape york peninsula. approximately 12 hours after being named, the storm made its second landfall north of kowanyama with winds of 65 km/h (40 mph) and the final advisory was issued by the tcwc in brisbane. although over land, the system was able to maintain a defined circulation and gradually reorganised as it moved southwestward. by 23 january, deep convection redeveloped over the circulation and a strong monsoonal flow became established to its north. a high pressure system over new zealand blocked the low pressure system from moving east, away from the queensland coast, allowing the low to move slowly along the queensland coast also causing it to stall near rockhampton and in southern queensland; feeding moist air from the coral sea into the low which resulted in a large area of convective activity with associated heavy rainfall and a low pressure trough over new south wales allowed the low to move south into the tasman sea. favourable upper-level conditions and ample moisture allowed the system to maintain its identity despite remaining over land for a prolonged period of time. by 30 january, the system had travelled more than and its remnants passed south of sydney in new south wales, emerging into the tasman sea.
