But it was one week before that Tropical cyclone Owen weakened and was downgraded to a tropical low on December 4, 2018. The tropical low pressure area, also called 05P revived and became a little better organized before it hit the Queensland coast on Dec. 9. Winds in the cyclone had increased to about 35 knots (40 mph) as it moved ashore. The disturbance is expected to intensify again as it moves westward over the warm waters of the Gulf of Carpentaria. Lower vertical wind shear is also predicted to contribute to a more favorable environment for the low's intensification into a significant tropical cyclone.

The GPM core observatory satellite passed above Tropical Cyclone Owen's remnants as they approached Australia's coast on December 9, 2018 at 11:31 p.m. AEST (8:31 a.m. EST/1331 UTC). GPM's Microwave Imager (GMI) and GPM's Dual-Frequency Precipitation Radar (DPR) instruments collected data that showed the intensity of rainfall in the low's convective storms. GMI indicated that rain was falling at a rate of over 32.4 mm (1.3 inches) per hour over northeastern Queensland's coastline. GPM's DPR revealed that rain was falling at a rate of greater than 52 mm (2 inches) in feeder bands in the Coral Sea off Australia's coast.
