The Queensland tropics are enduring an onslaught of rain as Ex-Tropical Cyclone Oswald is downgraded.
Ex-Tropical Cyclone Oswald became a cyclone in the Gulf of Carpentaria yesterday afternoon before it came onshore this morning near Kowanyama and weakened to become a tropical low. Despite the system being downgraded, it is likely to produce vast amounts of rain to the Peninsula, having already brought over 150mm to Kowanyama.
The old saying 'when it rains, it pours' is certainly true on the North Tropical Coast at the moment. Parts of this district have had more than a foot of water in under 24 hours. A small town just south of Innisfail recorded a whopping 332mm while nearby South Johnstone gained 288mm since 9am yesterday. It receives falls above 250mm once a year on average. Widespread falls in excess of 100mm were recorded from Innisfail to Ingham.
The heavy falls on Queensland's east coast have been due to the monsoon trough and a small low just off the east coast. This low has funnelled strong and moist easterly winds onto the coast near Innisfail overnight and has barely moved, leading to very large totals.
Today, heavy rain will continue between Innisfail and Townsville, with heavy rain gradually moving further south in coming days. Meanwhile Ex-Tropical Cyclone Oswald will remain over the Peninsula, triggering heavy rain, particularly for western parts of the Peninsula including Kowanyama and Weipa, which have both already gained over 100mm.
Over coming days the heavy falls will continue across almost the entire Peninsula and stretching along the east Queensland coast as far south as Mackay. Some localities with experience three day totals of almost 700mm. Heavy falls from this system should linger in the state until at least the end of the week with heavy rain likely to progress further south on the weekend.
