Hello. It’s looking like another big week weather-wise this week, with ex-tropical cyclone Owen looking to reform in the Gulf of Carpentaria and the potential for widespread rain showers and thunderstorms across parts of eastern Australia. Ex-tropical cyclone Owen crossed the Queensland coast near Port Douglas around 3 am overnight and did bring some heavy rain and damaging wind gusts to parts of the north tropical coast. Kirrama Range saw 349 mm in the 24 hours to 9 am (that’s west of Cardwell) and at Bilyana (between Tully and Cardwell) 92 mm of the 239 mm recorded fell in just 60 minutes. Wind gusts of 87 km/h were seen that both Cairns Airport and Innisfail Airport as Owen approached the coast. We did see some trees down at Yarrabah as well. Heavy rainfall is likely to continue about the north tropical coast today and a Severe Weather Warning is still current; and a flood watch is in place as well. The low will continue to move westwards across northern Queensland during Monday and we should see it pop out into the Gulf of Carpentaria during early Tuesday. At this stage we
may see Owen re-intensify towards cyclone strength into early Wednesday, so if you’re living around the coasts of the Gulf of Carpentaria make sure to keep an eye on official Bureau cyclone Watches and Warnings as they’re issued from this afternoon. Towards midweek there’ll be another weather system to watch: This cold front way down south, here we go. There it is. It’s going to bring a cold air mass into southeastern Australia, which will meet a warm, humid air mass already in place. That’ll lead to the formation of this low pressure system. What we do know at the moment is that this low pressure system development is looking likely and most of our computer models are showing good agreement on the low forming either over Victoria or southern New South Wales during Thursday, but what we don’t know yet is exactly how much rain it might bring or exactly where the heaviest falls may be. Low pressure systems like these are always dynamic and often difficult to predict. There is the potential, though, for widespread showers and thunderstorms—possibly severe for some— and rain in some areas during both Thursday and Friday across much of eastern and southeastern Australia. So today it’s definitely a ‘heads up’ message on this weather system, with the expected rainfall totals to become clearer over the next day or two. With so much happening this week, make sure to stay tuned to the Bureau’s website for the latest forecasts and warnings, and follow all advice from emergency services.
