Hello from the Bureau, and welcome to your weather wrap for Sunday 8th March. We come now to the end of a wet week for northern and eastern Australia, thanks to Tropical Cyclone Esther. During the past week it tracked from northern WA through the NT, southwestern Queensland and then the eastern states, producing multi-day rainfall totals which in some areas exceeded 300mm, even once the TC had been downgraded to an ex-TC. This system has now broken up and moved offshore, with much more settled weather facing the southern states, thanks to the stabilising
influence of a high pressure system in the Bight. Things are still a little unstable across
northern Australia, however, with the monsoon trough continuing to produce showers and the isolated thunderstorms across the Top End, Cape York and eastern Queensland. Settled weather will continue through the
south as this week begins, with that high pressure system gradually moving towards Tasmania. We could also see some light showers across parts of the southern WA coast, western South Australia, and the southeast of the continent, but significant rainfall is not expected. That’s not the case across northern Australia, though, where we’ll see the monsoon trough becoming more active as the week progresses, particularly across the Gulf of Carpentaria and northern Queensland. This will enhance convective activity in these areas and by midweek, combined with high sea
surface temperatures and deepening low pressure, this could create favourable conditions for the development of a new tropical low or lows. While current model guidance suggests the north-east as a formation hotspot, with the possibility of a tropical cyclone forming
in the coral sea, we might also see another low approaching the Pilbara Coast. We’ll be tracking these systems closely given their potential and the uncertainty surrounding their exact development so make sure to keep an eye on that and all the rest of your weather forecasts and warnings on our website. Catch you next Sunday, bye for now.
