There is currently a moderate likelihood of a Tropical Cyclone developing in the Northern Region on Tuesday 14th. A weak tropical low is located over the Arafura Sea, north of the Arnhem District, approximately 450km northeast of Darwin. The low is expected to remain over the Arafura Sea for the remainder of today, while tracking in a WSW direction towards the Cobourg Peninsula during tomorrow. On Tuesday, the low is expected to be located near the Tiwi Islands about the northwest Top End of the Northern Territory and has a moderate chance of developing into a Tropical Cyclone in the evening. If the low develops into a cyclone it will be the fourth so far this cyclone season. From Wednesday, the low or cyclone may continue in a southwest direction towards Western Australia's Kimberley region. Heavy rainfall and very strong winds are likely in the coming days across the NT's Top End and WA's Kimberley. For some areas within these regions, four day accumulated rainfall totals are likely to be greater than 300mm. In the event of severe weather, always heed the advice of emergency services.
