A tropical cyclone is likely to form off the north coast of WA in a matter of days, with signs that it could become a severe tropical cyclone next week.
A tropical low is currently developing over the Timor Sea to the north of Darwin. The circulation centre of this developing low can be clearly seen in the satellite images below, sitting just south of Indonesia’s Babar Islands on Friday morning.

The tropical low is expected to move towards the southwest this weekend and early next week, likely gaining strength as it traverses the warm waters off WA’s north coast.
According to the Bureau of Meteorology’s forecast track map issued at 9:02am AWST on Friday, the low is expected to become a tropical cyclone on Saturday and continue to strengthen on Sunday and early next week, possibly becoming a category three severe tropical cyclone by Tuesday.
At this stage, the impending tropical cyclone is not likely to cross the coast and should stay to the north of WA between now and at least the middle of next week. However, it could still get close enough to the Kimberley coast to cause damaging winds, heavy rain and abnormally high tides this weekend and early next week.

Tropical cyclones are notoriously difficult systems to predict, particularly when they are still tropical lows and in the early stages of tropical cyclone development. Forecasts may change in the coming days as the system develops further and more reliable model guidance becomes available.
Unless another tropical cyclone forms in the Australian region before this one – which is unlikely at this stage – the impending cyclone will be named Errol.
Should this system reach category three strength, it will become the 8th severe tropical cyclone in the Australian region so far this season. This would be the highest number of severe tropical cyclones in a single season for 19 years.
