A pair of tropical cyclones may form to the northwest of Australia next week, with the potential for one to come close to the Pilbara and Kimberley coasts.
Northern Australia faces an increased risk of heavy rain and tropical cyclone activity in the coming week thanks to the interaction of two huge atmospheric waves near Australia.
In response to these tropical waves, two tropical lows are forecast to form in the Indian Ocean to the northwest of Australia in the next few days.
The first tropical low (04U) will form near west Java in the coming days and the Bureau of Meteorology has given it a moderate risk of developing into a tropical cyclone on Sunday. The system will move southwest towards the Cocos (Keeling) Islands next week, increasing showers and thunderstorm activity in the region. The cyclone at this stage will stay well away from Australia’s mainland.
The second tropical low is expected to form over the Timor Sea or south of Indonesia in the coming days and has a moderate risk of developing into a tropical cyclone on Monday, December 9 as it moves over favorably warm oceans.

According to the Bureau, this system could move west southwest towards the waters off WA’s Pilbara district early to mid-next week.
Some other international forecast organisations also show a strong possibility of tropical cyclone development near WA early to mid-next week. The image below shows the likelihood of tropical cyclone activity within a 48-hour window of Wednesday night, according to the European Centre for Medium-Range Weather Forecasts (ECMWF),

The image above shows that there 10 to 30 percent chance of the cyclone passing within 300km of the Pilbara and Kimberley coasts mid next week.
Depending on how close the system moves to the coast, the Pilbara and Kimberley could see an increase in wind, rain and thunderstorm activity next week.
