At 2pm WST 23 February a weak tropical low (15U) was located near 13.3S 120.9E, about 540 kilometres north northwest of Broome. It is expected to track to the west and gradually develop, and by Friday there is a high chance of it reach tropical cyclone intensity.
It will move to the south of Christmas Island during Friday, and although it is unlikely to produce gales at the Island, it will result in an freshening of the northwesterly monsoonal flow, and an increase in shower and thunderstorm activity. It should then continue to develop over the weekend, well the the northwest of mainland WA.
Likelihood of this system being a tropical cyclone in the Western Region on:
Wednesday:Very Low
Thursday:Moderate
Friday:High
