Nil.
Potential Cyclones:
A tropical low (11U) was located near 13S 105E at 1pm WST Saturday, which is about 300 km south southwest of Christmas Island. The low is weak at the moment and unlikely to develop over the next three days. The system is forecast to continue moving westwards and is very unlikely to move close to the West Australian coast. On Sunday or Monday it might move close to the Cocos Islands bringing a period of fresh to strong winds and periods of heavy rainfall.

A trough lies across waters north of the Kimberley and Northern Territory. A weak tropical low is forming within the trough north of the Northern Territory and is forecast to move generally southwest over the next few days, possibly moving into the region in the middle of next week. The risk of this system developing into a tropical cyclone increases further later in the week.
