TROPICAL CYCLONE WARNING CENTRE PERTH

A CYCLONE WATCH is now current for a tropical low for coastal areas between
Broome and Kalumburu.

At 2pm WST a tropical low was estimated to be
725 kilometres west northwest of Kalumburu and
740 kilometres north northwest of Derby and
moving west at around 12 kilometres per hour.

Though currently moving westwards it is likely that the low will turn sharply
towards the southeast on Monday and approach the Kimberley coast on Tuesday.

The low is currently very weak and poorly defined, however there is some limited
potential for it to develop into a tropical cyclone late on Monday. Should the
low develop into a tropical cyclone it is unlikely to reach more than Category
One intensity prior to impact on the coast.

Details of tropical low at 2pm WST.

Location of centre : within 170 kilometres of
Latitude 11.3 South Longitude 120.7 East.
