Weather Situation – Northern Western Australia
A broad trough lies over the Kimberley and Pilbara and will be pushed towards
the Pilbara coast as a high pressure ridge strengthens over the central west
coast over the next couple of days. A tropical low is moving west-southwest
offshore from the north Kimberley coast and is forecast to gradually intensify,
likely reaching cyclone intensity later Tuesday. The system is expected to
intensify further over the following days as it moves along a general track
parallel to the Kimberley coast. There is a significant risk that this system
will become a severe tropical cyclone on Wednesday and cross the coast between
Broome and Port Hedland later Thursday or early Friday.
Weather Situation – Southern and Central Western Australia
A cold front is moving over eastern and southern parts of the State and further
into the Bight. A high pressure ridge will strengthen over the central west
coast on Tuesday with a weak cold front brushing the southwest corner. Another
cold front is forecast to move over the southwest of the State on Thursday.
