The forecast path shown above is the Bureau's best estimate of the cyclone's future movement and intensity. There is always some uncertainty associated with tropical cyclone forecasting and the grey zone indicates the range of likely tracks of the cyclone centre.
Due to the uncertainty in the future movement, the indicated winds will almost certainly extend to regions outside the rings on this map. The extent of the warning and watch zones reflects this.
This product is designed for land-based communities; mariners should read the coastal waters and high seas warnings.
Remarks:
CYCLONE BIANCA EXPECTED TO IMPACT COMMUNITIES IN THE SOUTH WEST OF WESTERN AUSTRALIA ON SUNDAY
Bianca will weaken significantly before it reaches the South West but residents should prepare for:
. DAMAGING WINDS with gusts to 120 kilometres per hour.
. VERY ROUGH SEAS and DANGEROUS SURF CONDITIONS
. COASTAL EROSION and FLOODING OF LOW LYING COASTAL AREAS
. SEVERE to EXTREME FIRE DANGERS
. HEAVY RAINFALL south of the cyclone with possible LOCALISED FLOODING.
Severe Tropical Cyclone Bianca continues to move in a southwest direction away from the northwest of the state. Strong and gusty winds are still possible in areas between Cape Preston and Carnarvon though winds will ease from the east during the day.
Severe Tropical Cyclone Bianca is expected to gradually weaken as it takes a more southerly track overnight. On Saturday Bianca will move in a southeasterly direction towards the southwest corner of the state while weakening steadily. However there is a significant risk that Bianca will maintain tropical cyclone intensity as it approaches the coast early on Sunday. If this happens, coastal areas between Jurien Bay and Albany could experience DAMAGING WINDS with gusts to 120 kilometres per hour. Wind gusts to 100 kilometres per hour may be experienced through inland parts southwest of a line Jurien Bay to Albany.
On Sunday tides between Jurien Bay and Cape Naturaliste are likely to rise significantly above the normal high tide mark with VERY ROUGH SEAS, DANGEROUS SURF and FLOODING of LOW LYING COASTAL AREAS. SIGNIFICANT COASTAL EROSION is possible. HEAVY RAINFALL is also possible on the southern side of the system. LOCALISED FLOODING is possible but extensive flooding is not expected.
VERY HIGH to SEVERE FIRE DANGERS are likely near the west coast on Sunday. EXTREME to CATASTROPHIC FIRE DANGERS are likely across inland areas south of a line from Geraldton to Leonora to Israelite Bay on Sunday.
FESA State Emergency Service (SES) advises that people should start planning for bad weather and listen for further advice during today.
