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:

Remarks:

SEVERE TROPICAL CYCLONE JONICA, CATEGORY 3, is now expected to cross the coast near the Gold Coast tomorriow afternoon.
VERY DESTRUCTIVE WINDS are currently within 30 kilometres of the centre and
DESTRUCTIVE WINDS extend 55 kilometres out from the centre.
GALES extend 130 kilometres out from the centre and are possible between Double Island Point and Coffs Harbour

- People in the path of the very dangerous cyclone should stay calm and remain in a secure shelter - above the expected water level - while the very destructive winds continue.
