IRC Public Notice - Tropical Cyclone Advice 36

Severe tropical cyclone Debbie, category 4, is approaching the Whitsunday Islands.

Severe tropical cyclone Debbie is currently a category 4 cyclone and is forecast to make landfall between Ayr and Midge Point late this morning. Isaac’s coastline to St Lawrence and Moranbah remain in the warning zone in the latest advice issued at 5am today.


  • The VERY DESTRUCTIVE CORE of tropical cyclone Debbie is now starting to impact the Whitsunday Islands and the centre of the system is forecast to cross the coast between Ayr and Midge Point later this morning with wind gusts potentially to 260 km/h near the centre.

  • DESTRUCTIVE WINDS with gusts over 125 km/h are occurring about the Whitsunday Islands, and will extend further to the coast and islands between Ayr and Sarina during this morning. These DESTRUCTIVE WINDS may extend further south along the coast to St Lawrence today.

  • GALES are now occurring about the Whitsunday coast and south to Sarina. These GALES are expected to extend to the remaining coastal and island areas between Townsville and St Lawrence later today. GALES could potentially extend further north to Lucinda and further inland to locations such as Charters Towers, Pentland, Mount Coolon, and Moranbah this afternoon and tonight.

  • Residents between Ayr and St Lawrence are specifically warned of the dangerous storm tide as the cyclone crosses the coast.

  • The sea is likely to rise steadily up to a level well above the normal tide, with damaging waves and flooding of some low-lying areas close to the shoreline as the cyclone approaches the coast on Tuesday. Large waves may also develop along the beachfront.

  • Heavy rain with potential for severe flash flooding have developed around the central coast and Whitsundays and are expected to spread to parts of the northern and central Queensland coast and adjacent inland areas today. Widespread daily rainfall totals of 150 to 250 mm, with isolated event totals of 500 mm, is likely to lead to major river flooding next week, and a Flood Watch is current for coastal catchments between Rollingstone and Gladstone.

Recommended Action: People between Lucinda and St Lawrence, and inland including Moranbah should immediately commence or continue preparations, especially securing boats and property.
