15 March - Reef Health update

Tropical cyclone Trevor

Tropical cyclone Trevor crossed through the Marine Park, making landfall on the Queensland coast south of Lockhart River as a category three system on 19 March 2019.

The system brought destructive winds and heavy rains to the far northern Marine Park.

Flood warnings were issued for the Daintree and Mossman rivers, as well as a broader flood watch for catchments north of Innisfail to Kowanyama, on the Gulf of Carpentaria side of Cape York Peninsula in far north Queensland.

The Marine Park Authority is currently working with the Australian Institute of Marine Science to generate a predictive model of the likely wave damage to coral reefs as a result of the cyclone.

El Niño

The ENSO outlook has moved from El Niño WATCH to El Niño ALERT — chance of El Niño developing in 2019 has increased to approximately 70 per cent.

In Australia, El Niños are usually associated with reduced rainfall and warmer temperatures.

The Bureau of Meteorology provides detailed information on what an El Niño could mean for Australia.
