Cyclone Monica

On 20 April 2006, Monica emerged into the Gulf of Carpentaria and began to re-intensify. Over the following few days, deep convection formed around a 37 km (23 mi) wide eye. Early on 22 April 2006, the Bureau of Meteorology (BoM) assessed Monica to have attained Category 5 status, on the Australian cyclone intensity scale. The Joint Typhoon Warning Center (JTWC) also upgraded Monica to a Category 5-equivalent cyclone, on the Saffir–Simpson Hurricane Scale. The storm attained its peak intensity the following day with winds of 250 km/h (160 mph) 10-minute winds) and a barometric pressure of 916 hPa (mbar; 27.05 inHg). On 24 April 2006, Monica made landfall about 35 km (22 mi) west of Maningrida, at the same intensity. Rapid weakening took place as the storm moved over land. Less than 24 hours after landfall, the storm had weakened to a tropical low. The remnants of the former-Category 5 cyclone persisted until 28 April 2006 over northern Australia.


In contrast to the extreme intensity of the cyclone, relatively little structural damage resulted from it. No injuries were reported to have occurred during the storm's existence and losses were estimated to be A$6.6 million (US$5.1 million). However, severe environmental damage took place. In the Northern Territory, an area about 7,000 km² (2,700 sq mi) was defoliated by Monica's high wind gusts. In response to the large loss of forested area, it was stated that it would take several hundred years for the area to reflourish because of the large area it devastated.

Aftermath

The Queensland Government State Disaster Management Group dispatched relief helicopters to remote communities for evacuation of people in flood zones and transport of relief workers.^[24] Relief efforts were already underway in relation to Cyclone Larry which caused significant damage in Queensland. The Government of Australia assisted affected business by providing disaster loans up to A$25,000 for severely impacted areas and A$10,000 for less affected areas. Farmers were also provided with up to $200,000 in loans over a period of nine years.^[48] Following the impacts in the Northern Territory, two cleanup teams were dispatched from Darwin to assist in cleanup efforts in the hardest hit regions.^[24] Despite the minimal damage caused by Monica, the name was retired from the circulating lists of tropical cyclone names for the Australian Region.^[49]
