Cyclone Lam was the strongest storm to strike Australia's Northern Territory since Cyclone Monica in 2006. It formed from the monsoon trough on February 12 in the Coral Sea. For much of its duration, the system moved westward due to a ridge to the south. The system crossed over the Cape York Peninsula and moved into the Gulf of Carpentaria, whereupon it gradually organized due to warm waters and favorable outflow. On February 16, the Bureau of Meteorology (BoM) classified it as a Category 1 on the Australian tropical cyclone intensity scale and gave it the name Lam. The storm intensified further while drifting toward the Wessel Islands, developing an eye and strengthening to the equivalence of a minimal hurricane on February 18. It strengthened to reach maximum sustained winds of 185 km/h
