Tropical Cyclone Gillian

9 - 12 February 1997


A tropical depression located within the monsoon trough in the Coral Sea formed rapidly into cyclone Gillian on 10 February. Its movement was towards the southsouthwest under the influence of a marked upper-level trough lying to the south of the system and a north/south oriented mid-level ridge to the east. As it approached the Tropical Upper Tropospheric Trough (TUTT) cell over northeast Australia, shear increased and weakened the system. By 12 February Gillian had weakened to become a tropical depression. The remnants of the cyclone continued to move in a southwesterly direction and crossed the coast in the vicinity of Townsville with little discernible effect.
