Following a period of heightened convective activity in the monsoon trough in late February, a clearly defined centre was identified near 17°S, 115°E on 2 March. This low with a central pressure of 997 hPa slowly deepened and moved southwest. It attained tropical cyclone intensity with a central pressure of 993 hPa at 1200 UTC 2 March near 17.8°S, 113.4°E.
Vincent continued to move steadily south to southwest and to intensify. An eye became visible on satellite imagery after 0900 UTC 3 March and peak intensity was reached around 0000 UTC 4 March when the central pressure was estimated to be 966 hPa and the maximum mean wind to be 176 km/h.
By 0000UTC 5 March, an approaching cold front over the eastern Indian Ocean caused Vincent to accelerate first in a southerly and later in a south-easterly direction. Satellite imagery revealed a rapidly decaying cyclone structure with the upper and middle-level cloud being sheared away from the low-level centre.
By 0001 6 March, Vincent was 200 km west-southwest of Cape Leeuwin and moving southeast at 60 km/h. The 991 hPa low-level centre was devoid of cloud but gales were still being reported along the coastal strip.
Vincent rapidly moved over cold water and dissipated
