Over the following three days, the system gradually developed into a tropical cyclone as it tracked towards the southeast. On 18 October, a ship named Alkuwait encountered the storm and reported winds near hurricane-force; however, the satellite presentation of the system was not supportive of these winds. Later named Marcia, the storm is estimated to have attained peak winds around 85 km/h mph on 5 on 20 October.Bureau of Meteorology 2011 3 February 2011 Tropical Cyclone Marcia http://www.bom.gov.au/cyclone/history/marcia74.shtml Around this time Marcia also attained a barometric pressure of 989 mbar (hPa; 29.2 inHg).Bureau of Meteorology 2011 3 February 2011 Tropical Cyclone Marcia 1974 Track http://www.bom.gov.au/tmp/aus197419741.html https://archive.today/20110411015533/http://www.bom.gov.au/tmp/aus197419741.html dead 11 April 2011 The following day, as the storm was situated 320 km mi on west-southwest of the Cocos Islands, the outer bands of Marcia brought unsettled weather to the islands.
