A tropical low formed to the northwest of the Cocos (Keeling) Islands on 12 January near the boundary between the Australian and TCWC Jakarta Area's of Responsibility. It gradually intensified over the following days, reaching tropical cyclone strength on 15 January in the TCWC Jakarta Area of Responsibility and was named Anggrek.
Anggrek proceeded to move steadily south while remaining at or near category 1 intensity. It entered the Australian Area of Responsibility on January 17 and passed to the west of the Cocos (Keeling) Islands. On 18 January it started moving much slower and to the west while intensifying further. Anggrek reached category 2 intensity on 19 January, but then weakened back to a tropical low on 22 January.
Anggrek then started moving due south before moving southwest and strengthening back into a tropical cyclone on 23 January. It intensified rapidly on 24 January into a category 3 tropical cyclone, reaching a peak intensity that night and maintaining its intensity as it moved into RSMC La Reunion Area of Responsibility the following day.
