By the time it crossed into the Mauritius Tropical Cyclone Region it was a storm of moderate intensity and was continuing to deepen. On entering the Mauritius Region the cyclone's name was changed to Dance . It moved farther westward and on 21 and 22 January it affected Malagasy.
Terry occurred west of 90°E when the Australian region extended to 80°E.
