Karla moved into the Western Region from the Mauritius area of responsibility at about 0600 UTC 30 April with an estimated central pressure of 954 hPa and estimated winds near the centre of about 160 km/h.
Satellite photographs on the 30th showed a well defined eye, with significant cirrus outflow. As the cyclone moved steadily southeast on 1 May, it came under the influence of a westerly trough and most of the cloud sheared away from the low level circulation. Karla finally dissipated on the 4th over cold water.
Karla occurred west of 90°E when the Australian region extended to 80°E.
