Ivan was the second Western Region cyclone. Little is known of this storm as it developed well away from regular shipping lanes in the Indian Ocean. It was monitored at irregular intervals by the meteorological satellites TIROS-N and METEOR 23. The satellite imagery suggests that Ivan was not intense. The estimated central pressure fell to about 988 hPa on 18 March 1979 when winds near the centre probably reached about 90 km/h. It is likely that gales were confined to within 100 km of the centre.
