Tropical Cyclone Guillaume developed east of Madagascar and initially tracked northeast then east as it intensified (see track below). The cyclone eventually made a southward turn to the east-northeast as it steered around a mid-level ridge of high pressure.
Guillaume attained maximum intensity (maximum sustained winds of 215 km/h, gusts up to 260 km/h) as it passed within 150 km of Mauritius while moving southward. Subsequently, the cyclone began to move more southeastward while undergoing transition to an extratropical storm. Fortunately, minimal damage and no casualties were reported from Mauritius.
Animated infrared images from Meteosat-5 indicate a 15–20 km irregular eye with deep convection around the centre. It should be noted that the eye of the cyclone does not follow a straight path, but performs a spiral movement, this behaviour has been observed in other Tropical Cyclone cases.
Meteosat-5, operating at 63 °E and providing EUMETSAT's Indian Ocean Data Coverage Service, plays a key role in tracking and predicting the path of Tropical Cyclones in the Indian Ocean. This service has been extended until the end of 2005.
