Systems
Severe Tropical Cyclone Alice–Adelaide
Formed on 3 November, just south of Selat Mentawai then moved southwestward before reaching a peak intensity of 110 knots (130 mph; 200 km/h) and a minimum pressure of 940.0 hectopascals (27.76 inHg) on 8 November. On 12 November the storm began to move northwestward and two days later dissipated over the open Indian Ocean.
Severe Tropical Cyclone Bert–Christelle
The origins of Cyclone Bert–Christelle can be traced to a quasistationary convergence zone that spread across Indonesia to north of the Cocos Islands. Bert–Christelle was slow to organize but began to show signs of organization on November 26. Later on that day, the disturbance gained sufficient organization, noted by curved cloudbands, to be classified as Cyclone Bert. The cyclone moved to the southwest, gradually intensifying and attained a peak intensity of 150 km/h (95 mph) and a barometric pressure of 965 hPa (28.49 inHg) on November 29. Bert continued the same westerly motion and exited the basin on December 3. It was subsequently named Christelle by Météo France.
