Tropical Cyclone Pedro

6 - 13 November 1989


A low pressure centre was detected in the monsoon trough near 7.8°S, 97.2° 0000 UTC 6 November. It slowly became more organised and drifted in a general westerly direction for the next 48 hours. Observational data indicate that gale force winds were well displaced from the centre of the circulation at this stage.

Maximum intensity was reached at 0600 UTC 10 November when the central pressure was 982 hPa and Pedro was at 12.4°S 95.5°E. The eye was briefly discernible on satellite imagery at that time. At about 1300 UTC 10 November, Pedro began a more southerly and later a south southwesterly track. Strong vertical shear exposed the low-level circulation to the northwest of the main convective cloudband and the cyclone weakened. By 0000 UTC 13 November, gales had subsided and the remnants had dissipated by 0700 UTC 14 November.

Pedro passed within 140 km of Cocos Island where the highest wind gust recorded was 137 km/h and the minimum pressure was 1000 hPa. Structural damage to the loading wharf and light damage to a palm plantation occurred. Two hundred and two millimetres of rain fell in 24 hours and local flooding was reported.
