Summary
During an active phase of the Madden-Julian Oscillation (MJO), a monsoonal low pressure system developed in the Indian Ocean, near 6 o S 99 o E on 6 April 2013. The low then moved to the southeast and developed into a tropical cyclone on 9 April, despite environmental conditions being only moderately favourable. Victoria rapidly intensified to Category 3, reaching peak intensity during 10 April.
Victoria moved at a reasonably fast and consistent pace towards the south southeast, passing between the Cocos Keeling Islands and Christmas Island. Overnight on 11 April, Victoria weakened rapidly below tropical cyclone intensity due to unfavourable conditions in the upper atmosphere and lower Sea Surface Temperatures (SSTs). The tropical cyclone had no direct impact on the Cocos Keeling Islands, Christmas Island, or the West Australian mainland.
