Summary
An out of season tropical low briefly reached cyclone intensity near 90°E but was not named operationally. Intensification was assisted by warmer than average sea surface temperatures exceeding 28°C, favourable low level shear and strong upper level outflow associated with the approach of a mid-latitude trough to the south.
The estimate of cyclone intensity being reached was strongly influenced by quickscat imagery rather than conventional Dvorak estimates. This was only the second tropical cyclone to be recorded in July in the Australian region since satellite records commenced.
There was no known impact from this event.
