Once again a large "blob" of much warmer than normal ocean water in the tropics/subtropics increased available energy to cause a tropical cyclone to flourish and intensify while moving slowly to cause maximum damage due to a blocking subtropical ridge pole ward of the storm.

The atmosphere finally coupled with the equatorial East Pacific warming the past 7 weeks as demonstrated by a persistent negative phase of the southern oscillation index. The evolving El Nino climate helped to inspire heavy precipitation events.

The Bureau of Meterology/Australia annouces an EL Nino Alert today. Meanwhile 2 tropical cyclones are likely to cause damaging high wind and flooding to northeast/north and northwest portions of Australia.

Tropical Storm Trevor intensifies to a category 1 tropical cyclone and strikes northeast Australia tomorrow then weakens over land before re-emerging to the north of Australia later this week when strengthening to a category 2 tropical cyclone is possible before a scecond landfall.
