Two cyclonic systems form off Australia's northeast coast

Tropical Storm Olga formed overnight in the Coral Sea off the northeast coast of Australia. The Bureau of Metrology in Queensland has issued a cyclone WATCH from Cape Melville to Lucinda.

Olga currently has 100 kph winds and is heading on a westerly direction towards the coast. The current forecast is for Olga to strengthen before reaching landfall by late Sunday or early Monday.

Another system in the same area had been labelled as cyclone Neville. Neville formed and then quickly degraded back to a low pressure system. The area where Neville is located is not conducive to cyclone formation but this could change.

UPDATE: FORMER tropical Cyclone Neville has become an ex-cyclone after rapidly weakening off the far north Queensland coast.

The category one cyclone has been downgraded to a tropical low after "slipping below the meteorological threshold'' in the Coral Sea off far north Queensland.

"It's in an environment that's suppressing its development at the moment,'' said senior forecaster Ann Farrell from the Tropical Cyclone Warning Centre.

"There is the potential for it to possibly re-intensify as long as it remains over the water. It's a bit of a waiting and watching game.''
