Unpredictable low forecast to become cyclone, may impact coastline, says BoM

Forecasters are watching a tropical low off the coast which is predicted to form into a cyclone and come closer to Australia.

METEOROLOGISTS are watching a tropical low located off the Western Australian coastline, with forecasts it will strengthen to a category one cyclone.

But the Bureau of Meteorology is warning of “uncertainty” in its forecast, with the storm expected to interact with another cyclone – Tropical Cyclone Seroja – in coming days.

The Bureau’s forecast path also suggests the storm, dubbed 23U, could come close to making landfall along the WA coast between Exmouth and Carnarvon.

It is forecast to be in the region by Sunday, although by then should weaken back to a tropical low.

“There is the risk of a period of damaging winds and heavy rain developing in the Exmouth area as early as Saturday, even though 23U is unlikely to still be at tropical cyclone intensity by this stage,” the BOM said.

The system, which is expected to intensify into a tropical cyclone late Thursday or early Friday, would still pack gale force winds.

The range of likely tracks includes the possibility of making landfall between Exmouth and Carnavon.

The storm, known by the BOM by the catchy name of “23U,” will also interact with Tropical Cyclone Seroja.

“There is likely to be interaction between 23U and the approaching Tropical Cyclone Seroja which is expected to limit development of 23U,” the BOM said.

“The interaction between the two tropical systems means there is a higher degree of uncertainty in the forecast track than usual.”
