Track of TC 23P

Tropical Cyclone Zane (23P) surged in intensity yesterday as a boost in poleward outflow occurred simultaneously with a boost in gradient level flow due to an anticyclone moving off-shore of Queensland.

The system will remain in its current environment of 29 degree surface waters and 15-20 knots of vertical wind shear (VWS) through landfall over the Cape York Peninsula. Track guidance is in excellent agreement up to landfall. Guidance is also consistent that the system will remain weak once it emerges into the Gulf of Carpentaria.
