Vanuatu’s own meteorological service is still low-key about the two potential cyclones near Vanuatu, and is not tracking the tropical depression between Solomon Islands and New Caledonia.

VMS says the chance of the other system, Tropical Disturbance 09F, turning into a cyclone is between 10% and 60% likely within 24 hours.

However, The US Navy’s Joint Typhoon Warning Center says that “the development of a significant cyclone within 24 hours is high” for both systems. TD09F is currently travelling in a south-easterly direction, several hundred kilometres east of Maewo.
