The system is in a favourable environment for further intensification during Sunday night until Tuesday where it is expected to reach a category 2 system. During this time it is forecast to track towards the South – South East with a likely track to the East of Vanuatu as this time. Squally showers and thunderstorms with wind gusts to 70km hr are possible across the Vanuatu Island group during the next 3 days provided the system maintains its forecast track. During Wednesday global models indicate the system will encounter strong Vertical Wind Shear and drier mid level humidity thus rapidly weakening it below TC strength.
