NWP guidance is indicating two differing scenarios with regards to system movement, the favoured one moving SSW initially in the next 12 hours then turning more westerly during Friday. The other and less favourable scenario is for a westward movement during the next 24 hours. The possibility of gales affecting Rennell Island will decrease during the next 24 hours as Yani follows its current course.
