Ula is now a Category Three cyclone and is easing as it moves in a south easterly direction from its position south of the Vanuatu group.
Ula reached Category Four level as it veered towards Vanuatu's south at the weekend raising fears for vulnerable islands in Tafea Province which are still recovering from the devastation of last year's Cyclone Pam.
Aid agencies report the islands have been left mostly unscathed.
Oxfam's country coordinator in Vanuatu, Colin Collett van Rooyen, says there are reports of minor flooding and damage to some food crops.
There are also reports of very high seas.
