Tropical Cyclone Amos is now a category two system and about 250 kilometres west-northwest of Wallis Island.
According to RNZI, the cyclone is moving east-northeast at nine kilometres an hour and is intensifying.
On its current track, the cyclone is expected to pass just south of Samoa overnight Saturday.
The latest storm warning from the Fiji Weather Office said early Friday morning winds of up to 90 kilometres an hour could be expected at the storm's centre.
Earlier today Amos did a U-turn and began heading towards Wallis.
It was expected to tend southeasterly by Saturday.
