People living along Fiji's southern and and south-western coastal areas have been on high alert since last night following a warning that they could be hit by very damaging sea swells.
They've been advised to take every precaution to protect their lives and property.
Suva harbour, the Coral Coast along southern Viti Levu and the islands of Kadavu have been identified as high risk areas that could be lashed by waves ranging from 6 to 8 metres high.
People have been advised not to put to sea or be close to beaches and low ground.
Those living in these areas have been told to seek shelter.
Navy personnel have been recalled to stand by for search and rescue operations, the disaster management offices in Suva and Lautoka have been activated and the Suva City council is monitoring the situation.
Most commercial shipping services have been cancelled and small boats and yachts have been moved to safe areas.
