Much of Fiji is now under curfew as it awaits Cyclone Evan - which is threatening to become a devastating category five storm.

Radar pictures show that Evan, which devastated Samoa on Thursday night, is about to hit Fiji tonight and into tomorrow.

It is not known what happened to the 15,000 people of the French islands of Wallis and Futuna, which Evan passed over today.

The upgrade came as Evan was on top of Wallis Island, part of the French territory of Wallis and Futuna. The islands, the only kingdoms within the Republic of France, are now completely cut off.

Authorities there usually take down satellite dishes as cyclones pass over.

The military commissioner for Fiji’s northern district, which includes Vanua Levu, Colonel Ilai Moceica, this afternoon imposed a curfew, saying it was necessary to save lives.

Meanwhile the Fiji Navy has warned all seafarers that travelling during disasters not only threatens the lives of those at sea, but also the Fiji Navy.

The latest warning from the Fiji Meteorological Service has issued storm and gale warnings across a wide area of Fiji, including the Yasawa and Mamanuca areas, popular with tourists.

All tourists at island resorts off the western coast of Viti Levu have been evacuated to the Nadi area. The service is warning that “destructive winds” may begin several hours before the cyclone centre arrives around midnight.

Weather forecasters are predicting that super cyclone Evan will hit New Zealand's Northland and Auckland area toward the end of the week.

Samoa, which was savaged by the storm on Thursday night, has four confirmed dead and eight people missing from fishing boats.
