Description of the event

Cyclone Gita, a Category 4 storm, is heading towards Tonga after causing widespread damage in the neighbouring island of Samoa. The Tongan government has declared a state of emergency as the archipelago waits for the storm to hit.

Gita is expected to intensify to a Category 5 storm, the highest on the Saffir-Simpson Scale, before impacting Tonga, and is then expected to move towards Fiji, Vanuatu and New Caledonia over the coming days.

Evacuation centres have been set up on the islands of Tongatapu, Vava'u, Ha'apai and ‘Eua. The storm is expect to make landfall during the night, adding further concerns for residents safety. It has already affected Tonga's power supply, with authorities confirming that all of Tongatapu is without power.
