A new map shows Cyclone Uesi's predicted path of destruction towards New Zealand.
Metservice posted the map on Twitter on Wednesday evening to show the possible ways Uesi could travel towards the South Island.
The map was created with ensemble forecasting, which uses a group of weather models to predict the forecast outside six or seven days. The average result of the group of models is usually accurate.
The map shows the cyclone heading towards the bottom of the South Island after it sweeps across the ocean.
Currently, Tropical Cyclone Uesi is at "severe category 3" status and heading towards New Caledonia. It's expected to bring damaging wind, torrential rain causing flooding and dangerously high swells to the island.
After that, it's forecast to track into the Tasman Sea before brushing the Southern end of New Zealand.
While New Zealand may not bear the full brunt of the storm, it could bring some pretty terrible conditions.
"It's a little uncertain at this point, but it looks like Fiordland, Westland and Southland can expect some pretty heavy rain," meteorologist Paul Ngamanu told Newshub.
He says the cyclone will touch down on Sunday night, but as for how long it will stay, it's too early to tell.
