Over the next 24 hours starting from 8pm this evening, Invercargill and the broader Southland region in New Zealand are set to experience a range of weather conditions.
In Southland, temperatures are expected to reach a high of around 23°C. However, the region is under a strong wind watch for Fiordland south of George Sound, and Southland west of State Highway 6, including Stewart Island until 1 am on Thursday. During this period, north to northwest winds may reach severe gale force in exposed places. The high winds are part of a larger pattern affecting parts of the South Island, contributing to hot, dry, and windy conditions that are increasing the risk of wildfires in certain areas.
Additionally, there is a heavy rain warning in place for parts of the South Island, including Westland south of the glaciers and Fiordland north of Doubtful Sound. This warning is effective for 24 hours from 9 pm on Wednesday night as a front moves north. The region could see up to 200 millimeters of rain, with peak rates of 20 to 30mm per hour expected after dawn. The heavy rain is forecast to ease in Fiordland from midday on Thursday. The downpours might cause rapid rises in rivers and streams, leading to potential surface flooding and slips.
Residents and visitors in these areas should stay informed and prepared for these weather conditions, as they can lead to hazardous situations, including the risk of floods and wildfires. It’s important to follow local authority guidelines and weather advisories during this period.
