Weather System Causes Flooding and Travel Warnings in South Island
What happened
A weather system brought warm spring temperatures to parts of the South Island, but surface flooding was reported on state highways in Westport and Greymouth. The NZ Transport Agency Waka Kotahi was alerted to flooding in Otago, specifically on State Highway 87 in Mosgiel and State Highway 83 between Oamaru and Kurow. Heavy rain watches remain for North Otago, Dunedin, and Clutha, and snow is expected later in the week, potentially up to 10cm at Porters Pass on SH73.
