Strong winds are already having an impact in the central South Island, with fallen trees on state highways and road signage repeatedly blown over. 

NZTA Waka Kotahi spokesman Jarrod Booker said contractors had been called out several times throughout the South Island to clear fallen trees and debris from state highways. 

Road signs have reportedly blown over on the stretch of State Highway 8 between Twizel and Fairlie, where an area warning is now in place because of strong winds.

Heavy rain warnings are also in place for headwaters of Canterbury lakes and rivers, Westland ranges north of the Haast River, the Grey District and Buller. 

Wondering what’s happening to that front over the South Island?🤔

The front currently over central South Island – with associated heavy rain🌧💧 – continues its northward trajectory to northern parts of the island by the end of the day⬆️

The worst of the rain is expected to clear by tonight as it moves north. 

Road snowfall warnings are also in place for Lindis Pass (SH8), the Crown Range Rd and Milford Rd (SH94), where 5-10cm may accumulate about the highest parts with lesser amounts down to 600m.

Road users are reminded to travel with extra care in adverse weather conditions.
