With bad weather forecast for the top of the South Island tomorrow (Monday), drivers will need to take extra care on the roads.
The Metservice has issued a heavy rain watch for multiple regions across the top of the South Island.
They include Tasman - west of Motueka, Buller, the Bryant and Richmond ranges near Nelson, and the Rai Valley.
Periods of heavy rain are forecast for these areas from Monday morning to Monday afternoon.
It will affect State Highway 6 - from Rai Valley through Nelson to St Arnaud, State Highway 63 - St Arnaud to the Upper Wairau Valley, and State Highway 60 - Tākaka Hill through to Collingwood.
It means there is an increased risk of localised flooding, slips, rock and treefalls across the state highway networks in these regions.
Road users should drive to the conditions, use their headlights if visibility is poor, and watch their speed and following distances.
Drivers should be prepared for hazards. They should also check road conditions and weather alerts before they travel. Bad weather, slips, and flooding can see State Highways closed at short notice.
