Drivers in the top of the South Island will need to be ready for challenging driving conditions tomorrow as bad weather moves up the country.
The Metservice has issued heavy rain warnings for Tasman, west of Motueka, and the Bryant and northern Richmond Ranges near Nelson.
They apply from midday Friday to midday on Saturday, with up to 150 mm of rain forecast.
The wet weather comes with the start of the school holidays and a time when there is likely to be more traffic on the roads.
It means drivers, particularly those using State Highway 6 near Nelson and State Highway 60 to Tākaka, should take extra care on the roads.
This means watching your following distances, having your headlights on if visibility is poor, and staying alert to possible road hazards. Heavy rain can cause slips, treefalls and localised flooding.
Road users are encouraged to check weather and road conditions before they travel, as bad weather can see state highways closed at short notice.
