Several more bouts of wintry weather are expected for the South Island this week, according to forecasts; raising the prospect of further highway closures and disruption for road users.
Following a series of recent closures due to snowfall, the MetService says a front moving northward tomorrow (Tuesday) over the South Island will drop the snow level to around 600-700m in the south of the island and to around 800m in central parts. Road snow warnings are in effect for SH73 Arthur’s Pass, SH8 Lindis Pass, the Crown Range Road and SH94 Milford Road, as well as snow alerts for SH8 Kimbell to Twizel and SH6 Kawarau Gorge. There is a low risk of snow settling for SH7 Lewis Pass.
Potentially heavy rain, thunderstorms and hail are also possible in parts tomorrow.
Another front on Thursday may bring further snow risks in a westerly flow over the South Island, but at this stage doesn’t look as cold or intense as Tuesday, MetService says. However, snow may still be possible about Arthur’s and Lewis Passes depending on the timing of the precipitation and the colder air, with lower risks for Burke’s and Lindis Passes as well as the Crown Range.
A cold southerly change is also due to move up the South Island later on Friday into Saturday, with the potential to bring snow as low as around 500m in the east and south of the South Island.
New Zealand Transport Agency Waka Kotahi (NZTA) and its road crews are gearing up to respond to further snow dumps affecting state highways at higher elevations around the South Island.
“As is often the case as we move into spring, the weather can be highly changeable and can still pack an icy punch,” says NZTA journey manager for the lower South Island, Nicole Felts.
“Our message to people using the state highways at higher elevations is to plan ahead by knowing the conditions and be prepared for disruption such as road closures or delays. Adjusting your driving to the conditions is also critical to keeping you and other road users safe. Make sure you are visible, reduce your speed, adjust your travelling distance behind other motorists and avoid sudden braking or turning movements.”
SH94 Milford Road is currently open but is due to close today at 5pm between Hollyford Road Junction and Donne River Bridge because of overnight snow forecast and an elevated avalanche hazard. The road is expected to reopen mid-morning tomorrow and to remain open through until Wednesday. Further travel disruption and closures are possible from late Wednesday.
