A polar vortex has led to snow and thunderstorm watches being issued for much of the motu by MetService today, as a chilly blast springs into action.
This afternoon severe wind gusts closed lanes on the Auckland Harbour Bridge, with NZTA saying lanes will remain in 4×4 formation for the rush hour commute.
Drivers are warned to expect reduced speeds, lane reductions and possible temporary full closures.
Hail has been reported in Milford on Auckland’s North Shore, and in Snells Beach, north of the city.
