MetService advise that severe thunderstorms are no longer expected in West Auckland but are possible in southern parts of the region this afternoon.
MetService says that cloud buildups are expected to produce scattered heavy showers and thunderstorms this afternoon and early evening.
These thunderstorms will be accompanied by localised heavy rain and hail.
A few of the thunderstorms may be severe producing localised downpours of 20-30mm/hr.
Rainfall of this intensity can cause flash flooding, especially about low-lying areas such as streams, rivers or narrow valleys.
Drivers are advised to take care as conditions will be hazardous with surface flooding and poor visibility in heavy rain.
