Thunderstorms

The risk of thunderstorms generally decreases during the day, but there is still a moderate risk of thunderstorms about parts of Northland, northern Auckland, the Hauraki Gulf (including Great Barrier Island) and Coromandel Peninsula this morning and afternoon.

A broader low risk covers other parts of the northern North Island as indicated on the chart. Any thunderstorms that occur will produce localised heavy rain of 10-25 mm/h, along with a low risk of one or two severe thunderstorms producing localised downpours of 25-40 mm/h.

A low risk of thunderstorms covers other parts of Auckland and Coromandel Peninsula from mid-morning.

Likely/potential Impacts

Rivers and lakes

Despite the recent dry weather allowing catchments to have plenty of storage, these downpours may cause rivers to rise rapidly causing localised flooding.

Land instability

Heavy rain has potential to impact localised areas. Areas that would normally experience land instability may be affected. Please keep up to date with the latest on state highway conditions from the NZ Transport Agency Waka Kotahi and city and district councils for local roading impacts.
