MetService Issues Auckland Thunderstorm Watch as Torrential Downpours Hit Region

An Auckland thunderstorm watch has been issued as powerful storms move south from Northland, bringing heavy rain and lightning to the region. MetService has alerted several communities to possible torrential downpours and flash flooding. The latest weather threat could also disrupt travel across Tamaki Makaurau today.

Auckland Thunderstorm Watch Issued as Storms Approach

Auckland faced renewed severe thunderstorm activity on Friday afternoon, November 6, as a band of storms moved southeast from Northland. 

MetService issued a severe thunderstorm warning for Kaipara and several Auckland areas at around 3 p.m., following radar observations of developing storm cells.

The warning included Auckland City, Waitākere, Franklin, Rodney, the Gulf and Albany. 

Forecasters warned that the approaching thunderstorms could bring torrential rain, creating a risk of surface flooding and dangerous conditions on local roads.

The weather system had already brought substantial rainfall to parts of Northland earlier in the day. 

Radar observations around 2 p.m. showed the rain band moving south, with heavy falls around Doubtless Bay, inland from the Bay of Islands and near Kaipara Harbour.

Pawarenga, in North Hokianga, recorded approximately 30 mm of rain in one hour up to 1 p.m., according to Northland Regional Council data. 

Heavy rainfall was also reported near Hakaru, Kaiwaka and the Pouto Peninsula.

As the storm system approached more populated areas, residents faced an increased risk of sudden downpours and rapidly changing conditions.

Intense Downpours Put Roads and Low-Lying Areas at Risk

MetService warned that severe thunderstorms could produce localized rainfall rates of 25–40 mm per hour. 

Rainfall at this intensity can quickly overwhelm drainage systems, particularly in urban neighborhoods with limited capacity to handle sudden water accumulation.

Streams, gullies, narrow valleys and low-lying roads are especially vulnerable to surface flooding.

Heavy rain can also saturate the ground, increasing the possibility of slips in susceptible areas.

Travel conditions may deteriorate quickly during intense thunderstorms. Poor visibility, standing water and sudden flooding can make driving particularly dangerous. 

Motorists should reduce their speed, maintain a safe distance from other vehicles and avoid crossing flooded roads.

Lightning is another concern as thunderstorms pass through the region. Residents should seek shelter indoors, stay away from exposed locations and avoid standing beneath trees during electrical storms.

Use RadarMap to check live precipitation radar, rainfall intensity and storm movement. 

Further Thunderstorm Watches Extend Into Saturday

The severe weather threat is not limited to Friday afternoon. 

MetService has maintained broader thunderstorm watches covering Northland and Auckland through Friday evening, with another alert period expected to affect a wider part of the North Island on Saturday.

The Saturday outlook carries a moderate risk of thunderstorms becoming severe, with localized downpours potentially reaching 25–40 mm per hour. 

Flash flooding, slips and hazardous driving conditions remain key concerns.

Residents should monitor MetService updates because warning areas and expiry times can change as storms develop. 

Before heading outdoors, people should secure loose items, check drains where safe and prepare for sudden rainfall.

With further thunderstorms possible overnight and into Saturday morning, staying informed and allowing extra time for travel will be important across the affected regions.
