Auckland has a high risk of downpours that could reach up to 25mm per hour, something that has not been seen since 2017.
A series of weather alerts and alerts have been implemented for the North Island areas. A heavy rain warning is in effect for the Bay of Plenty and northern Taranaki areas throughout the day Wednesday.
Heavy rain alerts are in effect for the Coromandel Peninsula, Taupō, Taumarunui, Waitomo, Waikato south of Hamilton, and also for Tongariro National Park.
Clocks have also been installed for the Ruahine range and the Tararua range. On the South Island, there are weather alerts for Takaka Hill, Arthur Range, and Kaikōura Coast and Ranges.
The humid and stormy weather that spans the entire country is due to the deepening of the lowland and its associated fronts that have moved across the islands from the Tasman Sea.
During Wednesday morning there is a moderate risk of thunderstorms from Northland to north Taranaki, including the Coromandel Peninsula and the Bay of Plenty west of Tauranga, MetService warns.
Stormy weather is expected to continue Wednesday afternoon, with moderate risk of thunderstorms for the Coromandel Peninsula, the Bay of Plenty coastline, western Gisborne, inland Hawke’s Bay, Whanganui and inland Manawatū .
There is also the possibility of severe thunderstorms for the North Central Island, with stormy weather forecast in Waikato, the Bay of Plenty and Tongariro National Park.
These thunderstorms can produce localized rainfall rates of 10mm to 25mm per hour, the forecaster warns.
