A large low over the Tasman Sea is expected to begin moving slowly onto the country during Saturday. Humid and unstable conditions continue in many places.

There is at least a low risk of thunderstorms over all the North Island and northern and western parts of the South Island today, but especially this afternoon and evening.

For the north and central parts of the North Island, there is a moderate risk of thunderstorms from afternoon. These thunderstorms may produce localised heavy rain with intensities of 10 to 25 mm per hour and medium size hail. There is a low risk of these thunderstorms becoming severe about Northland, Auckland, eastern Waikato, Coromandel Peninsula, Bay of Plenty, also the ranges of northern Hawke's Bay and Gisborne, with downpours of 25 to 40 mm per hour.

For Whanganui, Manawatu, Horowhenua, Wairarapa including the Tararua District, and parts of Kapiti and Wellington, as well as Buller, inland and western areas of Nelson and Marlborough, inland in the north of Westland and northern Canterbury High Country, there is a moderate risk of thunderstorms this afternoon and evening, bringing localised heavy rain with intensities of 10 to 25 mm per hour and medium sized hail.
