Weather update: thunderstorms entail a risk of lightning and flooding

Thunderstorms are still expected this afternoon by hitting Auckland, bringing hail, heavy rain and strong gusts of wind.

The heavy weather sneaks in from the west and is expected to move to South Auckland.

Thunderstorms come in a repeating line over that area, with danger of lightning and flooding, WeatherWatch has reported.

It is expected that heavy downpours will drop over the western and central parts of the North Island in the coming days, when a complex low-pressure system slowly moves across the country.

A heavy rain watch is in effect for some western regions of the North Island until 6 a.m., because eruptions of heavy showers can mean that accumulations can reach warning criteria, reported MetService.

There was a moderate risk of thunderstorms in the wider areas of rain over the western parts of Northland, Auckland, Waikato and Waitomo in the afternoon, as well as the eastern Bay of Plenty in the afternoon and early evening.

MetService meteorologist Brian Mercer said Tongariro National Park received 30 to 50 mm or rain last night.

"They still get 3 to 5 mm per hour and that is expected to continue throughout the day and decrease by noon."

These thunderstorms would be accompanied by local heavy rain of 10-20 mm / h and small hail.

The thunderstorms can be squally across Northland, Auckland, Waikato and Waitomo with gusts of 80 to 100 km / h.

A heavy rain watch is in place for Taranaki and the King Country, including the Tongariro National Park until 9 a.m. on Thursday.

Snowfall warnings were also in place for the Desert Rd, State Highway 1, Lewis Pass, SH7 and Milford Rd, SH94, until 11 am Thursday.

This morning on the North Island the desert Rd was at freezing temperature with intake of 0C, while Taupō was at 4.5C.

On the South Island, Pūkaki -3.2C, Christchurch Airport registered -1.3C while Alexandra in Central Otago was a kilt -1.1C.
