Severe Thunderstorm Warnings
Severe Thunderstorm Watch
Area: Northland, Auckland, Great Barrier Island, Coromandel Peninsula, Waikato, Waitomo, Taumarunui, Taranaki
Period: 6hrs from 10am – 4pm Thu, 2 Jun
Forecast: An active front is moving across the North Island today, bringing squally thunderstorms with heavy rain and hail, and a chance of a small tornado. There is a moderate risk of these thunderstorms becoming SEVERE, producing localised downpours with intensities of 25 to 35 mm/h (most likely about Waikato and Waitomo), large hail, damaging wind gusts in excess of 110 km/h, and the chance of a localised damaging tornado near the west coast this morning.
Rainfall of this intensity can cause surface and/or flash flooding, especially about low-lying areas such as streams, rivers or narrow valleys, and may also lead to slips. Driving conditions will also be hazardous with surface flooding and poor visibility in heavy rain.
Large hail can cause significant damage to crops, orchards, vines, glasshouses and vehicles, as well as make driving conditions hazardous.
Wind gusts of this strength, and damaging tornadoes can cause structural damage, including trees and power lines, and may also make driving hazardous.
Issued: 9:55am Thu, 2 Jun
