Forecast: Humid and unstable conditions are expected to bring thunderstorms to many areas of the North Island during today, producing localised heavy rain and hail. In the Bay of Plenty, including Rotorua, Waikato and the Coromandel Peninsula, there is a moderate risk some of the thunderstorms could become SEVERE. These SEVERE thunderstorms could bring large hail greater than 20mm in diameter, strong winds gusting greater than 110 km/h, and even the risk of a small tornado. Large hail can cause significant damage to crops, orchards, vines, glasshouses and vehicles, as well as make driving conditions hazardous. Wind gusts greater than 110 km/h in strength can cause some structural damage, including trees and power lines, and may make driving hazardous. If any tornadoes occur, they will only affect very localised areas.
