CauseThere was a clash of airmasses, with warm air from the depression meeting a surge of cold air to the south. Widespread thunderstorms were occurring within the warm airmass, suggesting that air was already unusually unstable. Warm air became trapped in Hawke's Bay, then became undercut by a cold southerly, leading to violent convection.

Physical CharacteristicAn area, extended from Napier in south to Waikare River in north, received over 250 mm (25.0 cm) of rainfall.

Physical CharacteristicAt one locality, 5 in (12.7 cm) of rain was reported to have fallen in one hour. This exceeds the official all-time New Zealand record of 109 mm in one hour which was recorded at Leigh, North Auckland on 30th May 2001.
