South Island

Multi HazardMulti Hazard at South Island
Duration:   4  days - From the 11th to the 14th of December.
Comments:

CauseA principal cause was the stalling of a front as it moved over the southern South Island. On the evening of the 11th, an active cold front crossed Fiordland and Southland, preceded by a long fetch of northerlies from the subtropics. During the 12th, this remained stationary, blocked by large high to east, while a weak southerly spread into eastern districts. Overrunning of moist warm air produced high rainfalls in eastern areas on this day. Convection also played a major role and helped heavy rain spill over well east of the divide. Snow melt helped turn this into a major flood event.

CommentIn the South Island, heavy rainfall and associated snow-melt resulted in abnormally high lake levels.

ImpactA number of trampers were trapped in the Arthur's Pass, Mouth Aspiring and South Westland areas.
