Reporton mid-February storm in Wellington and Miramar's heavy rainfall

This report summarises the meteorology and hydrology of the 15 - 16 February 2004 storm event that affected the Wellington region. The report gives an overview of the synoptic weather patterns, quantifies the rainfall and river flows, and provides a frequency analysis of the event. The hydrological data used is from Greater Wellington Regional Council's environmental monitoring network, supplemented with data from NIWA, the MetService and private landowners.

During the storm event slips and flooding caused damage in many parts of the region, in particular in southern Wairarapa, Wainuiomata, the Hutt Valley and Eastbourne. However, this report is a hydrological analysis and does not describe the effect of flood protection measures, the damage that occurred or the civil defence response during the event.

Throughout February 2004 there were several storms that affected parts of the Wellington region. This report covers the largest event that had the most significant region-wide impacts. Hydrologic data for the other events can be obtained by contacting Greater Wellington.
