The Missing Piece: Philip Sutton

Tragedy has struck the Karori community as the search for Philip Sutton, a man in his 60s and NZ Post employee, reached a somber conclusion.

The Incident: Sutton was swept away early Monday morning when a torrent of floodwater and debris smashed through a studio he was staying at in Karori.

Latest Update: Police confirmed that a body was located just after midday on Wednesday, a "substantial distance" from where his car was found. Inspector Fleur de Bes noted the family has been notified and the search in the challenging semi-rural terrain has been suspended.

Why the Forecast Missed the "Bullseye"

Chris Brandolino, principal scientist at Earth Science New Zealand (formerly NIWA), explained that while a big low-pressure system can be modeled days in advance, small-scale thunderstorms are "very hard to forecast" because they develop with extreme speed over tiny areas.
