Back to business as usual after summer storm
The intense summer storm that brought heavy rain, strong winds and coastal inundation to parts of northern and central
New Zealand from Thursday to early Saturday now lies well to the south of the Chatham Islands and continues to move away
to the southeast today.
“The largest impact of this event was associated with king tides combining with a storm surge and exceptionally strong
onshore winds and swells, creating major inundation along exposed coastal areas. This was most evident in the Firth of
Thames and coastal parts of Coromandel and Bay of Plenty, where some of the worst coastal flooding for many decades
occurred. Parts of Auckland also saw significant coastal inundation during this event, while the south coast of
Wellington was not spared with large waves affecting access to Eastbourne.” explained MetService Meteorologist Andy
Downs.
The strong winds associated with this deep low also caused damage in parts of northern and central New Zealand, with
numerous trees being brought down and power outages reported, especially about parts of Auckland, Coromandel, Bay of
Plenty and Hawkes Bay. Sadly, falling trees struck at least two cars, resulting in one death.
Significant rainfalls were also reported over parts of northern and central New Zealand during this time, which has
helped to alleviate drought conditions in these areas. However, the intensity of the rain, which was enhanced by very
moist air dragged down from the subtropics, also created extensive surface flooding and hazardous driving conditions on
top of exacerbating the significant coastal inundation.
The good news for people clearing up in the worst affected areas, such as the Firth of Thames, Coromandel Peninsula and
western Bay of Plenty is that more benign weather is forecast for them over the coming week. There may still be a few
showers, but these will be very hit and miss with plenty of warm sunshine to help conditions dry out.
Further south, over the lower North Island and parts of the South Island conditions are likely to become increasingly
unsettled next week, especially from Tuesday onwards. Rain is likely in some of these areas, which will be welcome news
to farmers and fire-fighters, but not for tourists and holiday makers. This is also a good time to remind people who may
be heading out into the high country areas to always be prepared for changeable conditions.
