Major storm about to slam into South Island, New Zealand

Major storm about to slam into South Island, New Zealand

What's left of former Tropical Cyclone "Fehi" is now approaching New Zealand as a major storm and is expected to hit South Island and lower parts of North Island with significant heavy rain and strong winds as it crosses the region over the next 36 hours.

While Fehi has lost most of its tropical characteristics this is still a very dangerous storm expected to bring very heavy rain and possibly damaging winds to much of the South Island and parts of the lower North Island from late Wednesday to early Friday morning (local time).

"The heaviest rain is expected in the South Island (apart from Canterbury Plains and Kaikoura Coast), especially in Westland and Fiordland where 200 to 400 mm [7.8 - 15.7 inches] of rain could accumulate from tonight to early Friday. Heavy rain is also expected for Mt Taranaki and Tararua Range," New Zealand's Met Service warns, adding that a Heavy Rain Warning is in force for these areas. 

Rainfall of this intensity can cause flash flooding, especially about low-lying areas such as streams, rivers or narrow valleys, and may also lead to slips. Driving conditions will also be hazardous with surface flooding and poor visibility in heavy rain.

Gale force winds are expected for southern and central New Zealand, initially from the north, but turning northwest then southwest later.

The strongest winds are likely to be in Westland, Buller, Canterbury High Country, Nelson, Marlborough, Wellington and southern Taranaki, and a Strong Wind Warning is in force for these areas.

People are strongly urged to keep up to date with the latest forecasts and warnings in case other areas will be added to the Warning.

In addition, please note that the combination of strong winds, heavy swells and high tides could cause coastal inundation about the west coast of South Island and also Nelson during Thursday.

Quote: "A big storm is going to slam into the South Island, New Zealand."
If New Zealand wants to organize an influx of the world elite and business elite into the country, it must hire an operating ecologist.
His duties will include the elimination of the following natural situations:
First. Quotation: "Hurricanes and storms form due to pressure and temperature changes". Reduce the destructive power of storms and hurricanes to minimum values.
The second. New Zealand, and the territory for hundreds of kilometers around it - is a heap of mountain formations emerging from the water. The law of physics: "All crystalline bodies with heating (warming), expand." Expansion leads to catastrophic stresses at the joints. Joints are destroyed - and there is an underwater earthquake and a tsunami. This is what happened in Indonesia, when 230,000 people died. The official version of the scientists: "Joints of two lithospheric plates could not withstand the loads, collapsed - and one plate dived under the other."
Third. Bunkers should be self sufficient: they are provided with high-quality air, water, and food for a long time.
If New Zealand requires environmentalists who are able to fully ensure the security of the elite, call - I will come.

Цитата: «Большой шторм собирается хлопнуть в Южный остров, Новая Зеландия».
Если Новая Зеландия хочет организовать приток в страну мировой элиты и бизнес элиты, она должна нанять действующего эколога.
В его обязанности войдёт устранение следующих природных ситуаций:
Первое. Цитата: «За счёт перепадов давлений и температур образуются ураганы и штормы». Снизить Разрушающую мощность штормов и ураганов до минимальных значений.
Второе. Новая Зеландия, и территория на сотни километров вокруг неё – это нагромождение вышедших из воды горных образований. Закон физики: «Все кристаллические тела при нагревании (потеплении), расширяются». Расширение приводит к катастрофическим напряжениям на стыках. Стыки разрушаются – и происходит подводное землетрясение и цунами. Именно такое явления произошло в Индонезии, когда погибло 230 тысяч человек. Официальная версия учёных: «Стыки двух литосферных плит не выдержали нагрузок, разрушились – и одна плита нырнула под другую».
Третье. Бункеры должны быть само достаточны: обеспечены качественным воздухом, водой, и продуктами питания на длительные сроки.
Если Новой Зеландии требуются экологи, способные полностью обеспечить безопасность элиты, зовите – я приеду.
