Low pressure sitting off of the western coast of the South Island continues to bring wet weather across the area.

MetService meteorologist John Law says not only is the western side of the island being hammered with rain but this is also spreading to the eastern side.

“We have already seen about 140mm of rain across the top of that western area and we are expecting to see more of that as we go through the rest of today.

“The low pressure is very slow moving and because of that it continues to feed in towards Buller and it wraps around Canterbury.

“We now have a weather watch extending into Canterbury.”

A severe weather warning issued by MetService at 2pm today indicates expected outbreaks of heavy rain in Westland and Buller, also Canterbury High Country within 10km east of the Main Divide until Friday.

“A complex trough of low pressure affects the South Island through to early Saturday. 

“This system will continue to bring rain to central and northern parts of the South Island, with outbreaks of heavy rain in Westland and Buller and parts of the Canterbury High Country near the Main Divide.

“The heaviest rain should fall between Seddonville and Haast until Friday morning, with possible localised downpours and a heavy rain Warning is in force.       

“People in these areas are advised to stay up to date with the latest forecasts and warnings.”

WeatherWatch.co.nz also reports that heavy rain yesterday, overnight and this morning has led to flooding in Greymouth.

“Despite news of droughts being made official in more places today the heavy rain is too much of a good thing with flooding occuring in the past hour or so.

“Over 100mm of rain is possible from this event,” says WeatherWatch.co.nz.

In September last year WeatherWatch.co.nz exclusively said that the pattern for the summer ahead lead weight to a high chance of droughts being announced while at the same time pockets of flooding too.
