MetService has issued Severe Weather Warnings and Watches to cover a period of heavy rain that is expected to affect many western districts especially on Wednesday and Thursday.

“People in western areas should brace for a few days of rain,” commented MetService Weather Ambassador, Bob McDavitt. “This rain band is expected to pause over central South Island for a time, before resuming its northward progress during Thursday and early Friday.”

Accumulated rain amounts are expected to reach around 250 mm over parts of the Southern Alps during Tuesday and Wednesday, and heavy rain is expected to affect western Nelson and the headwaters of Otago and Canterbury rivers.

McDavitt added that people living around Mount Taranaki, the Tararua Ranges, Marlborough Sounds and the Richmond Range have been put on watch and should be ready for the likelihood of heavy rain especially on Thursday.  This Severe Weather Watch may need to be upgraded to a Warning so keep up to date with the latest forecasts and plan accordingly.  Updates are available on, and, for mobiles, on

“Parts of this area are already soggy and even moderate amounts of widespread rain may trigger some slips in hilly areas and surface flooding on some roads.”

“These rain clouds do come with a silver lining,” said McDavitt. “They are likely to be followed by a warm and sunny anticyclone that should linger over much of New Zealand through the weekend and into early  next week. Great for the school holidays.”
