MetService has issued a Severe Weather Warning for Westland and Fiordland and put the Tasman District on a Severe Weather Watch for a period of heavy rain during the passage of a low-pressure system across the South Island on Thursday and Friday.

“Current projections suggest that the low-pressure system is going to weaken as it approaches the South Island,” commented MetService Weather Ambassador, Bob McDavitt.  “This should mean less rain accompanying the system compared to recent events.”

“There may still be sufficient amounts of rain reaching the Clutha catchment during Thursday so that people near the already high Southern Lakes and rivers should keep a close watch for further rises in water levels.”

As this low moves away on Friday, a cool southerly wind change is expected to spread across the eastern South Island and reach Cook Strait by nightfall.
