MetService continues to issue Severe Weather Watches and Warnings on the tempestuous westerly flow across New Zealand.

MetService Weather Ambassador Bob McDavitt said, “A brace of thundery squalls moved over the country during the weekend, and further bouts of severe weather are likely  across much of New Zealand over the next few days.”

On Tuesday, northwesterly winds are likely to peak again over central regions, and rain mixed with sleet and hail is expected to affect mainly western parts of the South Island.  Showers in Southland and Otago may bring snow to near sea level for a time.

McDavitt added, “Anyone travelling along the western coastal highways of both islands should be wary of large waves which could affect driving.  The air pressure is so low that the sea level is higher than normal, by as much as 60cm in Foveaux Strait, and there are heavy swells in the Tasman Sea.”

“Late in the week, the wind flow is expected to gradually turn more southerly.  This may bring southern districts another period of snow to near sea level, along with severe gales.”

At the end of this week there is likely to be more road traffic than normal as school holidays start. So before you travel, remember to check the latest weather warnings at, or for those with mobile browsers,
