Frost fighters stand by (NZ)

Plummeting temperatures meant activated frost alarms and helicopters placed on standby around Marlborough overnight on Wednesday. Climate Consulting climatologist Stu Powell said a slight frost would have been felt in the Wairau Valley and at Fairhall, which recorded the lowest temperature in the region, -0.2degC. He expected many vineyards would be wanting frost alerts until at least the first week of May this year, due to the late grape harvest, reports The Marlborough Express.
