Elevated areas of Hawke's Bay could wake to snow on Friday morning, as a cold snap that could cause havoc for drivers brushes through.
MetService meteorologist Kyle Lee said a southerly change sweeping over the region on Thursday night will turn already heavy rain in the region into snow on some of the ranges around Hawke's Bay.
A road warning was in place for State Highway 5, the Napier-Taupo road, with rain turning to snow above 700m overnight.
Between 2cm and 4cm of snow may settle near the summit of the road, Lee said.
"There is a front that is bringing with it plenty of rain but a southerly wind moving in overnight will undertake most of that rainfall," Lee said.
