Swells are expected to range from 4-6m over the weekend with wind gusts of up to 100k, Ms Murray said.
Snow showers will continue throughout the Gisbourne and Hawke's Bay ranges today with the snow level expected to lift to 700m.
The threat of heavy snow has now been lifted with just 1-2cm of snow expected to settle on the road tonight.
Ms Murray warned those travelling to keep an eye on the forecast as melted snow may form black ice on the road in the evening and early morning.
Conditions are not expected to ease until Sunday, with a warmer brighter forecast predicted for early this week.
MetService will review the current severe weather watch tonight.
