It's expected the weather will improve for Christmas Day in Whanganui after a week of stormy conditions.
MetService meteorologist Andrew James said southerly winds are expected for Whanganui and the central New Zealand area on December 25.
"Those do bring in a bit of cloud but things should remain dry with any shower activity occurring farther inland. There is a possibility that it could affect Whanganui city but it's too early to be totally definitive about that."
James said similar conditions are expected for Boxing Day.
A temperature of 22C has been forecast for Christmas Day and Boxing Day.
