Whanganui and other parts of the region had a wet and windy Sunday after a northwesterly front arrived on Saturday night bringing rain and strong winds.
Metservice meteorologist Mmathapelo Makgabutlane said winds were gusting up to 70km/h at Whanganui Airport during Saturday night.
"That is quite strong but it was much stronger in Waiouru where gusts of 102km/h were recorded early on Sunday morning," she said.
