Whanganui woke to steady rain as an active cold front passed through between 5am and 6am on Tuesday.
There was 5mm of rain between 6pm and 6am, MetService meteorologist Mmathapelo Makgabutlane said. Most of it fell in the last hour.
More showers are predicted for the rest of the day, but they will happen on and off, and they may not be heavy.
At the same time westerly winds will average 45km/h, which is quite strong, and they will gust to 72km/h.
Combined with a top temperature of 16C, it would make for quite a chilly-feeling day, Makgabutlane said.
