Whanganui is not included in MetService's severe thunderstorm watch for the early part of this week although the region is still in for some bad weather.
"Thunderstorms are likely to affect Whanganui on Sunday night and Monday but they are not in the severe category," MetService meteorologist Stephen Glassey said.
"There is a strong wind warning however and that will be in place from 6pm on Sunday until 11pm on Monday. The big trough moving over the whole country is bringing squally showers and strong, gusty northwesterlies to most places."
Glassey said the northerly flow means that temperatures won't be too low and a high of 14C is forecast for Monday with an overnight low of 9C.
"There is likely to be plenty of showers throughout the day and some might be heavy," Glassey said.
