He said a front was crossing the Whanganui area on Wednesday which heralded a period of heavier showers.
“Heavier showers will start to come through on Wednesday, and the rain could be more persistent.
“There is the possibility that there could be some small hail.”
The wind was also expected to pick up on Wednesday.
“We’ll see those westerly winds getting fairly strong.
“But the main message is that some of those showers on Wednesday could be heavy, so be prepared.”
Miller said at this stage, the showers and wind were expected to drop off in the second half of the week from Wednesday through until Friday.
“The end of the working week will bring more settled weather.”
