Bands of heavy rain and strong gusts of winds are expected to sweep across the West on Wednesday.
The morning will see the worst of the wet weather, before conditions turn brighter in the afternoon.
The temperatures are also expected to turn slightly colder, dropping to around 8 or 9 degrees Celsius.
Looking ahead to later in the week, Thursday will be a fairly sunny and cold day - and it will stay chilly right into the weekend.
However, Friday and Saturday both look like cloudier days, with outbreaks of rain moving through on Friday.
