A short spell of heavy rain and gusty winds may cause some travel disruption.
Another spell of wet, windy weather will arrive across southern parts of Wales and southwestern parts of England in the early hours of Wednesday.
For many this will be fairly normal (if unpleasant) autumn conditions but for a few there could be a short interlude with torrential rain and very gusty winds.
The warning will be in force from 3am until 8am on Wednesday.
