A Met Office weather warning for heavy rain is set to be in place for large parts of south and west Wales with up to 50mm of rain expected in some areas. The yellow alert was updated to start at midnight on Friday (November 17) to 10am on Saturday (November 18).
The forecasting agency says that some of the rain "especially in southwestern parts of the UK" will be "heavy at times" and follows weeks of above-average rainfall in the areas.
Weather maps show heavy rain falling in south parts of the country through most of the night on Friday and during the early hours of Saturday morning.
