HEAVY rain is expected across Wales overnight tonight (Friday) into Saturday morning.
Thunderstorms will bring localised torrential downpours during Saturday morning and only the extreme West and North West of Wales are likely to escape the heaviest bursts.
Flooding may occur and there is the risk that smaller, faster responding urban rivers will rise.
Anyone traveling tomorrow is advised to take care and allow extra time for their journey as driving conditions may be hazardous.
Natural Resources Wales is advising people to keep an eye on weather reports for any signs of disruption in their area.
Flood alerts are updated every 15 minutes on the Natural Resources Wales website.
