Engineers are still working to restore power to around 100 homes in south and west Wales today.
It follows last night's strong winds of up to 80mph which left 25,000 homes without power.
Winds brought down trees in Cardiff, Llanelli and Bridgend and caused travel disruption for many.
The M4 was blocked yesterday afternoon after a caravan overturned. The M48 Severn Bridge was also closed.
Natural Resources Wales are monitoring the situation as wind and waves could lead to further alerts being issued.
