A new band of wind and rain is set to bring further disruption to parts of Wales, following Storm Ciara.
Forecasters have said Storm Dennis will move in from 12:00 GMT on Saturday with the wind easing by night, but rain continuing until Sunday lunchtime.
Parts of the country were hit by 93mph (150km/h) last Sunday, with 122.6mm (4.8in) of rainfall in places.
One side of the M48 Severn Bridge between Wales and England near Chepstow has reopened following a lorry crash as strong winds continued on Monday.
The westbound carriageway is open again, but the lorry will remain in place on the eastbound side until strong winds subside.
Other problems in the aftermath of Storm Ciara included cars becoming trapped in Gwynedd following heavy snow.
The A547 between Abergele and Llanddulas in Conwy is closed in both directions because of flooding.
Trains have also been cancelled between Llandudno Junction and Blaenau Ffestiniog due to severe flooding and damage on the Conwy Valley line.
Services on the Cambrian Line between Machynlleth and Aberystwyth and Machynlleth and Pwllheli are blocked and buses will replace trains.
Network Rail and Transport for Wales have both urged people to check before they travel, with a number of other lines also affected.
Stena Line ferries between Fishguard to Rosslare were cancelled on Monday, but began operating again on Tuesday.
Four flood warnings were in place around north Wales on Tuesday lunchtime, which means flooding is expected and immediate action required.
The warnings are at Kinmel Bay promenade in Conwy county, the Lower Dee valley near Llangollen, Llanddulas, and Rhyl splash point.
Environment Minister Lesley Griffiths said flood defences had worked in many parts of Wales and early indications had shown river levels were higher than when there was widespread flooding in St Asaph and Ruthin in previous years.
She added: “It is vital to investigate the flooding that did occur and learn lessons to further protect our communities.
“It is now for local authorities to investigate and report their findings and recommendations, in collaboration with Natural Resources Wales and other stakeholders.”
