Two flood warnings are in place and number of flood alerts following heavy rain in parts of Wales.
It comes after areas of north Wales have been hit by power cuts, including one triggered by high winds snapping an electricity pole.
There had been warnings of heavy rain and strong winds gusting up to 70mph (113km/h).
Part of Wrexham has been affected by a power cut on Wednesday, SP Energy Network has said.
Engineers are on site to investigate.
Power cuts had previously affected "a large number of properties in a widespread area" in the Caernarfon postcode area on Tuesday.
The flood warnings are for the River Rhyd Hir at Riverside Terrace in Pwllheli, Gwynedd, and the Lower Dee Valley from Llangollen to Trevalyn Meadows.
Police reported the A499 between Pwllheli and Llanbedrog was impassable due to flood water and advised drivers to avoid the area.
Flood alerts also cover north and south west Wales.
A Met Office yellow heavy rain warning covering a large area of north Wales is due to end at 18:00 GMT on Wednesday.
An earlier wind warning had covered the counties of Conwy, Denbighshire, Flintshire, Gwynedd and Anglesey.
BBC Wales weather presenter Derek Brockway said the strongest winds were in Capel Curig, Conwy (76mph/ 122km/h), Aberdaron, Gwynedd (63mph/ 101km/h) and RAF Valley, Anglesey (62mph/ 99.7km/h).
Houses in the Dinorwic and Llanberis areas, along with those in Caernarfon, Gwynedd postcode areas, had been left without power on Tuesday, SP Energy Networks said.
There was also an emergency shutdown for safety in Conwy because of a snapped electricity pole.
A third area affected was Denbigh, Denbighshire, in Prion and Peniel.
The Met Office had previously warned of "strong south to south-westerly winds" between 50 and 60mph at times, with potential for even stronger gusts.
The warning for "heavy and persistent" rain covers Conwy, Anglesey, Gwynedd and Powys, with "flooding of a few homes and businesses likely", as well as some travel disruption.
