Four people have been rescued after two cars became stuck in flood water as the clean-up continues following Saturday's downpour and strong winds.
Emergency crews helped the occupants to safety after the incident at Bangor-on-Dee, Wrexham, on Sunday at 08:05 GMT.
Capel Curig saw half a month's worth of rain - 136.6mm - in 24 hours, according to Natural Resources Wales (NRW) and five flood warnings remain in place.
Homes were flooded at Betws-y-Coed and Llanrwst in Conwy county.
Rivers levels across Wales are now falling but officials are "continuing to monitor the situation" in Bangor on Dee as it "responds more slowly to the rain".
This is Bangor on Dee Wrexham. It is clearly impassable. There are various signs across North Wales currently advising and urging people not to try and use certain roads following the atrocious weather. Please DO NOT IGNORE these warning signs or try your luck. Thank you. pic.twitter.com/BxQhhAjuVu— North Wales Police (@NWPolice) March 17, 2019
Strong winds also caused disruption to roads, bringing down trees and more than 700 properties in south Wales and Ruthin, Denbighshire, experienced power cuts.
North Wales Fire and Rescue Service said about 40 properties had flooded in Parc yr Eryr, Llanrwst. Three people also had to be rescued from a van stuck in flood water near the town.
Betws-y-Coed resident Tamzyn Lawrence said: "It's a good neighbourhood - everybody comes together in times like this when they're needed."
On Sunday, roads in several parts of Gwynedd and Denbighshire were reopened, including the A5 in Corwen and the A470 in Llanrwst.
Road agencies have also reopened the A487 Dyfi Bridge at Machynlleth in Powys.
However, the B5106 at Trefriw in the Conwy Valley is "just passable" due to flooding.
Train services between Llandudno and Blaenau Ffestiniog on the Conwy Valley line remain suspended.
There were 10 flood warnings at one point but they are reducing with concerns still for the River Dee and River Conwy in north Wales, as well as the River Severn at Welshpool, Powys.
Donna Littlechild, from NRW, said: "We have seen roughly half of the monthly average with 136mm of rain fall in the last 24 hours. This was hitting ground which was already extremely wet and high rivers following Strom Gareth.
"The situation is improving today and we expect to be able to remove most of the flood warnings as the situation improves across most areas.
"We aren't expecting to see much rain over the next 48 hours and river levels are falling."
