Lightning struck a house in Caerphilly county on Friday afternoon A Natural Resources Wales (NRW) spokesperson said: "Although the tides peaked this morning across large areas of Wales, this evening's tides remain very high and predictions show that in Cardigan Bay they may be higher than this morning's levels.
"This could lead to further overtopping of sea defences and flooding to roads and properties close to the seafront at Aberystwyth and Borth."
The day's first tide - combined with high winds and rain - left a trail of chaos with emergency services carrying out rescues at Cardigan and Gwynedd.
First Minister Carwyn Jones tweeted: "My thoughts are with those affected by the bad weather. Please follow advice of the emergency services."
In communities along the whole of Wales' coastline dozens of roads were closed and the rail network was also badly affected.

In Flintshire, rest centres were set up for people who were advised to leave their homes at Greenfield and Talacre in anticipation of more floods that hit neighbouring Rhyl in early December.
However, the Flintshire coast escaped serious incidents in the lunchtime high tide.
But Chief Supt Jeremy Vaughan of North Wales Police who led the response, said: "On this occasion whilst it was unfortunate that some properties were flooded, the impact was less severe than anticipated, this could have been very much worse."

Earlier, as the high tide hit south Wales, police were called to move people from Burry Port pier in Carmarthenshire.
Ron Cant from Carmarthenshire council said some people were ignoring the dangers posed by the high winds and tides and the police had been called.
The council had crews working through the night helping out at flooding incidents. More staff are now being called in from annual leave to help if needed as the bad weather is forecast for the weekend.

Aberaeron harbour in Ceredigion before high tide on Friday morning The high tide - thought to be the worst in 17 years - started to hit the coast of Pembrokeshire after 07:00 GMT and reached north Wales after midday.
Pembrokeshire council has already advised householders and business owners whose properties are at risk of flooding to prepare for continued high tides over the weekend by stocking up on sandbags and tarpaulins at local builders' merchants.
Police warned people to stay away from some wave-lashed seafronts.
Some homes in Newport were evacuated overnight as a precaution.
Homes on the Lighthouse Park Estate in Wentlooge Levels, Newport and in the area north of Crindau, Pill were affected.
Joanne Sherwood, from Natural Resources Wales (NRW), said: "This is the some of the highest tides since 1997, and on top of that it's very windy so that's causing about a one metre surge on top of the tide.
"We think this is serious and we've had our teams out and about checking defences making sure things are in good working order," she told BBC Radio Wales.
Meteorological officer Charlie Powell told Radio Wales: "We've already seen gusts of up to 70mph across some exposed western parts of Wales and it's the wind that's going to be the crux of this next batch of severe weather.
"We can expect to see tides peaking as we go from south to north and as these strong winds coincide with those high tides and push that water it gives really high waves and that just increases the risk of coastal flooding.
"It's relatively rare to see all these things combining at exactly the same time and it's exactly why these risks are so high this time."
He added that the hills and mountains of Wales will be worst hit by the winds.
