Natural Resources Wales (NRW) is asking people to take extra care near the coast this weekend as seasonal high tides could cause dangerous conditions.
High tides are likely to affect most areas of the coastline, but the stretch along South Wales - from the Gower through to the Wye Estuary - is likely to be most affected.
These areas could see localised flooding of coastal roads, and the potential for spray to overtop promenades, piers.
Spring tides are expected to peak Saturday morning and evening, before reducing from Sunday onwards. However, the weather forecast for Monday remains unsettled, and an increase in wind speed could cause further hazardous conditions.
Flood Warnings are already in place for Crofty on the Gower, and for the Wye Estuary at Tintern and Chepstow, as well as a number of the less serious Flood Alerts across the country.
Forecasters from NRW continue to monitor tidal and weather conditions closely and will issue further warnings if necessary over the weekend.
Operational staff are also on site at susceptible areas to watch out for any potential impacts.
People are advised to keep up to date with local news and weather reports, and check for the latest Flood Alerts or Warnings in their areas by phoning Floodline on 0345 988 1188 or visiting this page.
