COUNCIL staff are on standby to sure up flood defences in the Rhyl area should they be needed.
Forecasters have predicted that winds will be off shore reducing the possible impact of the strong winds and high tides.
Natural Resources Wales has said it is keeping a close eye on the North Wales coast from Kinmel Bay to the Dee.
Flood alerts have been issued for high tides across the coastline from 11.45pm on Thursday running into Saturday.
Natural Resources Wales is urging residents along the coast to be prepared as high tides combined with strong winds could lead to coastal flooding.
Natural Resources Wales said it is possible that the highest level Severe Flood Warnings will be issued from Kinmel Bay to the Dee estuary and possibly other areas as high tides approach.
A spokesman for Denbighshire Council said: “In light of the amber warning for possible coastal flooding at tomorrow's (Friday's) high tide at 11am, we would encourage people to keep an eye on the weather forecasts and flood warnings from Natural Resources Wales.
“While we don't want to worry people unnecessarily, we can reassure residents that we are liaising regularly with forecasters and colleagues at Natural Resources Wales.
“The wind is predicted to be off shore rather than on shore this time, so that will help to reduce the impact.
“We have staff on standby ready to shore up sea defences as necessary.”
A Natural Resources Wales spokesperson said: “Although last month’s tides, which caused flooding in many parts of North Wales, were higher in North Wales, this is expected to be the highest tide to hit the whole Welsh coast since 1997.
“Most of the Welsh coastline is likely to experience stormy conditions, and the effects are likely to be worst with the high tides from Thursday evening through to Saturday, with tidal surges and large waves potentially causing localised flooding.
“This is likely to lead to a large number of coastal Flood Warnings and further Flood Alerts being issued across the Welsh coastline.
“As the Met Office forecasts gale force winds, we are monitoring sea levels and weather conditions and will issue flood warnings to registered properties in those areas at risk.”
Motorists have been advised not to drive too close to the coast during high tide.
People are advised to stay clear of promenades and should not stand too close to the sea front due to the risk of large waves or debris.
Emergency response workers will be at key sites checking that coastal defences are in good working order and making sure any drainage grids and screens are clear, to reduce the risk to people and their homes.
Incident rooms are being opened across Wales in preparation.
Officers are also working closely with councils and emergency services to make sure that areas are prepared.
The spokesperson added: “Flood water can be extremely dangerous, and people should not attempt to walk or drive through it unless instructed by the emergency services.”
