Natural Resources Wales has issued a severe flood warning for the River Ritec at Tenby, affecting Kiln Park caravan site, the B4318 at Clicketts Lane, Gumfreston Road and Trefloyne Lane.
The level of the river Ritec has been rising steadily since 8am on Tuesday January 2, the warning states.
Flooding has become very extensive within Kiln Park and there is the risk of severe disruption to the community, with significant risk to life.
Kiln Park owners and visitors are urged to comply with directions from the emergency services and staff at the holiday park.
Be aware that some roads in this area may already be closed or affected by floodwater.
There have been reports of raw sewage in the floodwater and therefore precautions should be taken to avoid contact with the water.
Due to the restriction of the tidal outfall, water levels will rise over the period of each subsequent high tide. The next peak is expected to occur at 1am tonight (Wednesday, January 3).
The continued trend of an increasing river level is anticipated. Access to and from the Kiln Park caravan site may be affected. Further disruption in the area is possible. You can monitor the situation in your area by using the River Levels Online Service on the Natural Resources Wales website.
