Dorset Council, the Environment Agency, and emergency services are advising residents and road users that Portland Beach Road and the Causeway may need to close again this morning (Saturday 24 January) due to a high likelihood of flooding between 09:15 and 12:30. 

The road was previously closed between 22:00 and 00:45 last night after waves overtopped and floodwater penetrated the beach, making the route unsafe. The road was reopened shortly after 00:45. 

Multi-agency teams remain on site monitoring weather conditions, sea state, and local water levels. Digital signage continues to warn drivers of the risk of closure. If the road must be closed again, it will only reopen once it is safe and clear of debris.  

Ongoing severe weather conditions 

The same hazardous conditions associated with Storm Ingrid remain in place, including high spring tide and strong winds. 

This combination continues to increase the risk of waves overtopping the beach and water penetrating the beach and flooding the Causeway, potentially requiring further closure in the interest of public safety. 

There is also an ongoing risk of waves overtopping flood defences around Chiswell, leading to possible flooding and shingle being thrown onto the road and nearby properties. Areas most at risk include A354 Chiswell, Brandy Row, Pebble Lane, Victoria Square up to the junction with Queens Road, the car parks along the A354 and the yard along Lerret Road. Residents in these areas should remain prepared for flooding and debris. 

What you can do 

  • Avoid travel on coastal roads, cliffs, and shorelines across Dorset during this morning’s weather conditions. 
  • The Portland Beach Road and Causeway may be closed between 9.15am and around 12:30pm so please make alterative travel plans and avoid travel on roads leading up to the Portland Beach Road and Causeway. 
  • Residents in affected areas should follow Environment Agency advice, including: 
  • act on your personal flood plan if you have one 
  • follow the guidance in what to do before or during a flood.

Support for vulnerable residents 

Dorset Council is continuing to check on residents known to Adult Social Care and is coordinating with care providers to ensure support can be delivered where needed, even if the Causeway is closed.
