The alert covers the Dartford Creek up to the Thames Barrier in south east London.
This follows on from heavy rainfall in London on Thursday and Friday, with yellow weather warnings issued by Met Office for 26 hours.
Further rain has been forecast in London today (February 11), as another yellow weather warning is in place for parts of south east England, although London is currently not affected.
What areas are affected?
A flood alert has been issued for the Tidal Thames riverside from Dartford Creek and the Mardyke to the Thames Barrier in south east London.
The following areas are covered under this warning:
- New Charlton
- Woolwich
- Plumstead
- Erith
- Belvedere
River levels are expected to be high due to spring tides and a closure of the Thames Barrier.
The Environment Agency has advised that water will be maintained within the downstream network of flood defences including river walls, embankments and flood gates.
However, flooding of low-lying footpaths and open spaces is possible for between one and two hours around high tide.
High tide at the Thames Barrier is currently forecast for 2.30pm today (February 11).
The Environment Agency is monitoring the situation, with incident response staff in the area working to ensure that flood gates are closed.
Members of the public are being advised to avoid floodwater and to check for further updates.
What to do?
Residents in affected areas are being advised to monitor local water levels and weather conditions whilst flood alerts are in place, and to act on their flood plans.
People are also advised to avoid using low lying footpaths or entering areas prone to flooding.
