Firefighters are assisting with flooding in Chingford. At its peak, the flood water was 600 millimetres deep on Lower Hall Lane, but levels are subsiding. The water has not affected any homes, but crews have laid sandbags around a local electrical station as a precaution.
Four fire engines, two fire rescue units and 36 fire fighters and officers are at the scene.
