Flood Alert issued on 11 Jul 2017 21:19
We have seen widespread rain across much of London this afternoon, Tuesday 11 July. As we move through this evening and into the early hours of tomorrow morning (Wednesday 12 July) there is a risk of further heavy bursts of rain.
We expect the river Ingrebourne to rise in response to this rainfall in the early hours of Wednesday. There is the potential for flooding to affect low lying land and roads close to the river in the Hornchurch and Harold Park areas. No flooding to properties is anticipated.
The river should return to normal levels by lunchtime tomorrow. Take care near the areas of concern and monitor your local weather conditions.
We are constantly monitoring river levels and will update this message on Wednesday morning or earlier if the situation changes.
