This is an archived message. The status has changed more recently.
17mm of rain has been recorded overnight Sunday into Monday. A lot less than could have been possible. A small river response has been observed, but it is not thought flooding from the river has occurred. River levels are now falling. There is a possibility of between 5 – 15mm of rain forecast for the rest of Monday, but this is not expected to cause significant river rise. Minor flood impacts could still be possible if an intense shower affects Polegate, but the likelihood is low. Please remain prepared for minor flood impacts. If you see a blockage affecting the river, please call our incident hotline on 0800 80 70 60. We regularly clear debris from grilles at Gosford Way, to help keep the river flowing freely and reduce flood risk. We will re-issue this Flood Alert if property flooding is thought possible.
