Flood Warning issued on 9 Jul 2021 20:48
Heavy rain is currently falling in the Upper Witham catchment and will continue throughout the evening of Friday 9th July. This is causing the Mow Beck and Barrowby Stream to rise and is forecast to continue to rise through the evening. The rising river levels have already caused flooding of low lying land and roads in Grantham, and due to the deteriorating weather conditions we now expect properties in Grantham to be affected from the evening on Friday 9th July onwards. Low lying properties near the Mow Beck and Barrowby Stream are most at risk. Remain safe and be aware of your local surroundings. Please avoid contact with flood water. Our staff are out in the area to check the flood defences, clear blockages, and assist the emergency services and council. We will be closely monitoring the situation and this message will be updated as the situation changes.
