If heavy rain does affect the area in the next couple of weeks, some ponding of water will affect gardens in Over Wallop, and land flooding could affect property in Broughton. Cellar flooding in Pitton and West Tytherley could occur towards the end of February. We continue to monitor the forecast. Please ensure that any pumps used to reduce water levels are working.
