Get flood warnings by phone, text or email
Groundwater is high, very close to the surface, but now slowly falling. Despite Sunday's rain. More rain is now forecast for Wednesday. There is uncertainty in rainfall amounts. Between 10mm and 40mm. If the smaller amount of rain occurs, groundwater levels could continue to fall. If the maximum rain occurs, groundwater levels will likely rise again. Either way, groundwater flood impacts will continue all week. Probably until March. Springs will appear, water will be in fields, small amounts of water will flow down roads, groundwater will affect the ability of the sewage network to operate in East Dean, Charlton, Singleton and West Dean, and may appear in a small number of basements. If the maximum forecast rain occurs on Wednesday, groundwater could rise until 24/02/2026. Perhaps longer. The weather outlook remains unsettled into March, although perhaps with rain less often. Take care on roads that flood (Chilgrove, West Dean, Singleton, East Dean). Ensure pumps work. We will update this message by 18:00 20/02/2026.
