Flooding possible. Be prepared.
Groundwater is high, very close to the surface, but slowly falling at Ladies Mile borehole. Despite Sunday's rain. In Patcham village, groundwater may continue to steadily rise all week. Widespread rain is forecast Wednesday. There is uncertainty in rainfall amounts. Between 10mm and 40mm. If the smaller amount of rain occurs, groundwater levels at Ladies Mile could continue to fall. If the maximum rain occurs, groundwater levels at Ladies Mile will likely rise again. Either way, groundwater flood impacts will continue all week. Probably until March. A small amount of water could appear in a few basements. Previous events suggest impacts may initially affect Old London Road, Patcham and Peacock Lane, Withdean. If the maximum forecast rain occurs on Wednesday, groundwater could rise until 24/02/2026, perhaps longer, and a small amount of water may appear on roads. The weather outlook remains unsettled into March, although perhaps with rain less often. Ensure pumps work. We are liaising with Brighton and Hove City Council. We will update this message by 18:00 20/02/2026.
