Flooding possible. Be prepared.
Groundwater is high, close to the surface, but slowly falling at Ladies Mile borehole. A small amount of water could still be appearing in a few basements, although likely to be infrequently now. Previous events suggest impacts may initially affect Old London Road, Patcham and Peacock Lane, Withdean. Only small amounts of rain are forecast over the five days to 06/03/2026, and groundwater at Ladies Mile borehole will continue to slowly fall over the coming week. There is a suggestion that high pressure, settled conditions, and only small amounts of rain could continue in the south east of England through the first half of March 2026. Which would allow groundwater to fall for longer. However, with groundwater being as high as it is, groundwater flood impacts could still continue through the first week of March. Ensure pumps work. We are liaising with Brighton and Hove City Council. We will update this message by 18:00 06/03/2026.
