Families and businesses in Cheshunt, Hertfordshire, have been warned to prepare for possible flooding after heavy rain associated with Storm Chandra on 26–27 January 2026. Briefings from the Environment Agency and local authorities said the Small River Lee reached high levels at the Windmill Lane gauge early on 27 January and that a Flood Warning was issued at 04:15 on 27 January; however, the Environment Agency’s public “Check for Flooding” service showed no active flood warnings for Cheshunt as of 7:29pm on 27 January 2026.
Those briefings identified low-lying land near Windmill Lane and Cadmore Lane, and areas around Cheshunt station, as the most at risk. An internal monitoring post at Windmill Lane was recording river levels of 1.370m at 6:45pm on 27 January (RiverLevels.uk), and briefings warned that overtopping and locally high groundwater could affect footpaths and local roads. There is no independent confirmation on the public river-level feed or the EA warning map at 7:29pm that properties were actively flooding.
The Met Office, according to the briefing, said parts of the South East received more than a month’s worth of rain in less than 36 hours, and Hertfordshire County Council warned that the county’s soils are exceptionally saturated and that even small extra rainfall will run straight off into streets and drains. Local authorities are warning residents to move valuables upstairs and to check on vulnerable neighbours.
Commuters are being advised not to drive or walk through floodwater and to expect possible disruption around the A10 corridor and Cheshunt station; officials warned the risk of disruption is likely to remain high until Wednesday morning (28 January 2026).
