Cheshunt, Hertfordshire, is forecast to face roughly 48 hours of persistent heavy rain and gusty winds that are expected to cause surface-water flooding and travel disruption through Friday evening, 6 February 2026. Meteorological models put the probability of continuous rainfall at about 95%.
The Met Office has issued regional weather warnings covering parts of London and the South East; however, the Met Office’s dedicated Cheshunt warnings page listed no warnings in force for Cheshunt as of 5 February 2026. Gusts of around 30 mph are expected in the area.
The Environment Agency is monitoring river and drainage levels, including the Small River Lee at Windmill Lane. As of 9:57am on 5 February 2026 there were no flood warnings or alerts for the Cheshunt/Waltham Cross area, but authorities warn that saturated ground and persistent rain can overwhelm local drainage and lead to ponding on streets and in low-lying gardens.
Police are urging drivers to slow down and leave extra space between vehicles to reduce the risk of aquaplaning and collisions in spray. National Highways is monitoring M25 Junction 25 (the A10 interchange), a known hotspot for flooding and lane closures during heavy storms.
Train services and local commutes may also be affected; residents should check updates from train operators (Greater Anglia / Network Rail), National Highways and local news before travelling. The period of heaviest rain is expected to ease by Friday evening, with conditions improving into Friday night.
