A flash flood risk outlook is in effect for Lucknow on Monday, Sept 28, 2026, with river flow at 3.3 times the normal level. The figure comes from a model-based outlook by LatestLY using river-discharge and rainfall forecast data, and is not an official government alert.

Residents have been advised to avoid low-lying areas and to expect waterlogging and travel delays. Lucknow recorded 50.6 mm of rain on Friday between 8:30 am and 5:30 pm, and the airport weather station logged 86.6 mm in 12 hours.

The IMD issued a ‘pink alert’ for several UP districts on Sept 26, warning of heavy to very heavy rain and flagging flash flood risk. Chief Minister Yogi Adityanath ordered district magistrates to stay vigilant and visit the field, ordered schools closed in alert districts and directed relief assessments within 24 hours.

The state government had put district administrations, including Lucknow, on alert for the forecast period till Sept 27.

Why it matters: the model-based outlook signals elevated flood risk after an intense downpour, so residents should follow official updates before travelling.
