Gusty winds of up to 65 km/h are also expected in several regions alongside the rainfall.

Delhi is also expected to see a change in weather conditions as the wider system moves across north India in the coming days.

Authorities in the affected states have been advised to remain on alert, particularly in low-lying and landslide-prone areas where the risk of disruption is highest.

This marks one of the broader IMD alerts issued this monsoon season, spanning nearly the length of the country from the Himalayan foothills to central and eastern India.

The IMD warned of flash flood risk and heavy to very heavy rainfall across Jharkhand, Uttar Pradesh, Himachal Pradesh and Uttarakhand, with the four states facing the sharpest impact.

Gusty winds of up to 65 km/h are expected in several regions alongside the rainfall, adding to the risk of disruption in the affected areas.
