• Regions likely to experience significant rainfall include the Andaman & Nicobar Islands, Arunachal Pradesh, Assam, Meghalaya, Bihar, Nagaland, Manipur, Mizoram, Tripura, West Bengal, and Sikkim. The rainfall is being driven by a cyclonic circulation over East Uttar Pradesh and adjoining Bihar, along with the monsoon trough extending across northern and central India towards the northeast Bay of Bengal. Thunderstorms accompanied by lightning and gusty winds of 30-40 kmph are also predicted for Bihar, Jharkhand, West Bengal, and Sikkim, while Odisha may experience heavy to very heavy rainfall at isolated locations on 10 September.

Impact & Risks

The heavy rainfall and thunderstorms could lead to waterlogging, localised flooding, and disruptions in daily activities across affected regions. Strong winds may pose risks to infrastructure and transportation, particularly in Odisha, Andhra Pradesh, Tamil Nadu, Puducherry, and Karaikal, where gusts of 40-50 kmph are expected. Residents in low-lying areas and regions prone to flooding should remain vigilant. Agricultural activities may also be impacted due to excessive rainfall in some areas.
