Several states are likely to experience intense rain, thunderstorms, lightning, and strong winds, increasing the possibility of waterlogging, flash floods, and landslides in vulnerable areas.

According to the latest forecast, rainfall activity will continue across Rajasthan, Delhi, Uttar Pradesh, Maharashtra, Kerala, Karnataka, and several other states, while northeastern and eastern India are expected to witness the most intense showers.

The IMD has predicted vigorous monsoon activity over the northeastern region, with several states expected to receive widespread rainfall throughout the day.

The forecast includes:

• Assam and Meghalaya: Heavy to very heavy rainfall at isolated places.

• Arunachal Pradesh: Extremely heavy rainfall is likely in some areas.

• Nagaland, Manipur, Mizoram, and Tripura: Moderate to heavy rainfall accompanied by thunderstorms.

Strong winds and lightning are also expected during the day. Residents in hilly regions have been advised to remain cautious due to the increased risk of landslides, flash floods, and overflowing streams.

Eastern India Likely to Receive Widespread Rain

The weather department has also issued rainfall warnings for several eastern states.

Areas expected to witness significant rainfall include:
