Over the next five days, East India and South Peninsular India, including states like West Bengal, Karnataka, Odisha, Tamil Nadu, Bihar, Sikkim, Telangana, Uttar Pradesh, and Jharkhand, are expected to experience severe heatwaves. Additionally, high humidity levels along the coasts of Andhra Pradesh, Tamil Nadu, Puducherry, Karnataka, Goa, Kerala, Assam, Meghalaya, Tripura, and Bihar could intensify discomfort due to the heat.
