“Our models are showing that Odisha, Jharkhand, east Uttar Pradesh, Chhattisgarh, Bihar will be badly impacted by the heat wave,” explained a senior scientist of the national weather forecasting centre at IMD - New Delhi. He added that a feeble western disturbance was approaching around April 28 but that it won't offer any relief.
