The IMD, per the PTI report, said that the progress is expected to bring relief to north India which is currently experiencing a severe heatwave.

Central Maharashtra, including Marathwada, will receive light to moderate rainfall during this time," Sunil Kamble, Head of the Regional Meteorological Department (IMD) in Mumbai told PTI.
