The southwest monsoon is poised to make further progress across India over the next few days, bringing widespread rainfall to large parts of the country even as heatwave conditions continue to grip sections of northwest and central India. The India Meteorological Department (IMD), in its latest All India Weather Summary and Forecast Bulletin issued on Monday, has forecast extremely heavy rainfall over parts of Karnataka, heavy rain across much of southern and northeastern India, and thunderstorms accompanied by strong winds in several states.
