Mumbai will continue to witness heavy to very heavy rainfall over the next four days, the India Meteorological Department (IMD) said on Monday, attributing the intense showers to multiple weather systems currently active over the Bay of Bengal, Arabian Sea and the West Coast.

According to IMD, a well-marked low-pressure area persists over the west-central and adjoining northwest Bay of Bengal, stretching across north Andhra Pradesh and south Odisha coasts, with an associated cyclonic circulation up to 9.6 km above mean sea level.

An upper-air cyclonic circulation also lies over the northeast Arabian Sea and Gujarat, while a shear zone along latitude 19°N and an offshore trough from south Konkan to north Kerala are further enhancing the monsoon activity.
