"Increased rainfall activity over coastal Karnataka, Goa and south Maharashtra is likely to continue till June 10. It is very likely to extend to north-coastal Maharashtra, including Mumbai, from tomorrow. Extremely heavy rainfall at isolated places in these regions is very likely during this period," the IMD said, adding rainfall is likely to reduce from June 12.
