Heavy showers lashed several parts of Mumbai on Sunday, July 19, as the India Meteorological Department (IMD) forecast continued rainfall across the city accompanied by thunderstorms, lightning, and gusty winds. The weather department has advised residents to remain cautious, as intermittent rain is expected to continue throughout the day. The renewed spell of monsoon showers has brought relief from humid conditions while also raising concerns over possible waterlogging and traffic disruptions in low-lying areas.

According to the IMD, Mumbai is likely to experience generally cloudy skies with periods of moderate rainfall, along with thunderstorms at isolated locations. The department has also warned of lightning and strong gusty winds during intense spells of rain. Civic authorities are closely monitoring the situation and have urged citizens to stay updated with official weather advisories, especially while travelling during adverse weather conditions.

The city had witnessed generally cloudy weather with occasional light to moderate rainfall on Saturday before the intensity of the showers increased again. The return of widespread rainfall marks the continuation of the southwest monsoon over the financial capital after a brief lull. Rainfall activity has remained uneven across different parts of Mumbai, with some areas receiving significantly higher precipitation than others.
