Mumbai received its first widespread pre-monsoon showers on Sunday, bringing a welcome respite from weeks of oppressive heat and humidity. The India Meteorological Department (IMD) confirmed that while these showers were significant, the southwest monsoon has not yet arrived, issuing a yellow alert for thunderstorms, rain, and gusty winds until June 2. The eastern suburbs experienced the heaviest rainfall, averaging 5 mm, while the western suburbs saw 2 mm and the island city only 0.61 mm. IMD scientist Nitha Sashidharan explained that the showers were caused by strong westerly winds and a western disturbance affecting weather patterns in northern India and the Arabian Sea. Light showers are expected over the next few days, with temperatures gradually decreasing, although they remain above seasonal averages. Residents in Mumbai and surrounding areas, including Thane, Palghar, and Raigad, have been advised to stay alert for intermittent thunderstorms and brief moderate rain in the coming days.
