The IMD has classified the yellow alert as an indication of possible weather conditions that could disrupt daily life for residents. On the same day, the IMD forecasted a generally cloudy sky for Mumbai, with moderate rainfall and potential thunderstorms accompanied by lightning across the city and its suburbs.
