A civic official, citing the department’s 8 am forecast, noted that Mumbai could expect "cloudy sky with heavy to very heavy rainfall accompanied with thunderstorm/lightning and gusty winds reaching 40-50 kmph", with the "possibility of extremely heavy rain at isolated places."
Rains began intensifying after midnight, with several areas experiencing intense showers through the night. By morning, the weather had calmed, and most parts of the city were witnessing light to moderate rain, interspersed with occasional heavy spells.
Despite wet conditions, local train services on Central and Western Railway lines remained operational, albeit with some delays. Buses run by the Brihanmumbai Electric Supply and Transport (BEST) undertaking continued without route diversions.
Looking ahead, officials warned of a high tide expected at 2:55 pm, reaching 3.24 metres, and a low tide of 1.31 metres anticipated at 8:50 pm. Typically, heavy rain combined with high tide increases the risk of waterlogging in low-lying zones, while low tide aids faster drainage.
Neighbouring districts — Raigad, Thane, and Palghar — were also placed under a red alert for Sunday, with similar forecasts of intense rainfall. Authorities continue to monitor the situation closely as Mumbai braces for more unpredictable weather in the coming days.
