Barring a brief overnight respite, heavy rains accompanied by strong winds continued to lash this commercial capital of India on Wednesday, flooding roads and rail tracks and forcing the closure of schools and colleges - even as most offices functioned with skeletal staff.
According to the weather office, heavy to very heavy rains accompanied by strong winds are expected to hit the city and its suburbs in the next 24 hours to Thursday evening.
The Colaba and Santa Cruz observatories recorded 213.3 mm and 231.0 mm of rain respectively in the 24 hours to Wednesday morning.
Met officials warned fishermen against venturing out to sea as the waters are very rough.
There was some relief on Tuesday night with little or no rain and this led to floodwater receding from most areas, but early morning showers resulted in flash floods in several parts of the city.
Mahalaxmi junction, Kings Circle, Dadar TT, Nair Road, Mumbai Central, Hind Mata, Byculla, Wadala, Kurla, Khar Railway station, Bahar Junction, Sahar Road Andheri Junction were among the areas affected by water logging.
Electricity was cut to 15 places in the city to prevent accidents caused by short circuits.
Suburban train services were discontinued on the Central line due to inundation of tracks. Services on the Western line were running behind schedule.
The Mumbai airport, which was shut down for two hours in the afternoon to repair potholes in the runway, was reopened later in the day. However, several flights were delayed for up to 30 minutes.
Several areas of the city remained water logged, making it difficult for the civic authorities to conduct relief and rescue operations.
The water level at some two-dozen places across the city was between two feet and three feet, civic officials said.
Taking note of the severe disruption, the Bombay High Court on Wednesday rapped the Brihanmumbai Municipal Corporation (BMC) for failing to drain water from low-lying areas and sought action against those responsible for the lapses.
According to Maharashtra Chief Minister Vilasrao Deshmukh, the "situation in Mumbai is under control. The BMC, the police and the fire brigade are doing their best and are informing people on what roads are closed and which ones are waterlogged".
