The south-west monsoon arrived in Mumbai on Wednesday, the IMD announced as heavy rains lashed the country's financial capital and suburbs since early morning.

"It's monsoon arrival in Mumbai today," said Dr Jayanta Sarkar, head of the India Meteorological Department's (IMD) Mumbai office.

Several parts of the city and suburbs witnessed heavy rainfall along with thunder in the morning.

A high tide of over four metres is expected around noon in the Arabian Sea, the Brihanmumbai Municipal Corporation (BMC) said.

The IMD has predicted cloudy sky with moderate rain/ thundershowers in the city and suburbs. There is also a possibility of heavy to very heavy rainfall at isolated places.

Water-logging was reported in some low-lying areas, but the local train services remained unaffected, while routes of some BEST buses run the city civic body's transport wing were diverted.

"It's raining in Mumbai, but trains are running," the Central Railway's chief spokesperson, Shivaji Sutar, said.

As the city continues to get drenched in rain, many Mumbaikars took to Twitter to share videos and pictures of water-logging in their area. Many also shared visuals from their home where they are sitting, enjoying the cool weather.

Here are some of the tweets. Have a look.
