The railway authorities suspended the suburban train operations between CSMT-Vashi stations on the Harbour line, CSMT-Kurla on the Main line and also between Churchgate and Kurla due to water-logging on tracks around Masjid Bunder, Kurla, Sion, Marine Line and other stations.

There was “minor disruption” at Palghar from 5.40 am to 7.10 am due to 266 mm rain in two hours and hence, a few trains were regulated enroute, Western Railway’s chief spokesperson Sumit Thakur said.
According to railway sources, suburban services were stopped due to water-logging on tracks at Palghar station.

Bus services of the Brihanmumbai Electric Supply and Transport (BEST), the city civic body’s transport wing, were also affected due to water-logging on some roads.
A BEST spokesperson said their services were diverted on more than 30 routes, including two locations in Thane district, till 9 am.
South Mumbai was badly hit as heavy rains led to water-logging on several roads and low-lying areas and to make the situation worse, several trees fell due to gusty winds, damaging vehicles, officials said.

“The cloud activity indicates that there would be one more intense rainfall day on Wednesday,” Hosalikar tweeted.
Parts of south Madhya Maharashtra and adjoining Marathwada region are also likely to get very heavy rainfall, along with intense spells, he said.
“With formation of low pressure area on Tuesday in North Bay, as forecast by the IMD, it has resulted into strengthening of lower level southerly winds over Arabian sea. It has brought heavy to very heavy rainfall at isolated places in and around Mumbai,” Hosalikar said.
