Mumbai witnessed heavy rains for the second consecutive day on Friday causing major traffic snarls. This also led to disruption of the suburban train services. "There is water logging in low lying areas like Dadar, Parel, Sion, Kurla, Ghatkopar and the Western Express Highway which has caused severe disruptions in vehicular traffic along the stretches. The MCGM is trying to pump out water from these areas so that the situation can be normalised," a senior official of the Municipal Corporation of Greater Mumbai (MCGM) said.
