One picknicker died and at least 106 people were rescued by National Disaster Response Force (NDRF) teams from the Chinchoti waterfall in Vasai in Palghar district on Saturday.
The NDRF personnel, the Fire Brigade, and local police are currently engaged in rescue operations to anchor 12 others stranded to safety.
The waterfall, a popular destination among tourists during the monsoon, is situated in Tungareshwar forest, over 70 kilometres from Mumbai.
"The area is witnessing continuous rainfall since morning which led to these people getting stranded and it is also hampering rescue operations," the official informed.
He said that a team of the 5 Battalion of the NDRF, stationed at Andheri in Mumbai, was provided a "green corridor" by the traffic police to get to the site of operations near Vasai quickly.
