The country's western coast has been inundated by torrential rains since Thursday, with the India Meteorological Department warning of further downpours over the next few days, according to AFP.
Flooding and landslides are common during India's treacherous monsoon season, which also often sees poorly constructed buildings buckle after days of non-stop rain.
Experts say climate change has caused the annual deluge to increase in frequency and intensity.
In Maharashtra state, 117 people have been killed, including more than 40 in a large landslide that hit the hillside village of Taliye some 250 kilometers (155 miles) southeast of Mumbai Thursday.
Villager Jayram Mahaske, whose relatives remained trapped, told AFP that “many people were washed away as they were trying to run away” from the landslide.
Another villager, Govind Malusare, said his nephew’s body had been found after the landslide hit his family’s home, but that his mother, brother, sister-in-law and niece were still missing.
The landslip flattened dozens of homes in a matter of minutes, leaving just two concrete structures standing and cutting off power, local residents told AFP.
In Posare village 210 kilometers south of Mumbai, the National Disaster Response Force said four bodies were found overnight.
In parts of Chiplun, water levels rose to nearly 20 feet (six meters) on Thursday after 24 hours of uninterrupted rain. The water levels have since started to recede.
Eight patients at a local COVID-19 hospital also reportedly died after power supply to ventilators was cut off.
Rescuers were working in waist-deep mud to search for 100 people still missing in the state with the help of excavators.
In neighbouring Goa, a woman was feared to have drowned from the flooding, officials said, in what Chief Minister Pramod Sawant said were the "worst floods since 1982".
In the coastal plains spanning Maharashtra and Goa, floodwater levels remained elevated after rivers burst their banks and forced terrified residents to seek safety on rooftops and upper floors.
Further south in Karnataka state, the death toll rose to nine overnight, with four others missing, officials said.
Power supply was disrupted in the 11 affected districts and there were crop losses across vast swathes of land.
Climate scientist Roxy Mathew Koll of the Indian Institute of Tropical Meteorology said climate change was warming the Arabian Sea.
The higher water temperatures were causing the air above to become warmer and hold more moisture, sparking more extreme rainfall events, he said.
“We are seeing a three-fold rise in widespread extreme rainfall events... since 1950,” Koll told AFP, citing a study he co-authored that was published in Nature.
He added that a hill station south of Mumbai, Mahabaleshwar, reported 594 millimeters of rain on Friday – the highest since the start of records a century ago.
“In recent years, the impact of climate change (on monsoons in India) is much more obvious. In fact, what has happened in Europe, China and the rest of the world is similar to what’s happening in India.”
