Heavy rains inundated roads and railway tracks on Monday in Mumbai, India's financial hub, prompting authorities to close some schools and colleges. In the northeastern state of Assam, overflowing rivers affected over two million people. Mumbai's municipal body reported that more than 300 mm (11.8 inches) of rain fell within a six-hour period until 7:00 am (0130 GMT). Further heavy showers were anticipated later in the day.

The morning rush-hour witnessed severe traffic congestion on the Eastern and Western Express highways, while the Central Railway cancelled several long-distance trains due to waterlogged tracks. This deluge followed record-breaking rainfall in Delhi, where a fatal airport roof collapse occurred recently.

The monsoon downpours have also triggered floods and landslides in northern and eastern India, along with neighbouring Nepal, resulting in at least 11 fatalities. In Assam, floods have affected more than 2 million people, with Kaziranga National Park, home to rare one-horned rhinos, submerged and six rhinos drowned, according to local authorities.

Since May, at least 66 people have lost their lives in flood-related incidents in Assam. Additionally, flooding has impacted 31 villages in Uttar Pradesh, India's most populous state bordering Nepal, as confirmed by the state government.
