Relentless monsoon rains have triggered widespread flooding and landslides across India and Pakistan, disrupting transport, severing power and killing hundreds. The downpours span from Maharashtra’s coast to the Himalayan foothills and Pakistan’s northwest, with forecasters warning that the weather system is likely to remain intense for several more days. In India, the India Meteorological Department placed Mumbai, Thane, Raigad and neighbouring districts under a red alert after three days of heavy rainfall. The Brihanmumbai Municipal Corporation closed all afternoon-shift schools and colleges on Monday, while waterlogged streets paralysed the Western Express Highway and forced Central Railway to clamp points at several harbour-line stations. State officials said red or orange alerts cover roughly half of Maharashtra’s districts until at least 21 August. Further north, multiple landslides blocked the Chandigarh–Manali National Highway and cut off at least 15 panchayats near Pagal Nala in Kullu, Himachal Pradesh. Authorities in Jammu, Kashmir and Himachal Pradesh shut schools and warned of more cloudbursts after rivers in the region rose sharply. All 18 spillway gates of the Hathinikund Barrage in Haryana were opened for the first time this season as the Yamuna crossed the danger mark, and low-lying areas of Delhi, Moradabad and Kanpur reported fresh inundation. Pakistan is contending with its deadliest monsoon in years. The National Disaster Management Authority said 657 people have died and 929 have been injured in rain-related incidents since 26 June, with Khyber Pakhtunkhwa accounting for 390 of the fatalities. Provincial authorities closed schools again on Monday, while army units deployed to Buner, Swabi and other hard-hit districts to search for bodies and deliver tents, generators and medicines. Prime Minister Shehbaz Sharif directed federal agencies to accelerate relief supplies, and Khyber Pakhtunkhwa Chief Minister Ali Amin Gandapur pledged his August salary to flood victims. Both the IMD and Pakistan’s Meteorological Department expect the strong monsoon system to persist through at least 22 August, raising the risk of further landslides, river overflows and infrastructure damage on both sides of the border.
