India’s High Commission in Islamabad notified Pakistani authorities at about 10:00 a.m. local time on 24 Aug. that a heavy discharge from the Tawi River in Jammu could trigger significant flooding downstream in Pakistan, according to officials quoted by Geo News. The warning was delivered under the Indus Waters Treaty, the 1960 accord that governs the two countries’ shared rivers. Government sources in Islamabad said the message represents the first substantive bilateral contact since the brief India-Pakistan war in May. Pakistani agencies have issued local alerts based on the Indian information. The notice comes as Pakistan is already battling severe monsoon flooding that has killed nearly 400 people since mid-August, Reuters reported. Authorities are also monitoring a landslide-dammed lake that threatens to burst, compounding the risk to low-lying communities.
