Catastrophic flooding triggered by above-average monsoon rainfall has displaced over three million people across three South Asian countries, prompting governments and international aid organizations to mobilize one of the largest relief operations in recent years. The floods, described by meteorologists as a once-in-50-year event, have claimed more than 400 lives and submerged entire districts under several meters of water.

Helicopters from military and civilian agencies are conducting continuous rescue operations in areas cut off by floodwaters, while temporary shelters have been established in schools and government buildings on higher ground. The Red Cross and Red Crescent societies have activated their emergency response protocols.

Climate scientists have linked the severity of the flooding to above-average sea surface temperatures in the Indian Ocean, consistent with patterns associated with climate change. This is the third major flooding event in the region in four years.
