More dark clouds over Nepal

As dusk fell over Kathmandu, the thunderstorm continued unabated. It had been raining continuously for 18 hours, and the forecast said it would keep raining at least till 8am on Sunday.

The Bagmati roared through Chobhar Gorge in awesome rapids – the only drainage outlet for the entire Kathmandu Valley. By evening, 120mm of rain had fallen in 18 hours, more than the average for the whole of October.

Settlements along the banks of Bagmati and Vishnumati in Kathmandu have been evacuated and affected families will be temporarily sheltered in schools across the capital. 

Bagmati Province has set up a Unified Command Team for disaster management while the Home Ministry has instructed CDO and security personnel to be on duty 24/7. 

The torrential rain has obstructed several highways as well as caused infrastructure damage, but no human casualties have been reported so far. Many had feared a repeat of the deadly flashfloods on 28 September 2024 in which 200 people were killed and half of Nepal's hydropower generation capacity siped out.

The government has declared 5 and 6 October as a public holiday to prevent people from travelling during the Dasain festival, and to reduce risk. All highways in and out of Kathmandu closed till Monday. Flood-prone river corridor roads in Kathmandu have been closed after 6PM on Saturday.

Meanwhile, all domestic flights were suspended from Kathmandu and other airports from 2PM Saturday, and most inbound international flights were diverted from 3PM onwards. Rerouted flights started arriving in kathmandu late Saturday as the core of the storm system moved east.

Madhes, Bagmati and Kosi provinces are the worst hit with Maheshpur in Rautahat district recording 270mm of rain as of 3PM on Saturday. Similarly, Gaur received 243.6mm, Kalaiya in Bara 200.6mm and Birganj 221.4mm.

The Department of Meteorology did not blame climate change, but said the unusually heavy precipitation at a time when the monsoon is supposed to have ended was caused by the head-on collision between moisture-laden westerlies with the retreating monsoon.
