Deadly Cloudburst-Induced Flood Hits Mountainous Village in Uttarakhand, Dozens Missing
A deluge of floodwaters swept through a mountainous village in Uttarakhand, India’s northern state, on Tuesday, resulting in at least four fatalities and several individuals reported missing, according to local officials.
Striking footage from the Himalayan village of Dharali depicts a torrent of water, mud, and debris cascading down the mountainside and through the village, obliterating homes and businesses in its path. The flooding occurred around 1:45 p.m., as per Uttarkashi District Magistrate Prashant Arya’s statement.
At least four individuals were confirmed dead by Arya. “The region is home to numerous guest houses, restaurants, and hotels,” he explained, “which led us to immediately request the military’s assistance in rescue operations.”
By Tuesday evening, at least 20 individuals had been rescued, while search efforts continued for those still missing. Lt. Col. Manish Shrivastava, a defense spokesperson in Uttarakhand, reported this shortly after the disaster.
Preliminary estimates suggest that dozens of people may be trapped or unaccounted for, and many homes have been destroyed. Authorities are working to determine the exact number of individuals missing or requiring rescue. Arya stated that around a dozen hotels were washed away in Tuesday’s flood, as reported by the Associated Press.
Arya attributed the devastation in Dharali to a sudden downpour, also known as a cloudburst. “There is a river there,” he explained, “and due to the cloudburst, an excessive amount of water poured in unexpectedly.”
Cloudbursts are characterized by extreme rainfall in localized areas and typically result in flash flooding. They commonly occur in the foothills of the Himalayas and are exacerbated by the region’s topography, making the flooding even more dangerous. The India Meteorological Department defines a cloudburst as an event with rainfall exceeding 100 mm (4 inches) per hour.
Cloudbursts can cause extensive damage and destruction due to the rapid funneling of immense amounts of water through mountains and valleys into villages.
Although not yet confirmed, this flooding may have been caused by a cloudburst. Other possible causes include glacial lake outbursts, dam failures, or sudden releases of water from upstream reservoirs. Glacial lake outbursts occur when natural ice dams weaken and collapse, sending sudden, unanticipated torrents of water down steep terrain. They are most likely to happen during this season.
The India Meteorological Department issued its highest level of warnings for “extremely heavy” rainfall across Uttarakhand. Portions of the state, particularly those prone to flooding, received as much as 300 mm (12 inches) of rainfall in the 24 hours leading up to Tuesday morning.
India’s agricultural sector and livelihoods heavily rely on the annual monsoon rains that occur from June through September. However, these heavy summer storms can also result in such torrential downpours and flooding that the region’s infrastructure struggles to manage.
