Flash floods damaged power substations, while parts of the capital of Umnugovi and counties of Khankhongor, Khanbogd, Gurvantes, Nomgon and Tsogttsetsii are still without power on July 29. Currently, 20 employees of the Southern Region Electricity Distribution Network company are working to repair the damaged stations. Heavy rains on July 24 also caused severe flash flooding in Govi-Altai province, where, tragically, five people died and six households saw their gers destroyed.
According to the National Meteorology and Environmental Monitoring Agency, due to heavy rains, most rivers in Mongolia have water levels 10 to 120 centimeters above normal, and they are expected to rise further.
Prolonged rains across the country are affecting both urban and rural areas of Mongolia. In Ulaanbaatar, the capital of Mongolia, some areas were badly damaged and overwhelmed by heavy rains, causing massive stress among the citizens.
