Adverse winter weather forecast across western Mongolia

Heavy snowfall is forecasted across parts of western and west-central Mongolia from today (27 September).  The Mongolian National Agency for Meteorology and Environment Monitoring (NAMEM) has warned of particularly heavy snowfall in Bayan-Ulgii and Khovd provinces overnight and Zavkhan Province. Hazardous travel conditions are likely due to icy roads and reduced visibility caused by blowing snow.

The NAMEM has issued the following warnings across the affected area:

  • Red heavy snowfall warnings (the highest level on a three-tier scale): Bayan-Ulgii and Khovd provinces.
  • Orange heavy snowfall warnings: Zavkhan Province.
  • Yellow heavy snowfall warnings: Arkhangai, Bayankhongor, Govi-Altai, Khovsgol, and Uvs provinces.

Authorities will likely issue new alerts or update/rescind existing advisories as the weather conditions evolve in the coming days.

In addition to the wintry precipitation, strong wind gusts could lead to periods of blowing and drifting snow. Sporadic power outages are likely throughout the affected area.

The winter weather will likely cause ground and air transport disruptions across the affected area over the coming days. Traffic and commercial trucking delays are possible along regional highways. Difficult and potentially dangerous driving conditions are also likely on secondary and rural roadways in the affected provinces. Authorities could close stretches of highway if driving conditions become too hazardous. Flight delays and cancellations are possible due to strong winds and poor visibility at airports across the affected areas.
