Kazakhstan: Annual rainy season underway nationwide through end-November
Annual rainy season underway across Kazakhstan through end-November. Widespread flooding, landslides, and disruptions possible.
Event
Kazakhstan's annual rainy season is underway through at least end-November, bringing an elevated potential for flooding and landslides/mudslides nationwide.
Heavy downpours, flooding, and landslides could affect business, transport, and utility services in many areas. Localized disruptions could persist well after hazardous events have concluded; floodwaters may take days to subside, and debris from mudslides may take weeks to be cleared. Rural communities and informal settlements often sustain the greatest damage and casualties during such events due to poor infrastructure.
The risk of flooding is highest in low-lying communities near watercourses in recognized floodplains. Kazakhstan has several major rivers, including the Irtyish, Ishim, Turgai, and Ural rivers, that could flood during periods of intense rainfall. Flash floods, which can occur with little to no warning, often pose a threat to communities downstream of major rivers, or dams in the event of structural failure. Urban flooding is possible in areas with poorly maintained or inadequate drainage systems, while storm surges may trigger flooding in coastal areas. Landslides and mudslides are possible in hilly and mountainous areas.
Transport
Floodwaters and debris flows may render some bridges, rail networks, or roadways impassable, impacting overland travel in and around affected areas, especially in rural areas, where infrastructure is already of a poor standard. Ponding on road surfaces could cause hazardous driving conditions on regional highways. Authorities could temporarily close some low-lying routes that become inundated by floodwaters.
Severe weather could trigger flight delays and cancellations at domestic and international airports. Flooding could block regional rail lines; freight and passenger train delays and cancellations are likely in areas that see heavy rainfall and potential track inundation. Localized business disruptions may occur; some businesses might not operate at full capacity because of flood damage to facilities, possible evacuations, and some employees' inability to reach work sites.
Advice
Monitor local media for updates and advisories on weather conditions. Confirm all transport reservations (air, ground, and maritime) prior to travel. Make allowances for possible supply chain disruptions throughout the rainy season, particularly in areas affected by flooding and or/landslide events.
Avoid low-lying areas near streams, rivers, and other bodies of water, such as reservoirs, due to the threat of flooding. Do not drive on flooded roads. Exercise caution in elevated terrain due to the threat of landslides and mudslides. Charge battery-powered devices when electricity is available; restrict the use of cellphones to emergencies only during periods of severe weather. Keep any necessary medications in a waterproof container.
