Kazakhstan, Uzbekistan: High temperatures forecast to persist across much of Kazakhstan and Uzbekistan through at least July 1

Forecast models indicate that high temperatures will persist over much of Kazakhstan and Uzbekistan through at least July 1. Temperatures in excess of 40 C (104 F) are expected across parts of the region over the coming days.

As of June 26, Kazakhstan's National Hydrometeorological Service (Kazhydromet) has issued red high-temperature warnings (the highest level on a three-tier scale) across part of Almaty, Jetisu, Kyzlorda, and Ulytau regions, indicating temperatures of over 40 C (104 F) in these areas. Orange high-temperature warnings are in place for parts of Abai, East Kazakhstan, Karaganda, and Ulytau regions. Yellow high-temperature warnings have been issued for part of Akmola and Mangystau regions. Further red, orange, and yellow high-temperature warnings are in place over parts of central, eastern, and southern Kazakhstan June 27-28.

Uzbekistan's Hydrometeorological Service has forecast daytime temperatures of 37-42 C (99-108 F) in Qashqadaryo and Surxondaryo regions in southern Uzbekistan over the coming days. Temperatures of 33-39 C (91-102 F) are expected in central and eastern regions and 28-35 C (82-95) in northwestern regions. Slightly cooler temperatures are likely in mountainous areas of the country.

The high temperatures may result in increased energy and water demand and a heightened risk of heat-related illnesses, such as heat exhaustion and heat stroke.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for further wildfire growth throughout the affected areas. Heatwaves also pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers being hospitalized for dehydration.

Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on vehicles, making tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
