China: Heat warnings in place for southern, central, and northwestern regions through at least July 9
Officials issue heat warnings across southern, central, and northwestern China through at least July 9. Utility disruptions possible.
Event
Officials have issued weather warnings for excessive heat across southern, central, and northwestern China through at least July 9. Authorities have warned that temperatures of more than 35 C (95 F) over 3-5 days are possible in Gansu, Guanzhong, western Inner Mongolia, Ningxia, and Xinjiang provinces.
As of early June 29, the China Meteorological Administration has issued yellow (second-lowest level on a four-tier scale) high-temperature warnings for northern Anhui, central and northern Chongqing, central and northern Fujian, western and southern Gansu, central Guangdong, Hainan, western and southern Henan, most of Hubei, northern Hunan, western Inner Mongolia, eastern and southern Jiangxi, central and eastern Sichuan, central and southern Shaanxi, southern Shanxi, most of Xinjiang, and eastern Zhejiang provinces, where temperatures of 35-36 C (95-97 F) are possible. Higher temperatures of more than 40 C (104 F) are possible in the southern Xinjiang Basin while temperatures of 37-39 C (98.5-102 F) are likely in northeastern Chongqing, northern Fujian, western Henan, western Hubei, some parts of northern Hunan, western Inner Mongolia, southern Shaanxi, and central Sichuan provinces as well as the northern side of the Tianshan Mountains in Xinjiang Province. Officials could upgrade or expand the alerts over the coming days as conditions change.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. Heatwaves also threaten 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' hospitalization.
Transport and Utilities
Very high temperatures may damage road surfaces, 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 engines, 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.
Advice
Monitor local media for weather updates and related advisories. During heatwaves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well-hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating; drink bottled or boiled water. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in the case of prolonged electricity outages.
