China: Heatwave likely to persist in northern and eastern regions through at least June 25
Heatwave likely to persist in northern and eastern regions across China through at least June 25. Utility disruptions possible.
Event
High temperatures will likely persist across northern and eastern China through at least June 25. As of June 16, the China Meteorological Administration has issued a yellow (second lowest level on a four-tier scale) high-temperature warning across eastern North China Region as well as western Gansu, eastern Guangdong, southeastern and western Inner Mongolia, western Liaoning, and eastern Xinjiang provinces June 16-17; temperatures above 35 C (95 F) are likely. The highest temperatures of 37-40 C (99-104 F) are forecast over Beijing, Hebei, northeastern Henan, southeastern Inner Mongolia, north central and western Liaoning, Shandong, and Tianjin provinces. Forecast models indicate temperatures of more than 35 C (95 F) over the southern North China Region, most of the Huanghuai River, and the central and western parts of Inner Mongolia June 22-25. High temperatures are also likely across Xinjiang Province's southern Xinjiang Basin and Turpan City through June 25. 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.
