China: Heatwave likely to persist in central, eastern, and northern regions through at least June 30
Heatwave likely to persist in central, eastern, and northern China through at least June 30. Utility disruptions possible.
Event
High temperatures will likely persist across parts of central, eastern, and northern China through at least June 30. As of June 26, the China Meteorological Administration has issued a yellow high-temperature warning (the second lowest level on a four-tier scale) across parts of northeastern, eastern, and central China, as well as isolated pockets of far northern, northwestern, and southwestern China; temperatures above 35 C (95 F) are likely across the affected areas. Temperatures of 37-39 C (99-104 F) are forecast in parts of central Shaanxi Province, the central and southeastern Sichuan Basin, northeastern Yunnan Province, and eastern Xinjiang Region and could reach more than 40 C (104 F) in central Hebei Province, southeastern Beijing Municipality, and western Tianjin Municipality. 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.
