Taiwan: Heatwave forecast across most regions through at least July 18 /update 2
High temperatures forecast across Taiwan through at least July 18. Transport disruptions and health concerns possible.
Event
Officials have issued weather warnings for excessive heat due to a heatwave that will persist across most of Taiwan through at least July 18. As of early July 12, the Central Meteorological Bureau of Taiwan has issued Orange Signal Heat Warnings (the middle level on a three-tier scale) for Pingtung and Yunlin counties as well as Kaohsiung and Tainan cities. Yellow Signal Heat Warnings are in place over Hualien County and Taipei City. Temperatures of at least 36 C (97 F) are likely, especially in southern and eastern Taiwan. The high temperatures are forecast to persist in many areas through at least July 18. 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 airports in the region, 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.
