Taiwan: Heat wave forecast across eastern, southern, and northern regions through at least May 24
High temperatures forecast in eastern, southern, and northern Taiwan through May 24. Possible transport disruptions and health concerns.
Event
Officials have issued weather warnings for excessive heat due to a heatwave that will persist in eastern, southern, and northern Taiwan through at least May 24. As of May 22, Orange Signal Heat Warnings (the middle level on a three-tier scale) are in place for Tainan City and Taitung County. Daily maximum temperatures of 38 C (100 F) are likely in Taitung County, while daily maximum temperatures of 36 C (99 F) are likely in Tainan City for three consecutive days. Yellow Signal Heat Warnings are in place over the rest of the affected area; daily maximum temperatures of 36 C (99 F) are likely. 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.
