Taiwan: High temperatures forecast in southern regions through at least April 25 /update 1

High temperatures are forecast to persist across southern Taiwan through at least April 25. As of early April 22, the Taiwan Central Weather Bureau has issued orange heat warnings (the middle level on a three-tier scale) for Taitung County and Kaohsiung and Tainan cities; temperatures of up to 36 C (97 F) are forecast for at least three consecutive days. Yellow heat warnings are also in place for the rest of the affected area. Officials could upgrade or expand the alerts over the coming days as conditions change.

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.

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.
