Taiwan issues high-temperature warnings for 12 areas; 'leeward vortex' could push Taipei temps higher

Taiwan is bracing for intense heat as the weather agency elevated high-temperature warnings to include 12 counties and cities, with four areas facing an orange alert signifying the likelihood of consecutive days reaching 36 degrees Celsius (97 degrees Fahrenheit). The Central Weather Administration issued the updated alert, attributing the scorching conditions to the descending air currents from the periphery of a typhoon.

Adding to the concern, former Meteorological Bureau Director Zheng Ming-dian highlighted the presence of a "leeward vortex" north of Taiwan. He explained that this phenomenon, influenced by the descending air on the leeward side of mountains, could lead to exceptionally high temperatures in the greater Taipei region. This vortex is reportedly driven by the easterly winds associated with a high-pressure system, rather than a large typhoon.

As of midday, the highest recorded temperature was 36.1°C in Taoyuan City's Luzhu district, with New Taipei City's Tamsui also reporting a high of 36.0°C. The authorities are urging the public to limit non-essential outdoor activities and exercise, emphasizing the importance of sun protection and adequate hydration to prevent heatstroke. Indoor spaces should be kept ventilated and cool, with suggestions for using fans or ice packs for relief.

Special attention is being directed towards the elderly, children, individuals with chronic illnesses, the obese, those on medication, and other vulnerable populations, who are advised to stay away from high-temperature environments. For agricultural sectors, measures such as windbreaks and water spraying are recommended to mitigate potential crop damage caused by the extreme heat and potential Foehn-like winds.
