Extreme Heat of 38°C in New Taipei, Tainan, and Hualien; Wu Der-rong: Rain and Cooling Expected on the 29th

Taiwan's Central Weather Administration issued high-temperature information today for 12 counties and cities, including Greater Taipei. New Taipei City, Tainan City, and Hualien County are warned of potential extreme heat of 38 degrees Celsius. Weather expert Wu Der-rong stated that the fourth Meiyu front of the season will move south tomorrow, bringing rain and cooling temperatures. The Central Weather Administration issued a high-temperature alert, noting hot and sunny weather. During the day today, New Taipei, Tainan, and Hualien were under a red alert, with a chance of continuous extreme heat of 38 degrees Celsius. Keelung, Taipei, Taoyuan, Hsinchu County, Miaoli, Changhua, Kaohsiung, Pingtung, and Taitung were under an orange alert, with a possibility of continuous 36-degree heat. Wu Der-rong, an adjunct associate professor in the Department of Atmospheric Sciences at National Central University, wrote in his column 'Weather Secret Classroom' that the latest European model (ECMWF) simulations show that the stationary front is gradually moving south to the northern sea area today. Taiwan is within a warm air mass with low moisture and stable atmosphere. Although the peak has passed, temperatures will only drop slightly, and the daytime remains as hot as midsummer, so precautions against sunburn and heatstroke are necessary. Wu pointed out that the latest model simulations show the fourth Meiyu front moving south tomorrow, bringing rain and cooling. On the 30th, the front will be disrupted and move south to the Bashi Channel, with weather improving to cloudy to sunny across the country. Convection will develop in the mountainous areas of central and southern Taiwan in the afternoon, potentially affecting some plains. On the 31st, weather will remain sunny to cloudy. Wu mentioned that the latest model simulations show that on June 1, the northeasterly winds from the periphery of Typhoon Jangmi will bring moisture, causing local short-term rain in the north and northeast. On June 2, moisture will decrease, with occasional rain possible on the north coast and northern mountainous areas, while other areas will be cloudy to sunny. He mentioned that from June 3 to 6, Jangmi will have moved away, and the southwest monsoon will enter the South China Sea, causing Taiwan's temperatures to rise day by day, the atmosphere to become increasingly unstable, and the probability of afternoon rain to increase daily. Wu pointed out that the latest path forecast from the Central Weather Administration shows that the 6th mild typhoon, Jangmi, is moving northwest and then north, reaching the sea southeast of Ryukyu at 2:00 AM on June 2. The latest European model and ensemble path simulations show that Jangmi's average path will pass near Ryukyu and gradually turn northeast, posing no direct threat to Taiwan. However, he reminded that the red box in the forecast map and the paths of individual ensemble members all show uncertainty in the predicted path, and it should be continuously observed.
