Taipei, Aug. 1 (CNA)－Daytime temperatures in Yilan are expected to exceed 38 degrees Celsius on Wednesday for a third straight day, according to the Central Weather Bureau (CWB).
Forecaster Liu Pei-teng (劉沛滕) said the CWB has issued a “red light” for Yilan, referring to an alert indicating temperatures of more than 38 degrees for at least three days in a row under the bureau’s new color-coded high temperature alert system.
The CWB’s monitoring station in Tu Chang in Yilan recorded a high of 39.9 degrees on Monday followed by a high of 38.8 degrees on Tuesday.
Because Tu Chang is in a narrow valley that makes it hard for heat to disperse, temperatures have remained high there and Wednesday’s highs could be recorded there again, the forecaster said.
Liu said the mercury in other parts of Taiwan is expected to range between 34 and 37 degrees for Wednesday.
Taiwan is being affected by warm air coming from central and southern China that contains little moisture, which will keep temperatures high, he said.
Liu said the CWB has also issued an orange alert for New Taipei, Taipei, Keelung, Changhua and Hualien, while a yellow light is in effect for Hsinchu, Taoyuan and Miaoli.
An orange light means a forecast of temperatures of more than 38 degrees in a single day or above 36 degrees for three or more consecutive days, while a yellow light signals temperatures higher than 36 degrees for a single day.
Liu warned that many parts of Taiwan will be exposed to dangerously high levels of ultraviolet radiation around the middle of the day Wednesday, and he urged people who need to spend time outdoors to take the necessary precautions.
Thundershowers are possible in mountainous areas around Taiwan and low-lying areas in central and southern parts of the country, in particular in the afternoon, according to Liu.
On Thursday, southwesterly winds are likely to move in to bring rain to central and southern Taiwan, which could last the whole day and destabilize the weather, Liu said.
