Taipei, June 26 (CNA) Clear and sultry weather is expected across Taiwan on Tuesday, with temperatures of over 35 degrees Celsius forecast for Taipei, mountainous areas in western Taiwan, and the East Rift Valley, the Central Weather Bureau said.
The bureau has issued an orange alert for Taipei and Hualien, which have recorded a high temperature of 36 degrees for three consecutive days.
A yellow alert, meanwhile, has been issued for Kaohsiung.
Due to strong convection in the atmosphere, there is a chance of downpours in mountainous areas in the afternoon, according to the CWB.
Under the bureau's new color-coded high heat alert system, a yellow light signifies temperatures of 36-38 degrees for less than three consecutive days and warns people to avoid spending too much time outdoors.
An orange light means temperatures of over 38 degrees are expected the following day or if the mercury is forecast to remain above 36 degrees Celsius for three or more consecutive days, and warns people to avoid unnecessary outdoor activities.
In circumstances where temperatures are forecast to remain above 38 degrees for three or more consecutive days, the light will flash red, warning residents to avoid going outdoors.
Ultraviolet levels are also expected to hit dangerously high levels Tuesday, with a UV Index reading of 11, or extreme risk of harm from unprotected sun exposure, forecast for eastern and southwestern Taiwan around midday.
The UV index could reach 10, representing a "very high" risk of harm from unprotected sun exposure, in Greater Taipei.
The air quality was fair in the Greater Taipei area Tuesday but was expected to worsen to unhealthy for sensitive groups later in the day. It is expected to be fair but with high PM2.5 concentrations in southwestern Taiwan.
