HANOI, July 11 (Xinhua) -- The Ultraviolet (UV) Index in most provinces and cities in Vietnam hit very high risk levels on Tuesday, according to the National Center for Hydrometeorological Forecasting.
Ha Long, Hai Phong and Hanoi cities in the north; Hue, Da Nang, Hoi An and Nha Trang cities in the central; and Ho Chi Minh City in the south saw UV Index levels rise to 9 and above on Tuesday, Vietnam News Agency reported, citing the center.
