Scorching heat is attacking northern Vietnam, including Hanoi, with temperature likely surging to 37-38 degrees Celsius, and is forecast to last until May 16, the National Center for Hydro-Meteorological Forecasting (NCHMF) said.

The center noted that northern Vietnam has been affected by low-pressure air circulation carrying heat from the west, cranking up temperatures in Hanoi at around 1:00 pm to 37 degrees Celsius, and even higher in some places in mountainous areas.

Foehn wind, caused by impact of the southeastern edge of the western hot low-pressure area, is expected to work with the low-pressure circulation to expand the heat zone to northwestern regions, with temperatures ranging from 38 to 42 degrees Celsius, the NCHMF added.

Northern Vietnam may experience its hottest period from the end of May to July, however, the heat would not be as intense and long-lasting as it was last year, the center stated.

It warned that the ultraviolet index in Hanoi city will remain at the dangerous levels of 8 and 9, posing a high risk of skin damage, including skin cancer, for people exposed to the sun for a long time. Thus, people on the road are recommended to apply SPF 30+ sunscreen, wear a shirt, sunglasses and a hat.

The center’s experts warned that people should prevent probable fire in residential areas as well as wildfire, avoid outdoor activities from 11:00am to 4:00pm, drink water and take proper diet to enhance the immune system.

They also said that as May is still the transitional period from spring to summer, there is a collision between hot and cold waves, so extreme weather may occur such as tornadoes, hail and strong wind in the thunderstorm.
