All-time temperature records were broken in Vietnam and Laos last week. On 6 May, Hoi Xuan in Vietnam reached a scorching 44.1C, breaking the previous record for the country of 43.4C, set in 2019. On the same day, Laos recorded its highest-ever temperature, , which reached 43.5C in Luang Prabang. These records were set just a few weeks after temperatures in Thailand rose above 45C for the first time.
A breakdown of the heat in south-east Asia is expected to occur in the next few days as a tropical disturbance is likely to develop nearby. Forecast models suggest that, over the coming days, the Bay of Bengal will have the perfect conditions for cyclogenesis to occur. By later this week, several factors, including enhanced vorticity and very high sea surface temperatures, will enhance the chance that a tropical storm will edge north-eastwards into parts of Myanmar. This will bring some strong winds and significant rainfall to south-east Asia, including the areas that have recently seen their temperature records broken.
