HÀ NỘI — April saw 112 heat records as the country baked in sweltering weather, with many places breaking temperature records set over a decade ago.

Assessing the climate trend for May, Hòa said that the average temperature nationwide was predicted to be generally higher than the average of many years by 1.5-2.5 degrees Celsius.

Also in May, a hot low-pressure system to the west was expected to continue to operate strongly, resulting in many days of intense scorching heat in many provinces, stretching from Thanh Hóa Province to Phú Yên Province.

The Central Highlands and southern regions would continue to experience many days of widespread scorching heat, concentrated in the first 20 days of the month.

"The phenomenon of intense heat nationwide is forecasted to occur more frequently than the average during the same period of the past years," he said.

Thunderstorms in the northern provinces are also expected to gradually increase in May.

Additionally, during the last 10 days of May, the south-west monsoon in the South is expected to become more active, leading to a higher likelihood of increased rainfall in the Central Highlands and southern regions.

He warned that people should be vigilant against dangerous weather phenomena such as thunderstorms accompanied by hail, lightning, hailstorms and strong gusts of wind. — VNS
