At about 9 pm on May 27, rain began to appear in many inner city areas.
Before the rain appeared, the outdoor temperature in Hanoi always maintained at a high level, and at many times the tunnel surface was slightly hot like a "pot of fire".
For many people in the Capital, this is likened to a "golden rain" in the peak of hot weather.
On many roads, rain came with gusts of wind, causing vehicles to move slowly. Many motorcyclists had to temporarily stop under overpasses or roadside porches to avoid the rain.


Mr. Tran Dinh Phong (27 years old, technology driver) said that in the past few days driving on the street has been torture, the heat from the asphalt road surface is blowing up the tunnel, his clothes are always soaked in sweat.
The rain suddenly poured down and made me feel lighter. Although the rain made the movement a little slower, the air was much cooler and easier to breathe than the stuffy and suffocating heat of the previous few days" - Mr. Phong said.

The National Center for Hydro-Meteorological Forecasting said that on May 28th, due to the impact of a weak cool air mass from mainland China moving down, causing the hot low-lying area in the West to weaken somewhat, the heat in the North will narrow down to only occur in the midlands and delta of the Northern region with the highest temperature commonly 35-37 degrees Celsius, in some places above 37 degrees Celsius.
Forecast for the evening of May 28 and the day of May 29, the Northern region will have rain, locally heavy rain and thunderstorms.
The area from Thanh Hoa to Hue in the next two days will continue to be intensely hot, especially intense in some places with the highest temperature commonly 37-39 degrees C, in some places above 39 degrees C.
The meteorological agency said that from May 29, widespread heat in the North will end, and in the Central region, the heat will gradually subside.
Further forecast, the meteorological agency predicts that from June 1st, the Northern and Central regions are likely to experience widespread heat waves.
