By late September, the first cold spells are forecast to hit the northern provinces, triggering cooler climate. Temperature in the whole region will drop down by 0.5-1 degree Celsius over the same period in 2019 due to the appearance of cold airs.

At that time, one or two tropical cyclones on the East Sea are likely to trigger downpours across the central region and Central Highlands.

In Hanoi, thunderstorms and heavy rain are forecast to continue until September 8, at nights and in early mornings. People are advised to be on the lookout for storms, lightning and strong winds. The highest temperatures will be from 24 to 28 degrees Celsius.

Earlier, on September 4, the Lao Cai Hydro-meteorology Station recorded the lowest temperature in Sa Pa town, a famous tourist attraction in the province, at 12.9 degrees Celsius. The temperature decreased sharply although the province had not been affected by cold air. This temperature was unprecedentedly low in the series of observed data in the same period, from 1957 up to now.

Meteorologists said the temperature in Sa Pa dropped from the beginning of autumn could be a sign that this year's winter will arrive earlier and is predicted to be much colder than previous years.

Meteorologists informed that a scorching temperature of up to 37 degrees Celsius still hit provinces from Thanh Hoa to Phu Yen.

In the upcoming days, Ho Chi Minh City and the Southern region are expected to experience heavy sky and tropical rains on a large scale.
