Northern Vietnam has entered what was forecast to be the hottest period so far this year, as a hot spell started baking the region on Tuesday.
A thermal low located west of the country has been expanding its effect towards the southeast direction, resulting in intense heat in northern Vietnam as well as some north-central provinces, according to the National Center for Hydro-meteorological Forecasting.
The hot weather pattern was forecast to last from June 19 to 23.
Average highs in the northern region, including Hanoi, are expected to be between 35 and 38 degrees Celsius, and can reach up to 39 degrees Celsius in north-central localities.
The bolstering atmosphere can be felt from 11:00 am to 4:00 pm every day.
On Tuesday, the first day of the hot period, temperatures in most northern and north-central provinces were recorded from 36 to over 37 degrees Celsius.
In Hanoi, mercury soared to about 36 to 37 degrees Celsius at noon, from only 29 degrees Celsius in the morning.
Aside from the heat wave, rainfall accompanied with gusts and hails will occur in the region in the next two to three days, mainly during the evening, said Hoang Phuc Lam, a senior official of the national forecast center.
From June 24 to 26, temperatures will begin to drop and it will be raining more regularly throughout the day, Lam added.
