The heatwave is increasing its intensity across northern localities, including the capital city of Hanoi, sending daytime temperatures climbing to 35 - 37°C, and above 38°C with low humidity of 55 - 60%.

From June 16, the heat is expected to ease slightly due to evening thunderstorms, but temperatures will still remain high at around 34 - 35°C.

These storms may be accompanied by gusty winds, lightning, and hail, particularly in mountainous and midland northern areas.

In the central region, the heat is intense and prolonged through June 15 - 16, with similar or even higher temperatures than the North, exceeding 38°C in some areas.

Relative humidity stays low at 50 - 60%, causing a muggy, uncomfortable feeling and increasing the risks of fires, explosions, and heat-related illnesses like exhaustion or heatstroke. The hot spell in the central region is anticipated to last for several days till June 19-20.

According to meteorologists, while typhoon Wutip was active over the East Sea, it pulled in moist air and caused widespread rain, which temporarily disrupted hot weather conditions. However, after the typhoon weakened and made landfall in China, its circulation collapsed, allowing other dominant weather patterns to re-emerge and influence local weather.

The subtropical high-pressure system which typically causes hot, dry, cloudless weather expanded westward, covering Northern and Central Vietnam. The system suppressed cloud formation, leading to clearer skies, stronger solar radiation during the day and rapid temperature rise.

Local residents are advised to limit outdoor activities during peak heat hours from 11:00 AM to 4:00 PM; drink plenty of water and replenish electrolytes to prevent dehydration and heat exhaustion; and minimise the use of high-powered electrical appliances for fire safety reasons.

Torrential rain lashes north, heatwave bakes central region

VOV.VN - Heavy rain is expected to blanket Northern Vietnam from June 9 afternoon through June 10 morning, while the central region is being battered by a heatwave, with temperatures hovering above 37°C, said meteorologists.
