Weather officials have warned of dangerous thunderstorms in Hanoi and widespread heavy rainfall across northern Vietnam, with localized downpours exceeding 250mm.

Forecasters warn that parts of northern Vietnam could receive more than 300 mm of rain, raising the risk of flooding, flash floods and landslides.

Northern Vietnam is expected to face two rounds of heavy rain over the coming week, while a tropical depression has a 70% chance of entering the East Sea from July 1, weather authorities said.

As El Nino is forecast to intensify and persist through the end of the year, experts have warned people not to underestimate the health impacts of extreme weather, particularly on the cardiovascular system.

Super Typhoon Mekkhala has intensified to Category 16 strength east of the Philippines, becoming the most powerful storm to form in the northwestern Pacific during June in more than two decades, according to Vietnamese meteorologists.

Typhoon Mekkhala is expected to strengthen into a super typhoon within the next 24 hours, though forecasters say the powerful storm currently shows no signs of heading toward Vietnam.

Vietnam’s weather authorities are closely monitoring Tropical Storm Mekkhala, which is forecast to become a powerful storm but remains far from Vietnamese waters.

Meteorologists warn that a powerful El Nino event could bring hotter temperatures, reduced rainfall and heightened climate risks to many parts of Vietnam.

Vietnam is expected to face hotter-than-average temperatures, intensified heatwaves and increasingly unpredictable storms during the second half of 2026 as El Nino strengthens.

A rare cold front moved into northern Vietnam on the evening of June 8, triggering widespread heavy rain and a sudden drop in temperatures across the region.

A late-season cold air mass is set to bring widespread heavy rain and cooler temperatures to northern Vietnam, raising concerns over flash floods and landslides.

The first tropical depression of 2026 in the East Sea is currently about 500km from the Hoang Sa Islands and moving rapidly toward the northeast. Forecasters say there is very little chance it will affect Vietnam's mainland.

After the most intense late-May heatwave in five years, Vietnam is bracing for an even hotter summer under emerging El Nino conditions.
