The Thai Meteorological Department has issued a weather warning for the coming days, forecasting a dangerous mix of extreme heat and severe summer storms across much of the country from April 22nd to 27th.

Thailand prepares for a stormy Songkran: Thunderstorms, hail and scorching heat nationwide

The first half of the week will see temperatures soar to blistering levels across upper Thailand, including the North, Northeast, Central, and Eastern regions. Residents can expect sweltering conditions with temperatures reaching dangerously high levels, though isolated thunderstorms and sudden strong winds may still strike in some areas due to a heat-induced low-pressure system.

Conditions are set to turn more violent later in the week. From April 26th to 27th, powerful summer storms are predicted to sweep across upper Thailand, bringing thunderstorms, damaging winds, possible hail, heavy downpours, and frequent lightning strikes. The storms will be fueled by colliding southeasterly and southwesterly winds over the region combined with the ongoing extreme heat.

Meanwhile, the southern provinces face a different threat as rainfall is expected to intensify from April 23rd onward, particularly in the lower South where isolated heavy rain may trigger flash floods. The Gulf of Thailand and Andaman Sea will also turn treacherous, with thunderstorms generating waves over 2 meters high that pose risks to small vessels.

Authorities are urging northern and northeastern residents to take precautions against the approaching storms by avoiding open areas, large trees, and unstable structures when storms hit. All Thais are advised to stay hydrated and limit outdoor exposure during the peak heat hours. Southern communities and boat operators should remain vigilant for sudden heavy rains and rough seas.

This volatile weather pattern comes as Thailand transitions into the peak of its hot season, with the combination of extreme temperatures and unstable atmospheric conditions creating perfect conditions for dangerous summer storms. The Meteorological Department will continue to monitor the situation and issue updates as conditions develop.
