The weather warning issued on Sunday indicated a high pressure system originating from China prevailed over the upper part of the country with hot weather covering Thailand.
The hot weather was forecast to cause summer storms with possible isolated thunderstorms, gusting wind and hail, especially in the Northeast and the North on April 22 through 23.
Residents were warned to beware of severe weather.
Meanwhile, southwesterly winds caused scattered thundershowers over the Andaman Sea and the South.
In a related development, a summer storm struck Buri Ram’s Krasang district, destroying 50 houses in five villages, roadside lampposts, barns and a local child care centre as well as felling trees.
Twelve out of the 50 houses were completely destroyed by the storm, according to Manop Juprakhon, chief of Khokkhamin Subdistrict Administrative Organization. Damage assessment and housing repairs are underway.
Meanwhile, in the northernmost province of Chiang Rai, severe drought continued.
