The Thai Meteorological Department on Friday (April 6) warned people in the North, Northeast, East and Central regions as well as Bangkok to brace for summer storms in the next 24 hours.
It said that the four regions and Bangkok would experience thunderstorms with occasional gusty winds, lightning, hail storm and heavy rains in some areas. It advised people in the affected areas to stay away from exposing themselves in the open field, under big trees or billboards.
The Weatherman also predicted the possibility of flash flood and suggested farmers to take steps to protect their crops from damages inflicted by hail storm or strong wind.
It attributed the turbulent weather to strong cold spell from China which has now blanketed upper regions of Laos and Vietnam and is expected to move southward to cover the upper part of Thailand and the South China Sea late today and tomorrow (April 7).
In Bangkok and its peripherals, the Weatherman forecast thunderstorm covering 60 percent of the area tonight until 6 am tomorrow, with heavy rain in some areas. The mercury is expected to drop to 25-26 Celsius.
The northern and northeastern regions are hot but with thunderstorms and rains in 60 percent of the areas.
Some areas will be hit by hail storm and heavy rains. Temperature in the northern provinces is forecast to fall to between 21-24 Celsius and to 22-25 Celsius in the Northeast.
