Thailand will officially enter rainy season at the end of this month and the rain situation this year will be normal without an El Nino phenomenon with sufficient water for agriculture, according to the prediction of the Meteorological Department.
Department head Mr Wanchai Sak-udomchai said on Monday that rainfall this year would not be too much to cause widespread flooding or too little that would cause widespread drought.
However, during the start of the rainy season expected at the end of this month, the amount of rainfall might be slightly more than normal and, eventually, it would decrease in September and October.
Regarding the current weather situation, Mr Wanchai said the northern region would experience freak storms for the next few days, resulting in heavy rains in some parts of the region.
In other regions, there will be rains in some parts after which the temperature will slightly increase during the second week of May, but it will not be as hot as it was as reported in April and early May.
Northern provinces vulnerable to freak summer storms in the next few days are Mae Hong Son, Chiang Mai, Chiang Rai, Phayao, Lamphun, Lampang, Tak, Phichit, Sukhothai and Kamphaeng Phet.
