Central Thailand
A series of flash floods hit different areas of Thailand and Malaysia in 2010. Separate but related floods began in the Northeast and Central Thailand (per the six-region definition) in early October due to abnormally late monsoon moisture over the Bay of Bengal, overflowed the Chao Phraya where the rivers meet, and affected Bangkok, and in the South were triggered by a tropical depression about two weeks later, and was later aggravated by related "La Niña" monsoon rains. Floods subsequently occurred in the Malaysian states of Kedah and Perlis in November 2010.
