Torrential Rain and Flash Floods

Thailand Climate
According to the UK weather agency Meteorological Office (Met Office), Thailand is currently in its monsoon season (wet or rainy season), which spans from May to October.
The country normally has warm weather throughout the year, but significant "variations" occur during the wet season.
During the rainy season, Thailand's weather is dominated by the southwest monsoon, which transfers humid air to the country via the Indian Ocean.
The monsoon causes a substantial amount of rainfall released in short bursts during the afternoon or evening for each day, says the Met Office.
Furthermore, the UK weather agency emphasized that September and October are the months to receive the heaviest rainfall. In the case of severe or extreme weather, rainfall during the season may also bring strong onshore winds.
Previous Torrential Rain
The worst recorded rain in Thailand within three decades occurred in 2017 when severe flooding submerged villages in the country.
At least 12 people were killed and hundreds of thousands of people were affected as floods reached the level of a house roof, as per the BBC.
In September 2021, heavy rain triggered flash floods and severe flooding across multiple parts of Thailand, killing six people; five in the central Lopburi region and one in Phetchabun.
30 other provinces have been affected by the severe weather event with more than 24 provinces declared disaster zones.
Prior to the disaster, Thailand officials issued flood warnings nationwide.
The storm affected more than 120,000 households in 30 provinces, according to the DDPM, as cited by the Associated Press.
Last year's downpour was caused by a severe tropical storm. This entails that either monsoon or storm-related torrential rain may occur again in Thailand in the coming months.
During this period, low-lying and mountainous areas are at risk due to flooding and landslides.
