The rainy season officially began on May 16th. However, there are remaining water reservoirs yet to be filled, particularly in the northern provinces. Overall, the after effects of drought experienced in the previous months are not yet over in terms of economy, since prices of commodities increased and crop production significantly lowered.
Economic Loss
The total economic loss from drought could reduce Thailand’s GDP by 0.5%, according to the Economic Intelligence Centre of Siam Commercial Bank (EIC), and up to 80 million Baht in economic damage was lost during the first three months of the year alone, mainly from agricultural loss.
Flood Risk in 2016
Thailand would be at risk from flooding during the second half of the year 2016, GISTDA forecasts. Two to three tropical cyclones are expected to head towards Thailand during the rainy season which will lead to floods. Potential affected areas include Prachinburi, Ayutthaya, Suphanburi, and Pitsanulok, of which are lowlands that have experienced major flooding in 2011. Flooding is likely to occur during August until October. The wet season could last as long as 15 months due to La Niña, characterized by lowering temperatures accompanied by more rain in the region. Heavy rain may drag on until 2017. However the extent of the floods should be less severe compared to the Great Flood in 2011, which inundated 90 billion square kilometers of land.
