The Thai Meteorological Department warned today (Wednesday) that most parts of Thailand, which have been hit by heavy rain over the past few days, are expected to face more rain later this week, due to the influence of tropical storm “Conson”.

Also known as “Jolina” in the Philippines, “Conson” will head west over the South China Sea, possibly reaching Hainan Island, China or northern Vietnam. This may cause heavy rainfall in north eastern Thailand, said the Met Dept.

Heavy rains, which have been lashing the northern, north eastern and central regions, including Bangkok, over the past few days, bringing heavy flooding to Pattaya and Prachin Buri, are the result of a monsoon trough compounded by a cyclonic weather system looming over the central plains.

This weather pattern will prevail for two more days, after which it will move into the Andaman Sea and this will cause heavy rain covering over 80% of Thailand.

The provinces struck by heavy rain yesterday were:

• Chon Buri, 194.2mm
• Nakhon Ratchasima, 113.5mm
• Rayong, 91.3mm
• Samut Prakan, 87.6mm
• Prachuap Khiri Khan, 80mm
• Lamphun, 70.5mm
• Buriพam, 68mm
• Suphan Buri, 64.1mm
• Prachin Buri, 61.9mm
• Krabi, 61.2mm

In the eastern province of Sa Kaeo, the chief of the Pang Sida National Park, ordered the closure of the Pang Sida waterfall today after it was hit by a flash flood.

The National Water Resources Office is warning of possible flash flooding and mud slides in 30 provinces in the northern, north eastern and eastern regions from today until the weekend.
