Severe monsoon warning issued for Thailand with heavy rainfall

[webfact]

The Thai Meteorological Department (TMD) has issued a warning for severe monsoon conditions across Thailand, particularly in the northeast and eastern regions, with heavy to very heavy rainfall expected.

 

Residents are advised to be cautious of sudden flooding and flash floods, while the sea will experience waves up to 2 metres high, prompting advisories for sailors to avoid navigating the Gulf of Thailand and the Andaman Sea.

 

The Thai Meteorological Department forecasts weather conditions for the next 24 hours, indicating a continuing influence of the southwesterly monsoon covering the Andaman Sea, Thailand, and the Gulf of Thailand. Additionally, a low-pressure area over northern Vietnam contributes to persistent thunderstorms and heavy rainfall in several parts of northern, eastern, and southern Thailand.

 

The public is urged to be vigilant for potential flash floods and rapid water flow, particularly in areas near slopes, watercourses, and low-lying regions.

 

The upper Andaman Sea, stretching from Ranong province upwards, is expected to have sea waves ranging from 1 to 2 metres. In regions experiencing thunderstorms, waves may exceed 2 metres. Mariners are advised to exercise caution and avoid sailing in areas with thunderstorms during this period.

 

Issued on August 8, the weather forecast for Thailand from 6am today to 6am tomorrow is as follows:

In the north, there will be thunderstorms affecting 60% of the area, with heavy rainfall in Tak, Kamphaeng Phet, Phichit, Phitsanulok, and Phetchabun provinces. Temperatures will range from 23 to 25 degrees Celsius at the lowest and 32 to 35 degrees Celsius at the highest. The southwesterly winds will blow at a speed of 5 to 15 kilometres per hour.

 

The northeast will experience thunderstorms in 40% of the region, mainly affecting Nong Khai, Bueng Kan, Sakon Nakhon, Nakhon Phanom, Chaiyaphum, Khon Kaen, and Nakhon Ratchasima provinces.

 

Temperatures will range from 24 to 26 degrees Celsius at the lowest and 34 to 35 degrees Celsius at the highest. The southwesterly winds will blow at a speed of 10 to 20 kilometres per hour.

Yes, always makes me laugh when I see these wind speeds as something bad during a storm.  Imagine a hurricane like we get in the UK hitting Thailand.

Looked up Phetchabun on international weather centers and they forecast some sprinkle (2 to 6 mm).
