Monsoon in Thailand intensifies, causing predictions of heavy rainfall and potential flooding
Thailand Braces for Heavy Rainfall and Potential Flooding from May 25-27
The Meteorological Department has issued a weather warning for the coming days, urging all citizens to prepare for torrential rain, flash floods, and runoff, particularly in low-lying areas and close to waterways.
This warning was issued Sunday in response to a strengthened southwest monsoon sweeping throughout the Andaman Sea and the Gulf of Thailand, combined with a powerful monsoon trough expected to cross upper Thailand and the northern region during this period.
Authorities urge residents to postpone travel in areas experiencing thunderstorms or flooded zones, exercise extreme caution while driving, and avoid landslide-prone areas, especially near slopes and riverbanks.
Sea conditions are predicted to be rough in both the Andaman Sea and the Gulf of Thailand:
- In the upper Andaman Sea, waves reaching up to 2 meters are expected, with heights peaking in stormy areas.
- The lower Andaman Sea will see waves roughly between 1-2 meters.
- The Gulf of Thailand will have waves approximating 1 meter, with higher levels in areas affected by thunderstorms.
Small boats in the upper Andaman Sea are advised to stay ashore through May 27. Although weather conditions are anticipated to improve from May 28 to 31, flood risks remain high in regions still receiving significant rainfall, such as the north and northeast.
Here's a regional breakdown of predicted rainfall and flood risks:
- The North, Northeast, Central, and Eastern regions, including Bangkok, can expect rain at times, mixed with heavy to very heavy downpours in isolated areas. Flash flooding is a high concern, especially around waterways, foothills, and lowlands.
- Western Thailand and the Andaman Sea will have occasional heavy rain showers, while coastal areas may experience waves approximately 1 meter high, with heights exceeding 2 meters during thunderstorms.
- Southern Thailand (both Gulf and Andaman sides) faces the likelihood of heavy to very heavy rain, and like other regions, flash flooding poses a threat, particularly in areas along waterways and lowlands.
With the increased rainfall and flood risks, the public is urged to stay informed, plan for potential disruptions to transportation and utilities, and practice health precautions due to the higher likelihood of waterborne diseases. Farmers should take measures to safeguard their crops, while mariners need to exercise caution at sea, staying up-to-date with maritime weather warnings and avoid sailing in thundershowers.
In summary:- Expect widespread rainfall, occasional heavy to very heavy showers, and a heightened risk of flash flooding from May 25-27.- Coastal areas should prepare for rough seas, particularly along the Andaman coast, with all ships encouraged to practice caution and avoid thundershowers.
- Given the weather warning and the heavy rainfall anticipated in low-lying areas and near waterways, it is advisable for citizens to be cautious, as environmental-science research reveals that such conditions can lead to flash floods and runoff.
- As the Meteorological Department forecasts rough sea conditions in both the Andaman Sea and the Gulf of Thailand, specifically with waves exceeding 1 meter, it is crucial for science, particularly marine science, to guide seafarers and mariners regarding the potential risks and necessary precautions.
