BANGKOK, THAILAND – The Thai Meteorological Department issued an urgent warning for a three-day period of extreme weather expected to sweep across the country from 31 October to 2 November 2025.
Forecasters predicted intense thunderstorms, torrential rain and abrupt temperature drops, urging residents to prepare for potentially hazardous conditions.
Low-pressure system drives widespread instability
A low-pressure system from Cambodia was identified as the driver behind the sudden weather shift. Moving along a monsoon trough, it was expected to spread across Thailand’s eastern, central and southern provinces, colliding with moist easterly winds and releasing high levels of energy into the atmosphere.
According to official notice No. 314/2025, the agency described the event as the seventh such national warning this year. Provinces including Chaiyaphum, Nakhon Ratchasima, Kanchanaburi and the coastal destination Prachuap Khiri Khan were among the regions most likely to face severe storms.
Cold air chills the northern highlands
While floods and lightning threatened southern and central areas, the northern provinces were forecast to experience an unseasonable cold snap. Daytime temperatures were expected to fall to 20–25°C, and on mountain peaks, residents could wake to frigid conditions as low as 8°C.
In some upland districts of Tak, Kamphaeng Phet and Phetchabun, the mercury might drop close to freezing. A steady northeasterly wind of 10–15 km/h was expected to push cool air further south, intensifying the chill through valleys and highlands.
Central Thailand and Bangkok prepare for urban flooding
The central region — including Nakhon Sawan, Lopburi, Kanchanaburi and Bangkok — faced a 70% chance of heavy thunderstorms that could overwhelm drainage and trigger flash floods. Temperatures in the capital were forecast at 30–33°C by day and a noticeably cooler 22–25°C at night, with gusting northeasterly winds between 10–20 km/h.
Authorities warned drivers to take extreme care due to slippery roads and potential waterlogging.
“DRIVERS ARE URGED TO EXERCISE MAXIMUM CAUTION AS VISIBILITY AND TRACTION WILL BE SIGNIFICANTLY REDUCED,”
the department stated.
South sees dangerous seas and travel risks
Further south, the situation looked equally severe. Along the Andaman coast, including Phuket, Krabi and Phang Nga, about 70% of the area was forecast to face violent storms. Winds shifting to the west at 15–35 km/h were expected to generate waves up to two metres high, posing a clear threat to small vessels and swimmers.
• Boating and water sports were declared highly dangerous
• Tour operators were advised to delay sea excursions
• Holidaymakers were told to avoid beaches during storm hours
On the Gulf of Thailand’s eastern coast, including Prachuap Khiri Khan, Chumphon and Surat Thani, heavy rainfall was also anticipated, with risks of coastal flooding in low-lying zones.
Damage concerns in the farming sector
The weather bureau issued an additional warning to farmers, cautioning that persistent downpours could threaten rice fields and fruit plantations.
“STRONG WINDS AND TORRENTIAL RAIN COULD CAUSE SERIOUS DAMAGE TO CROPS, PARTICULARLY IN FLOODED REGIONS,”
specialists noted.
Residents were told to stay alert and monitor official channels closely. Flood-prone communities, particularly those near rivers and lowlands, were strongly advised to relocate animals, secure equipment, and avoid traveling through inundated areas.
Public information and emergency contact
The Meteorological Department opened 24-hour hotlines (0-2399-4012-13 or 1182) for weather inquiries and posted real-time alerts on its official website. Officials stressed that updates would be released as the system developed.
“PLEASE FOLLOW THE WEATHER ADVISORIES CLOSELY — THESE CONDITIONS CAN CHANGE RAPIDLY,”
the department warned.
As Thailand entered this turbulent three-day period, meteorologists emphasized cautious optimism: while such events were not unprecedented during the late monsoon season, the combination of cold air, heavy rain and coastal winds could still disrupt travel, agriculture and daily life nationwide.
