Bangkok, July 3, 2025 – The Thai Meteorological Department (TMD) has issued an urgent weather warning as heavy rainfall is forecast to sweep across 49 provinces today, with nearly 70% of the affected areas expected to face intense downpours. The alert covers multiple regions, including Bangkok and its vicinity, raising concerns over potential flash floods, sudden water surges, and landslides in vulnerable zones.

Severe Weather Conditions

The TMD attributes the extreme weather to a strengthening southwest monsoon over the Andaman Sea, Thailand, and the Gulf of Thailand, coupled with a low-pressure system near northern Vietnam. These conditions are expected to trigger heavy to very heavy rainfall in several areas, particularly in the northern, northeastern, central, and eastern regions. Coastal provinces along the Andaman Sea have been cautioned about rough seas, with waves reaching 1-2 meters and even higher during storms.

High-Risk Areas

The warning spans key provinces, including:

• Northern Thailand: Chiang Mai, Chiang Rai, Phitsanulok, and Tak

• Northeastern Region: Nakhon Ratchasima, Ubon Ratchathani, and Khon Kaen

• Central & Eastern Zones: Ayutthaya, Kanchanaburi, Chonburi, and Rayong

• Bangkok & Surroundings: The capital faces a 70% chance of heavy rain, with flood-prone districts under close watch.

Authorities have urged residents in low-lying areas, near hillsides, and along waterways to remain vigilant. The Bangkok Metropolitan Administration (BMA) has mobilized its Drainage and Sewerage Department to clear clogged waterways and monitor eight high-risk flood zones. Emergency response teams in other provinces are also preparing for possible evacuations.

Public Advisory

The TMD advises the public to stay updated on weather forecasts, avoid travel through flooded roads, and prepare emergency supplies. Fishermen have been warned against venturing into turbulent seas.
