Thunderstorms 70% in Bangkok; Small Boats Advised to Stay Ashore as Heavy Rain Hits 10 Provinces

The Meteorological Department has warned that Bangkok has a 70% chance of thunderstorms and advised small boats to remain ashore. Meanwhile, heavy to very heavy rain warnings have been issued for the central region and 10 other provinces, which could affect travel and riverside communities on August 7–8. Local authorities are monitoring water levels and preparing emergency response measures.

Reports say a weather system moving through the area is producing extensive cloud cover and widespread rainfall. The department urged the public to follow weather updates closely, especially residents near canals and low-lying areas at risk of flash floods. Bangkok’s Drainage Department has opened an operations center to monitor water levels and has readied pumps to speed drainage in likely accumulation points.

For road users, the Bangkok Traffic and Transport Department recommended allowing extra travel time during heavy rain because traffic will be congested and main roads may have many flooded spots. Public transport could be delayed and some routes may be temporarily diverted. The department also asked people to avoid driving in deep floodwater and to obey traffic officers’ instructions.

Operators of passenger and small cargo vessels have been warned by port authorities and related agencies to suspend sailing temporarily in risky areas, as strong winds and reduced visibility could increase the risk of water accidents. They were also advised to check safety equipment such as life jackets and to prepare emergency plans in case weather conditions change rapidly.

The impact on local communities is clear, especially wet markets, roadside eateries and street vendors whose incomes may fall during heavy rain. Some schools are considering ending classes early or delaying start times for student safety. Construction work and outdoor projects have been paused to avoid risks to workers and damage to materials. Temporary shelters are being prepared for residents in at-risk areas should flash flooding occur.

Authorities asked residents to take basic preparedness steps, including stocking food and drinking water, inspecting homes, and storing valuables in high places. They also urged people to follow guidance from official agencies and trusted news sources, and to avoid sharing unverified rumors or images that could cause unnecessary alarm.

In such volatile weather, cooperation among government agencies, the private sector and local communities is crucial to mitigate impacts and protect the public—particularly in large cities like Bangkok that are already vulnerable to flooding. Preparedness and effective communication will help reduce damage and safeguard people’s lives and livelihoods in a timely manner.
