Heavy Rainfall Causes Flooding and Traffic Delays in Bangkok
Severe rain on September 25, 2026, caused the Saen Saep Canal to overflow, leading to significant flooding and traffic congestion on Lat Phrao Road.
On the morning of September 25, 2026, heavy and continuous rainfall across Bangkok and its surrounding areas resulted in significant flooding on several major roads. According to reports from JS100 Radio (FM 91), the weather conditions have severely impacted traffic flow, particularly in the Bang Kapi district.
By 08:48, traffic on Lat Phrao Road, moving from Bang Kapi Intersection toward Lam Sali Intersection and Srinakarin Road, was reported to be moving very slowly due to water accumulation. By 09:15, the situation worsened as water from the Saen Saep Canal overflowed onto the left lane of Lat Phrao Road near the Bang Kapi Market. Similar flooding was observed on the inbound side of Lat Phrao Road near Soi 144.
For residents and travelers, these conditions mean significant delays for those commuting through the Bang Kapi area. Motorists are advised to expect slow-moving traffic and potential hazards due to standing water. As of the latest reports, rain continues to fall in the affected areas, and the full extent of the impact on secondary roads remains to be confirmed. Authorities have not yet provided a timeline for when the water levels will recede or when traffic flow will return to normal.
