Heavy afternoon rain flooded roads in western Bangkok on October 17, 2026, as a gauge in Nong Khaem recorded 102.5mm over three hours and motorists were warned away from a waterlogged junction in Bang Bon.
Bangkok’s flood prevention centre reported the Nong Khaem reading, the highest in its update, at 2.30pm. The centre said light to moderate rain remained across the Thonburi side and riverside areas, moving westwards.
Rainfall ranged from moderate to very heavy, with western Bangkok bearing the brunt of the downpours.
Bang Bon junction flooded as storms disrupt roads
Bang Bon district office warned at 1.20pm that deep standing water at the Bang Bon three-way junction posed a risk to small cars and motorcycles.
The office urged those road users to avoid the junction to prevent their engines stalling.

TMD’s 2pm forecast tracked rain moving west

Lighter rain in Nonthaburi and Pathum Thani were also reported.
Floodwater, gusts and poor visibility pose travel risks
Three main hazards for residents and travellers:
- Roadside flooding and waterlogged low-lying lanes: Accumulated rainwater could exceed drainage capacity.
- Gusty winds: Branches could break and unstable structures could be damaged. Particular caution was urged near tall structures, billboards and weakened trees.
- Slippery roads and reduced visibility: Wet conditions increased the risk of traffic accidents.
