  • Heavy rain, strong winds, and thunder hit Bangkok after midday, causing flooding on several roads.
  • The Bang Khen Roundabout and Ram Intra Road were significantly impacted, with floodwaters reaching up to 20 centimeters.

Bangkok residents should check their routes after heavy rain, thunder and strong winds hit the capital from noon, flooding parts of Bang Khen.

The situation was particularly critical around Bang Khen Roundabout and Ram Intra Road, where floodwater reached 20 centimetres, causing traffic congestion and slowing vehicles as officials rushed to drain the water.

The Thai Meteorological Department (TMD)reported today’s weather conditions and warned people not to drop their guard as large rain clusters were moving in and overlapping.

Rain was expected to last for more than an hour, and people were advised to check alternative routes before leaving home.

The key location of Bang Khen Roundabout had floodwater waiting to drain at a depth of 15-20 centimetres, causing traffic congestion to build up around the area.

Small vehicles should exercise extreme caution.

Officials from the Bang Khen District Office have gone into the area and taken up positions to speed up urgent drainage.

They were also helping to remove rubbish to clear waterways and prevent drainage pipes from becoming blocked.

Later, at 1.30pm, the situation remained worrying.

Flooding was found at the mouth of Ram Intra Soi 5 and on Ram Intra Road from the area in front of the Ramintra Post Office branch, with about 15 centimetres of water on the road surface waiting to drain.

Cars were moving slowly and stopping intermittently.

People using the route were asked to avoid it unless necessary.
