WARNING: Bangkok has been hit by severe floods. All districts have been placed on high alert, however, the worst-hit areas are the northern and eastern districts, most notably Sai Mai, Khlong Sam Wa, Bang Khen, Nong Chok, Min Buri, Lat Krabang and Khan Na Yao. Travelling to those districts is highly discouraged. The authorities have advised the locals there to move their valuables to higher grounds and be ready for a swift evacuation.
In other districts, including Central Bangkok, the water has risen to ankle or knee-level. While life continues relatively as normal, the situation is in a state of flux and could change overnight. Basic supplies like drinking water, tooth paste, toilet paper, batteries and candles are scarce or unavailable as many convenience stores and supermarkets have closed.
Rail travel is severely strained — the Northern Line to Chiang Mai is completely out of order, while the Northeastern Line is rerouted via Chachoengsao (expect significant delays). Bus travel is still possible, but many lines are rerouted causing heavy delays. Plan your trip carefully and follow the news for ongoing developments.
