Authorities expect 50-70mm of rain over 24 hours on Sunday in Pua, Song Khwae, Chiang Klang and Thung Chang, where soil is already saturated, so runoff will be faster. Muang Nan's commercial centre has receded to near-normal, and recovery work on homes, shops and roads is under way. If you run a business in Nan or ship goods through it, check on stock stored at low levels, plan for road cut-offs (the Fai Chao bridge in Pua was washed away, leaving 14 villages isolated), and follow official warnings from agencies. Officials say daily activity can continue as normal.
