Flooding caused by heavy rain in the wake of Typhoon Xangsane has killed 47 people since late August and affected up to 2.5 million people in 46 provinces, mostly in central and northern Thailand.

Water levels were falling in 28 provinces, but 18 others -- including Bangkok -- were still affected, according to the interior ministry's disaster prevention department.

Damage from the flood was estimated at 305.3 million baht (8.1 million dollars), with more than 8,000 homes damaged, the department said in a statement.
