Six hours of steady, often torrential, rain produced yet another miserable commute for Bangkokians weary of rainy-season floods that never end.

Thunderclaps and lightning exploded across the capital around 2:30 a.m. Tuesday as the active monsoon trough laid out across the lower North, upper Central and lower Northeast regions, bringing heavy downpours.

Pre-dawn photos and videos foreshadowed the rush-hour chaos, with water already topping wheel wells of minivans and taxis as late-night party people tried to boat home.

By sun-up flood levels in many parts of the region already was knee-deep, with people needing to trade in their Wellies for hip-waders.

Car and truck traffic moved at a crawl throughout Bangkok, but motorbikes often ended up too deep to motor through.

The Thai Meteorological Department said Bangkok today would remain cloudy with widespread thundershowers and isolated heavy rains. Minimum temperatures are expected to range from 25-27 °C and maximum temperatures from 32-37 °C. Southwesterly winds  will blow at 10-25 kilometers an hour.
