Heavy rains fuelled by two storm systems, one of them remnants of hurricane Patricia, have pounded south-eastern Texas, triggering flash floods in Houston and derailing a freight train.
Forecasters predicted 15-30cm (6-12in) of rain for coastal areas of the US, including south-west Louisiana, by Monday morning, exacerbated by tides up to 1.5 metres (5ft) high and wind gusts of up to 35mph.
The rain systems were intensified by the remnants of hurricane Patricia, which was downgraded to a tropical depression after crashing into Mexico’s west coast.
