‘drove Mississippi River backwards’
The storm surge ahead of
Hurricane Isaac made the Mississippi River run backwards for 24 hours. US
Geological Survey (USGS) instruments at Belle Chasse in Louisiana recorded the
flow of the river, finding it running in reverse on Tuesday. The flow reached
nearly 5,200 cubic metres per second (182,000 cubic feet per second) upriver,
with a height of nearly 3m (10ft) above average.
