The reason this one is so bad is that the entire Mississippi river, all the way back to its sources is at or past flood stage.

The result is that the drain to the gulf is full and already past capacity. The rain will obviously have to make new drains through the cities of the lower gulf.

'CANNOT PUMP OUR WAY OUT'

New Orleans Mayor LaToya Cantrell warned that 48 hours of heavy rainfall could overwhelm the pumps the city uses to fight floodwater, leading to flooding as early as Friday morning.

"We cannot pump our way out of the water levels that are expected to hit the city of New Orleans," Cantrell said. "We need you to understand this."

Water pumps already were working at capacity after heavy rains, she said.
