Brazilians struggle to keep their heads above water as near-record flooding sweeps through the Amazon.

Thousands in districts along the Rio Negro River have been forced to leave their homes, while officials declared a state of emergency in the affected area.

And it could get worse before it gets better.

Weather forecasts predict that water levels will likely rise beyond the record set in 2009 within the month.

(SOUNDBITE) (Portuguese) RESEARCHER OF THE NATIONAL INSTITUTE OF AMAZONAS' RESEARCH, JOCHEN SHONGART, SAYING:

"This year's flood will surpass the volume of the 2009 flood. It will be the largest flood ever registered. At least that is what we can conclude from our database."

The news is unwelcome to residents doing their best to ward off water and pests.

This woman says she's seen homes completely flooded and full of snakes and rats.

Climate analysts blame the record floods on the La Nina weather effect and warming temperatures across the globe.
