TERESOPOLIS, Brazil (AP) - A break in the rain is allowing helicopters to deliver badly needed food and water to remote areas of Brazil that have been cut off by mudslides.

Once the clouds lifted, about a dozen helicopters began flying supplies to isolated mountain communities.
      
Days of heavy rain sent tons of earth and rock crashing down steep mountainsides, burying an area of about 900 square miles. More than 600 people have died, and officials fear the death toll will rise as rescuers reach more areas.
      
A police commander says there's no longer any hope of finding people alive after four days buried under mud.
      
Survivors have complained of receiving no help. But officials say it was impossible to get helicopters in until today because of the cloud cover. The area is full of steep mountains with jagged peaks that make navigation difficult even in good weather.
