Guatemalan officials say there is little hope more survivors will be found in two villages buried by mudslides caused by Hurricane Stan.

The official death toll from the mudslides stood at 508 as of Saturday but officials say at least 1,400 other people are missing and presumed dead in the towns of Panabaj and Tzanchaj.

Huge slides of mud and rock came crashing down on the towns from the San Lucas volcano Wednesday. Rescue workers continue searching for victims but have been hampered by driving rain that has washed out many bridges and roads.

Floods and landslides triggered by Stan have killed more than 600 people overall, including 67 in El Salvador, at least 20 in Mexico, 10 in Nicaragua, and four in Honduras.
