Colorado floods leave hundreds unaccounted for
Stranded residents brace for a new round of heavy rain

More than 500 stranded victims of major flooding in Colorado braced for a new round of heavy rain on Sunday that is threatening to impede rescue efforts.

New flash floods were expected to inundate the area, which thousands were forced to evacuate. A flash flood watch was in effect through the evening for the entire Denver metro area, as well as the northern Front Range Foothills and mountains.
On Saturday, large hail the size of peas or even marbles pummelled parts of the city of Aurora, according to local weather reports. A series of thunderstorms also struck the area.
Raging floodwaters in the city of Boulder, already confirmed to have killed at least four people, apparently claimed the life of a fifth on Saturday - a 60-year-old woman swept away in the torrent.
