County officials are telling people to avoid floodwaters, which may be contaminated with sewage and contain unseen hazards such as nails. Some communities in Boulder and Weld counties, including Lyons, Firestone and Frederick, are under boil water advisories.
The floods that have repeatedly inundated large parts of central and northeastern Colorado since Wednesday likely killed more than the four people who have been confirmed dead, officials say. The search for victims has taken second priority to rescue and relief operations, as agencies rush to help people who remain at risk. President Obama has declared a major disaster in the area.
For a second day flood waters, goaded by heavy rains, impacted large swaths of the Front Range. When skies finally broke, many were stranded, hundreds were in need of rescue and four lives were lost statewide.
