Fast moving storms that bring with them heavy rains are causing flooding in several places in the Colorado Foothills.

In Boulder, some streets were flooded and businesses such as the library and Municipal Building were evacuated.

Near Greeley, the Poudre River and other bodies of water are already full due to melting snow. Any more water will likely cause them to flood quickly. The Poudre River is already past flood stage and a flood warning is in effect until it falls below flood stage.

Bridges and roads near the Poudre have been closed as water overflows onto them.

More isolated storms are expected Saturday afternoon and severe weather along the Front Range and eastern plains is possible. The concerns during these storms is the damaging winds and large hail. The storms should move out by the evening.

Some storms could drop heavy rains quickly, at a rate of 1 to 2 inches per hour.

Water activities like tubing and rafting are being restricted due to the high levels. Last week a 14-year-old boy and his dad were swept away in the Poudre River. A rafter also disappeared in the Colorado River.

Friday, officials in Boulder County were concerned of the possibility of rock slides.

Elsewhere in Colorado, police are warning parents to keep their children away from the banks of Clear Creek near Wheat Ridge.

"Residents and park visitors should be on the lookout for rising waters and should never attempt to cross flooded paths or bridges," according to a news release.

North central and northeastern Colorado are still areas of concern Saturday. The grounds are saturated and rain has nowhere to go.

Sunday, the weather appears to be dry in most of Colorado. Only a 10 percent chance of rain is forecasted.

Colorado last experienced heavy flooding September 2013.
