Boomerang weather flipping parts of Colorado to unseasonably high temperatures and back to cool and wet conditions again are expected to keep the flash flood warnings coming Thursday, the National Weather Service said today.
Hot and dry weather conditions expected Thursday will increase snowmelt, followed by cool and wet conditions starting Friday through the weekend.
A flash-flood warning has been issued for west-central Las Animas County in southeastern Colorado where a slow-moving storm has dumped 2 to 3 inches of rain.
A flood warning was issued by the Weather Service for Eagle County because of fast and high flows in the Eagle River and some of its tributary streams. Also near Gypsum, the Eagle River remains high causing flooding in some nearby agricultural areas.
Increases in snowmelt caused The Pueblo Reservoir to flood causing high water levels in the Arkansas River from below the dam to Avondale.
The river is expected to fall below flood stage by Thursday, according to the Weather Service. The Arkansas River in Fremont County at Cañon City is flowing above flood stage but is expected to recede by Thursday afternoon.
An advisory was issued for the St. Vrain River and Boulder Creek in Boulder County and the Cache La Poudre River in eastern Larimer County because the water is overflowing banks in low lying areas.
In Weld County, near Greeley, both 71st and 83rd avenues between F and O streets were closed due to flooding. The area where Weld County Road 29 crosses the Cache La Poudre River is closed and parts of the the Poudre River Trail are flooded from Windsor to Greeley. The South Platte River near Kersey are expected to rise out of their banks and possibly flood nearby fields.
A small stream flood advisory was announced for east central Summit County including Silverthorne. The Blue River below Dillon crested just above the banks increasing the threat of flooding yards and walkways in the neighboring South 40 Subdivion in northern Silverthorne.
Around 5 p.m. Wednesday, water from the Fryingpan River began overflowing into a mobile home park in Basalt. The Weather Service expects more minor flooding in Basalt.
Advisories were also issued for Routt and Mesa Counties.
