Hydrologic Outlook
National Weather Service Denver/Boulder CO
1050 AM MDT Thu May 18 2017

...Light to moderate rain will continue today east of Interstate 25.
Excessive runoff could cause standing water in low lying areas and
eventually minor flooding along the South Platte River on the
northeast plains...

A potent spring storm will continue to bring colder temperatures and
widespread precipitation to north central and northeast Colorado
through Friday afternoon before tapering off. Light to moderate rain
will continue east of Interstate 25 with the best forcing today...
tapering off and transitioning to snow or a mix of rain and snow
tonight. The precipitation will generally fall as snow or a rain and
snow mix west of Interstate 25 which will slow some of the runoff.

Upslope flow has brought 0.5 to 2 inches of precipitation to many
locations in the Urban Corridor. The heaviest rain since Wednesday
evening has been in the Greeley to Windsor to Eaton area in Weld
County where 1.4 to 3.25 inches has fallen. NWS Spotters reported
6.5 to 18 inches of snow in the Front Range Foothills.

There have been significant rises on rivers and creeks from Denver
northward. Smaller creeks and streams in and near the foothills are
forecast to run high but are forecast to remain below bankfull. The
South Platte River near Kersey in Weld County could rise near flood
stage Friday and farther east on the plains there could be low lying
areas along the river flooded this weekend. However...it is
dependent upon how much of the precipitation in the South Platte
Basin falls as frozen versus liquid precipitation.

Pay attention to the weather...creek and river levels. Do not get
close to flooded streams.
