Hydrologic Outlook
National Weather Service Denver/Boulder CO
205 PM MDT Wed May 17 2017

...Moderate to heavy rain tonight through Thursday evening will
cause significant rises on area streams. Runoff will then take
several days to make its way down the South Platte River in
northeast Colorado...
...Excessive runoff may also cause localized flooding of low lying
areas...

A strong spring storm will bring abundant moisture to north central
and northeast Colorado through Friday with significant snow in the
mountains and widespread rain at lower elevations east of the
divide. However...the cooler weather should slow mountain snowmelt.
The snow level will start around 7000 feet and then lower with snow
possible along the Front Range Urban Corridor Thursday night.

Upslope flow will likely focus the heaviest rain along the Front
Range Foothills. General rainfall totals of 1 to 3 inches are
possible...with locally higher amounts in and near the foothills.

At this time it looks like smaller creeks and streams in and near
the foothills will run high but generally remain below bankfull.
Minor flooding could be an issue along the South Platte River on the
northeast plains late this week and the lower Cache la Poudre River
in Weld County could possibly rise above bankfull.

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