This Hazardous Weather Outlook is for northwest Colorado, southwest
Colorado, west central Colorado, east central Utah, northeast Utah
and southeast Utah.
.DAY ONE...Today and tonight.
Snow tapers off in most areas today before the next round arrives to
the northern Colorado mountains late this evening. Significant
amounts are mainly expected across the Park and Gore Ranges with
travel impacts along Highway 40 from Milner to Rabbit Ears Pass.
Light snow over Vail Pass could also lead to minor travel impacts at
times.
.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
The first round of snow will continue to impact the northern Colorado
mountains through Friday afternoon. A more robust round of snow and
wind will then impact the northern and more of the central mountains
of Colorado and adjacent valleys Friday night through early Sunday.
Significant accumulations are possible and travel impacts including
road closures should be planned for with this second storm. The
northern Colorado mountains are likely to see additional snow events
through much of the upcoming week as well.
.SPOTTER INFORMATION STATEMENT...
Spotter activation is not expected today or tonight, however
spotters are encouraged to report snowfall amounts to the
