                  WHAT DOES THAT WARNING MEAN?

When a warning is issued during the winter season, will you know
what it means, and will you know how to respond. During this
Colorado Winter Weather Preparedness Week, please become familiar
with our list of potentially life-saving winter weather products.


A Hazardous Weather Outlook is issued daily by each National Weather
Service office serving Colorado, providing information on potentially
hazardous weather out to 7 days into the future.

                      WATCHES AND WARNINGS

A Winter Storm Watch is issued when hazardous winter storm conditions
are possible within the next 3 to 4 days, but the timing, intensity,
or occurrence may still be uncertain.

In contrast, a Winter Storm Warning is issued for potentially
life-threatening winter storm conditions, such as heavy snowfall or
a combination of snowfall and blowing snow, which are likely to
occur within the next 1 to 2 days.


Advisories for winter weather are issued for potentially hazardous
conditions which are considered more of a nuisance than a
life-threatening situation. However, if caution is not taken the
advisory events could become life-threatening.

A list of winter weather warning and advisory products, as well as
the criteria for each type of warning and advisory, can be found at by clicking on the Preparedness link under the
WEATHER SAFETY menu area near the bottom of the page.

Winter Weather Preparedness Week in Colorado will continue through
