  Day 7 - Understanding Winter Weather Terms

 

Today marks the conclusion of Winter Hazards Awareness Week in Michigan. The Michigan Committee for Severe Weather Awareness reminds all Michigan residents to pay heed to weather forecasts, advisories, watches, and warnings as they enter another winter season. There are a few winter weather terms described here to help in understanding those forecasts.

  • Winter Storm Watch: Severe winter conditions such as heavy snow and/or ice are possible within 12 to 48 hours. Prepare and make plans now.
  • Winter Storm Warning: Severe winter conditions have begun or are about to begin. Stay indoors.
  • Blizzard Warning: Snow and strong winds will combine to produce a blinding snow (near zero visibility), deep drifts, and life threatening wind chill. Seek refuge immediately.
  • Winter Weather Advisories: Winter weather conditions are expected to cause significant inconveniences and may be hazardous. Exercise caution, especially while driving. Winter Weather Advisories can be issued for a number of winter weather elements including snow, freezing rain, and lake effect snow.
  • Wind Chill Advisory: Wind chill temperatures of -15ºF to -24ºF for Southern Lower Michigan, -20ºF to -29ºF for Northern Lower Michigan, and -25ºF to -34ºF for the Upper Peninsula of Michigan.
  • Wind Chill Warning: Wind chill temperatures of -25ºF or colder for Southern Lower Michigan, -30ºF or colder for Northern Lower Michigan, and -35ºF or colder for the Upper Peninsula of Michigan.
  • Snow Squall Warning: An intense short duration burst of snow with gusty winds that reduces visibility to near zero along with sub-freezing ambient road temperatures or plunging temperatures sufficient to produce flash freezes on roads, especially on limited access highways.
