URGENT - WINTER WEATHER MESSAGE
National Weather Service Des Moines IA
827 AM CST Fri Feb 24 2017

...Blizzard Conditions Persist over Northern Iowa Today...

.The heaviest snow has ended with this system, but a prolonged
period of varied snowfall intensities will continue through this
evening. Winds will remain strong as well so the combination of
already fallen snow and any additional snow will continue to
create blizzard conditions over northern Iowa, especially in
rural, open areas. Farther south into central Iowa, a period of
drizzle, freezing drizzle and eventually light snow and blowing
will also contribute to hazardous travel conditions.

...BLIZZARD WARNING REMAINS IN EFFECT UNTIL MIDNIGHT CST
TONIGHT...

* SHORT TERM TRENDS...Snow will pick back up in intensity this
  morning as another round of snow moves across the warning area.
  Visibilities will lower as the snow increases with visibilities
  below one half mile common and reductions below one quarter from
  time to time in blizzard conditions, mainly in open,rural
  areas.

* ADDITIONAL SNOW ACCUMULATIONS...2 to 4 inches.

* WINDS/VISIBILITY...Northerly winds at 20 to 30 mph with gusts
  near 40 mph. Visibility will be reduced below one half mile for
  long periods with occasional white-out conditions, especially
  in rural areas.

* IMPACTS...Travel has become very dangerous to near impossible
  as blowing and drifting snow reduces visibility today. Many
  tow bans are in effect across northern Iowa with travel not
  advised along Interstate 35 from Story City north to the
  Minnesota border.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Blizzard Warning means severe winter weather conditions are
expected or occurring. Falling and blowing snow with strong winds
and poor visibilities are likely. This will lead to whiteout
conditions, making travel extremely dangerous. Do not travel. If
you must travel, have a winter survival kit with you. If you get
stranded, stay with your vehicle.
