URGENT - WINTER WEATHER MESSAGE
National Weather Service Des Moines IA
317 AM CST Sun Jan 24 2021

...Winter Storm Monday and Monday Night..

.A significant winter storm is expected to impact much of central
and southern Iowa Monday and Monday night. Snow possibly becoming
a wintry mix at times, will begin across far southern Iowa late
tonight then will expand north into central Iowa during the day
Monday. Heavy snowfall rates are likely with this storm, in
particular, during Monday afternoon and will result in widespread
moderate to heavy snow. Increasing northeast wind may gust over 30
mph at times and will cause moderate blowing and drifting. Some
uncertainty remains on the north edge of the snow band, where a
sharp gradient in snow totals is likely. The most uncertain areas
have been placed into a Winter Storm Watch.

* WHEN...Until noon CST Tuesday.

* IMPACTS...Plan on snow covered roads and low visibilities,
  especially overnight. Travel may become near impossible at 
  times. Areas of blowing snow could significantly reduce 
  visibility and cause blowing and drifting of snow. Near blizzard
  and whiteout conditions are possible with travel not 
  recommended in many locations.

* ADDITIONAL DETAILS...This may be a historic event with snow 
  amounts of this magnitude only occurring once every 15 to 20 
  years. For example, in Des Moines there have only been nine 12 
  inch daily snowfalls since 1884.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If you must travel, keep an extra flashlight, food, and water in
your vehicle in case of an emergency. The latest road conditions
for the state you are calling from can be obtained by calling
5 1 1.
