URGENT - WINTER WEATHER MESSAGE
National Weather Service Des Moines IA
1151 AM CST Tue Mar 4 2025

...BLIZZARD CONDITIONS TONIGHT THROUGH WEDNESDAY WITH INTENSE WINDS 
AND SNOW...

.A strong early spring system is set to affect Iowa later today 
through tonight into Wednesday. Rain will quickly change to snow 
from northwest Iowa to southeast Iowa overnight as winds intensify 
from the northwest and become strong with gusts near or above 60 
mph. The combination of these winds with falling snow will cause 
significant visibility reductions with a period of blizzard 
conditions expected. Blowing and drifting snow with whiteout 
conditions, particularly in open, rural areas, will make travel 
dangerous at times tonight into at least a part of Wednesday 
morning. Even as the falling snow ends, blowing snow and visibility 
restrictions may persist. Conditions are expected to gradually 
improve later Wednesday as the winds slowly decrease.
