A Winter Weather Advisory is issued when there could be slick spots caused by a couple of inches of snow or light amounts of sleet, but the accumulation is expected to stay below warning criteria. One step up would be a Winter Storm Warning.
This is issued when more hazardous conditions are expected, such as 5 inches or more of snow, and sometimes sleet, is forecasted within 12 hours, and also when strong winds are expected to blow the snow and cause drifts.
It is always important to pay attention when these advisories and warnings are issued for your area. As always, you can download our Storm Shield Weather app to get winter weather alerts right to your phone to keep you ahead of the changing weather.
