What a winter weather advisory means
A winter weather advisory is issued for winter precipitation that is expected to cause significant inconvenience: slick roads, slower commutes and possible school delays. Totals stay below the local winter storm warning criteria, but even light freezing rain or a thin coat of snow can cause many crashes.
