They may be in advisory if they think ORH is just a lolli and everyone else will get less. I think they need at least half the zone (county) to be at or above the minimum criteria in order to issue the warning, so if the northern part of the county or highest elevations are getting a foot, and everyone else is getting 6-8 then it's just an advisory. Also, the minimum thresholds are 7 inches in 12 hours or 9 inches in 24 hours, so the long duration would mean it's just an advisory level storm.
