Patchy dense fog persists across some locations in the Upper
French Broad River Valley from around Rosman to Brevard and Pisgah
Forest. Visibility will be sharply reduced, in some cases to one-
half mile or less. Temperatures were close to freezing in most of
Transylvania, so freezing fog could result in some slippery spots
on bridges and overpasses if the road has not been treated. The
fog should dissipate around daybreak.
