VFR not recommended

VFR (visual flight rules) not recommended

An advisory provided by an FSS (flight service station) to a pilot during a preflight or an in-flight weather briefing that flight under visual flight rules is not recommended. This clearance is given when the current and/or forecast weather conditions are at or below VFR minimums. It does not abrogate the pilot's authority to make his or her own decision.
