... Areas of dense valley fog expected overnight...
Recent rainfall combined with clear skies and light winds will
allow for areas of dense valley fog to form overnight.
Visibilities of a quarter of a mile or less at times are expected.
Exercise caution near intersections where visibilities are reduced
and allow extra time to reach your destination.
