...DENSE FOG ADVISORY IS CANCELLED...

Visibilities have generally improved across the Valley this morning,
and as such the Dense Fog Advisory has been cancelled. Lingering
patches of dense fog will continue through the early afternoon,
especially in the northern San Joaquin Valley. The potential for
widespread dense fog returns tonight into tomorrow morning. Remember
to slow down and use low-beam headlights when driving in fog.
