...Dense Sea Fog Expected into Monday Morning...

.A southerly flow will continue to push warm and moist air over
relatively cooler Gulf shelf waters. This will help produce sea
fog over the near shore waters through Monday morning. This sea
fog will also move into the coastal lakes and bays. The sea fog
is expected to be dense with widespread visibilities below 1 nm
and near zero at times. Conditions are expected to slowly improve
by mid morning Monday, as winds increase and daytime heating
starts.
