Special Weather Statement issued March 9 at 4:03AM EDT by NWS Miami FL

Areas of fog…some locally dense…are developing across portions
of the area. Visibilities have dropped below 1 mile in some
locations, and are likely continue decreasing, with localized areas
experiencing reduced visibilities to one-half of a mile at times.
Fog will likely persist through the early morning hours after
sunrise. If lower visibilities materialize, a dense fog advisory
will be needed.

Motorists are advised to drive with caution this morning as
visibilities may widely vary over short distances. Use low beam
headlights and leave extra distance between your vehicle and others
on the road when encountering significant reductions in visibility.
Allow extra time to travel to destinations.
