Areas of fog and low clouds are noted in satellite imagery, surface observations, and local traffic cameras over north central Florida over parts of Marion county and Putnam county. The fog will linger through 830 AM and may drift a bit further north and east toward Clay or Alachua counties. The fog may be locally dense to a quarter of a mile at times. The nature of the fog is such that visibilities will vary greatly over short distances. Motorists should be alert for rapidly changing conditions through sunrise.
