Very warm air flowing over the colder waters of the Mississippi
River and Lake Pontchartrain, Lake Maurepas and Lake Borgne has
allowed patchy dense fog to develop, especially on the Mississippi
River, and anywhere roadways are crossing these bodies of water.
Traffic and web cameras indicate very low visibilities in these
areas, as low as one quarter to one half mile in some locations.
Mariners on the Mississippi River and travelers crossing water
should be prepared for rapid changes in visibilities this morning
and exercise caution until conditions improve.
